Face-to-face interactions stimulate your newborn’s brain in ways that pave the way for language learning. This according to fascinating new research from Dr. Patricia Kuhl and colleagues at the I-LABS. We’ve long known that serve and return stimulates the infant brain and supports parent/child bonding. But now, through use...

@UW_ILABS Those first 1001 days from conception are so important and especially those face 2 face interactions with serve & return are vital. Has anyone been able to look at adults with poor serve & return communication skills and mapped back to their very early days interactions?

@UW_ILABS It's nice to know, after all these years, that I did something right. My grown children are all quite verbal and all are good writers. Two of them enjoy writing books. I loved the face-to-face interaction!❤️

@UW_ILABS My mother called it “cooing.” It’s so easy to follow baby’s lead with tone and volume for the perfect “conversation.”

Want to see a baby make 60 million neural connections? 🧠 Look no further than this fantastic video. As they bide a little time in the car, our hero and his dad engage in this lovely “serve and return” interaction. And it’s hard to tell which of them is loving it more. If you’re a new parent or grandparent, know that these face-to-face, back-and-forth interactions are one of the very best ways to light up your baby’s developing brain. At birth your baby’s brain is home to up to 100 billion neural (nerve) cells - but depends heavily on early experiences and interactions to help create the connections between them that will go on to undergird language and more sophisticated forms of cognition. During the earliest months of life researchers estimate that these neural connections occur at a rate of one million per second - meaning that 60 million or more occur over the course of this beautiful one minute conversation. Talk, talk, talk to your baby. The payoff will be huge. This loving father and son duo was shared to TT by smileybunch.

Your baby’s brain isn’t the only one that’s developing. I’ve written a good bit about the brain development of newborns and how to stimulate it. But today I want to talk about the developing brains of parents - which research suggests also change concurrent with pregnancy and childbirth. Changes in adult brains thought to facilitate sensitive caregiving have been measured in both mothers and fathers. In mothers, distinct changes in the cerebral cortex (including regions linked to thinking about others minds) and subcortex (linked with emotion and motivation) have been measured - so much so that in a study conducted by Spanish researchers, an algorithm was able to readily distinguish between the brains of childless women and those of new mothers. Dads’ brains change too, with fathers demonstrating changes in regions of the cortex that contribute to visual processing, attention, and empathy toward the baby. Both are examples of what neuroscientists call experience dependent neuroplasticity (changes in the structure of the brain associated with specific life experiences). Here’s a lovely example of “Dad Brain” on display. If you can watch it to the end without tearing up you’re doing better than me. Dads will know the feeling.

It’s like looking in a mirror. 🪞 Check out the joint attention between this little one (10 weeks) and her big brother - who’s teaching an absolute master class in how to stimulate baby’s brain. I mean, are these two locked in or what? Brother is at baby’s level, up close, face-to-face and grinning from ear to ear. Their eye contact is unbroken. No distractions… just them. And he’s mirroring her vocalizations in a way that’s obviously thrilling for baby. Look at her face light up. It’s a great reminder that parents aren’t the only ones who can engage in serve and return interactions. Just beautiful. This sweet duo was shared to TT by gillianmccreery.

Steve Nash engaged in self-regulated learning early! His father, canny as a fox, pointed out what he did well and encouraged him to bottle the details. Remember this, remember that! Remember this, remember that! Memory - but it was never about remembering the performance outcomes, it was always performance process - the actions and decisions that helped the young Nash to score, not the scoring itself. All detail! All detail! This has been called attentional density (by neuroscientist David Schwartz). When you pay attention to something, your brain fires in patterns akin to that something. The more you think about it, the more the brain fires that way. The more the brain fires that way, the more chance you have of remembering what you’re paying attention to. Pay attention to the details! Pay attention to the details!

Want to keep your brain sharp and lower your risk of dementia? In this week’s episode, Dr. Tommy Wood (Tommy Wood MD, PhD) joins the podcast for a discussion on enhancing brain health and performance. Tommy, an M.D., Ph.D., is an expert in brain health, longevity, cognitive performance, concussion, and more. In this conversation, we discuss how dementia and late-onset Alzheimer’s disease are largely preventable through specific actions. Tommy shares in this clip that the risk of dementia and late-onset Alzheimer’s is drastically reduced by the extent of early-life education and how cognitively stimulating life remains afterward. The takeaway: Cognitive stimulation is crucial. The brain needs regular challenges throughout life. Early education is valuable, as is a mentally demanding job. However, if you don’t have these, be sure to read challenging books, learn a language, join a dance class, or practice jiu-jitsu. Do whatever it takes to challenge your brain—this stimulus is critical.

Knock off the negative self talk! Changing the words you say to yourself literally rebuild your brain in ways that help you or hurt you. Here's the science of one of the words you say to yourself matter: When you use criticizing language in your internal voice, your brain picks up on that and turns on the parts that are related to defending you from physical danger. Your brain hears your mind saying something harmful, and assumes that you're under attack. This affects your physiology, keeps you in a fight or flight response, and elevates your blood pressure and cortisol levels. In other words, when you attack yourself internally, your body gets the message and you literally feel like you're at war. On the other hand, research shows that when you use compassionate language to yourself, you don't magically make all your problems go away. What happens is that your brain area is related to problem-solving, calmness, and feeling hopeful, come alive. This set the filters in your reticular activating system to begin to look for possibility and not danger. The first commandment of self brain surgery is that I must relentlessly refuse to participate in my own demise. Using harmful words to yourself is literally committing malpractice against your own brain and your own life. So, and I say this with love, knock it off. Be kind to yourself. In a world full of difficulties, you deserve at least one ally. And your brain needs to hear encouraging language so I can do a better job of showing you a path forward instead of keeping you stuck. Jeremiah 29:11 says that God has a plan to give you hope and the future. Don't hinder his ability to do that by blocking your brain from being able to see what might already be there. Send this to a friend who needs an ally. Save this for the next time you find yourself feeling afraid. And follow me for connections between neuroscience and scripture every day that will help you flourish in your life. Click the link in my bio to learn more about my New York Times.

Experiments in progress. The one on the right has been learning for ~3 hours, the one in the middle for ~1 hour, and the one on the left just started a few minutes ago. The initial motivation for making the physical Atari was just to commit ourselves to a subset of algorithms that can make progress in this setup. This commitment rules out algorithms that require billions of samples to learn (or worse, require multiple environments running in parallel). Atari games are simple enough that we should be able to show learning on them in a short amount of time with no prior knowledge. Since then, I've realized that this setup is also a good way to compare different paradigms in robotics in a principled way. These paradigms are sim2real, learning from tele-operated data, and learning directly on the robots. So far, I have observed that getting sim2real to work reliably is hard. It requires tweaks that don't scale. Policies that can play perfectly in simulation fall apart because of latencies and the messiness of the real world. These aspects could be modeled to improve the simulation, but not without sinking significant human engineering hours. I have higher hopes for learning from tele-operated data, but that requires a human to learn the task first. These experiments are on my to-do list. I have to learn to play some of the games well through the robot. I’m half-decent at playing Pong and Ms Pacman now. Learning directly on robots is looking like the most promising approach. This approach takes away pesky distribution shifts and makes it possible to have algorithms that continually improve with more data and time without any human intervention. It feels great to let experiments run overnight and wake up to find improved policies. With learning on robots, I should, in principle, be able to go on a long vacation and come back to find better policies for complex tasks beyond Atari games. Whether that is possible with current learning algorithms is a different question.

Brain under construction! 🚧 🧠 🚧 Did you know that the period from prenatal to age three is the single most consequential window in all of human development? It is here that the fundamental architecture of the brain is “wired” in ways that will serve to support (or hinder) your child’s success for decades to come. At birth, your baby’s brain comes equipped with roughly 100 billion nerve cells, virtually all they will ever have. But what these cells must develop is the ability to communicate effectively with one another. They do this by transmitting electrical impulses. And there’s no time in life when these connections (known as synapses) are firing like they are during infancy. Scientists estimate that during the earliest years of life these neural connections are being made at a rate of one million per SECOND. Pretty impressive, huh? How can you help ensure your baby’s brain is optimally wired for success? Through attentive and nurturing interactions like the ones shown here. Every word you speak, every facial expression you convey, and every loving touch is helping to create important new connections. No one can be this attentive 24 hours a day. But prioritizing time to speak, sing, laugh, and play with your baby face-to-face is an investment you’ll never regret - and one that will serve them well for years and years to come.

New research confirms that physical activity plays a critical role in protecting brain health, reducing the risk of dementia, stroke, anxiety, depression, and sleep disorders. In contrast, prolonged sitting is linked to a significantly higher risk of these conditions. This study, based on data from over 73,000 participants, highlights the importance of movement as a modifiable factor for brain health.

Scientists discover surprising link between gut-brain interactions and mental health | Eric W. Dolan, PsyPost A new study provides evidence that the connection between the brain and the stomach may be linked to mental health in a measurable way. Researchers from Aarhus University in Denmark, publishing their work in Nature Mental Health, report that a specific pattern of communication between the brain and the stomach reflects how individuals feel emotionally and psychologically. Their findings suggest that these gut-brain interactions can indicate a person’s levels of anxiety, depression, well-being, and overall quality of life. The idea that emotions are linked to physical sensations in the gut is widely reflected in language. People often talk about having “butterflies in the stomach” when nervous, or feeling “sick to the stomach” when distressed. Yet, despite these common expressions, most scientific attention in the field of brain-body interaction has focused on other organs, such as the heart and lungs. These areas have long been studied for their roles in emotion and mood. The researchers were struck by how little was known about how the stomach, in particular, interacts with the brain. While recent studies have explored the influence of gut bacteria and digestion on mental health, very little work had been done on the electrical rhythms of the stomach and how they may directly communicate with the brain’s networks involved in emotion, attention, and cognition. The team behind this new study wanted to explore whether a person’s psychological profile might be reflected in how strongly the stomach and brain are coupled during rest. Their aim was not to link a specific diagnosis like depression to a single brain region, but rather to identify patterns across a broad spectrum of mental health experiences. “Our interest grew from the long-standing discussion about the role of the body in shaping emotion, a question that has fascinated philosophers and scientists for centuries,” said study author Leah Banellis (Leah Banellis), a postdoctoral fellow in Cognitive Neuroscience at Aarhus University. “Yet, while the heart and lungs have received much attention, the stomach has been largely overlooked. This gap struck us as especially surprising, because the link between the stomach and emotional experience feels so intuitive. It is heavily reflected in everyday language, with phrases like ‘butterflies in the stomach,’ ‘sick to our stomach,’ or ‘trust your gut.'” The research was part of the Visceral Mind Project, a large-scale initiative that combines data on brain activity, bodily rhythms, and psychological assessments. The team recorded data from 243 people using a method that captures both electrical signals from the stomach (electrogastrography) and brain activity measured with functional magnetic resonance imaging (fMRI). The participants represented a wide range of mental health profiles, from those reporting high well-being to others showing signs of distress, including anxiety, depression, fatigue, and insomnia. To capture this diversity, the researchers didn’t exclude people with psychiatric symptoms or diagnoses. Instead, they aimed for variation, which would allow their models to detect patterns across the mental health spectrum. Each participant underwent a series of recordings while lying still in the MRI scanner. At the same time, sensors on the abdomen captured the stomach’s slow electrical rhythm, which cycles about three times per minute. This rhythm, which originates from specialized cells in the stomach lining, is typically involved in coordinating digestion. But the researchers suspected it might also be linked to mental state. To analyze the relationship between stomach and brain activity, the team used a method that looks at how well the two rhythms align over time. This measure, known as phase-locking value, essentially captures the degree of synchronization between stomach signals and brain signals across different regions. The researchers then combined this data with results from a comprehensive mental health questionnaire. The battery included 37 different scores across a range of domains—such as anxiety, stress, mood, fatigue, attention, sleep quality, and life satisfaction. Using a statistical method known as canonical correlation analysis, they looked for patterns that linked brain-stomach coupling with the participants’ mental health profiles. The analysis revealed a clear and statistically significant pattern. Stronger coupling between the stomach’s rhythm and brain activity was associated with poorer mental health. Individuals who reported more symptoms of anxiety, depression, stress, and fatigue tended to show increased synchronization between their stomach and brain rhythms. In contrast, those with higher levels of well-being and life satisfaction showed weaker coupling. “For the first time, we’ve found a scientific link between your ‘gut feelings’ and your mental health, showing a surprising connection between your stomach’s natural rhythm and your brain,” Banellis told PsyPost. “Specifically, our study revealed that stronger communication between the stomach and brain is linked to worse mental health, such as higher symptoms of anxiety, depression, stress, and fatigue, whereas weaker stomach-brain communication aligns with better mental health reflected in higher overall well-being and quality of life.” This stomach-brain signature was not random. It was localized in specific brain networks, particularly those involved in attention, cognitive control, and salience detection. Some of the strongest associations were found in regions like the superior angular gyrus and the posterior frontal and parietal areas—regions often implicated in cognitive tasks and mental health disorders. Importantly, the researchers ran multiple control analyses to ensure the robustness of their findings. They ruled out the possibility that the observed effects were simply due to general brain activity patterns, fluctuations in heart rate or breathing, or basic features of stomach physiology. In other words, the association appeared specific to the coupling between the stomach’s electrical rhythm and particular brain networks—not just a general marker of body or brain state. Their approach was designed to detect broad psychological dimensions rather than focus on one diagnosis. The strongest psychological pattern they found was a spectrum ranging from negative affective states (like anxiety and depression) to positive traits (like well-being and quality of life). This result suggests that the stomach-brain connection is not tied to any one disorder but instead reflects a general mode of psychological functioning. “Anxiety, depression, stress, and fatigue showed the strongest links to stomach-brain communication,” Banellis explained. “While phrases like ‘butterflies in the stomach’ or feeling ‘sick to your stomach’ are common ways we describe emotional distress, it was surprising to find such consistent and clear evidence across these symptoms. Even more unexpected was the direction of the effect: we might have assumed that stronger alignment between the body and brain would be beneficial. Instead, our findings suggest that heightened stomach-brain communication could act more like a warning signal, an internal alarm system reflecting mental strain rather than harmony.” Read more:

Instead, they aimed for variation, which would allow their models to detect patterns across the mental health spectrum. Each participant underwent a series of recordings while lying still in the MRI scanner. At the same time, sensors on the abdomen captured the stomach’s slow electrical rhythm, which cycles about three times per minute. This rhythm, which originates from specialized cells in the stomach lining, is typically involved in coordinating digestion. But the researchers suspected it might also be linked to mental state. To analyze the relationship between stomach and brain activity, the team used a method that looks at how well the two rhythms align over time. This measure, known as phase-locking value, essentially captures the degree of synchronization between stomach signals and brain signals across different regions. The researchers then combined this data with results from a comprehensive mental health questionnaire. The battery included 37 different scores across a range of domains—such as anxiety, stress, mood, fatigue, attention, sleep quality, and life satisfaction. Using a statistical method known as canonical correlation analysis, they looked for patterns that linked brain-stomach coupling with the participants’ mental health profiles. The analysis revealed a clear and statistically significant pattern. Stronger coupling between the stomach’s rhythm and brain activity was associated with poorer mental health. Individuals who reported more symptoms of anxiety, depression, stress, and fatigue tended to show increased synchronization between their stomach and brain rhythms. In contrast, those with higher levels of well-being and life satisfaction showed weaker coupling. “For the first time, we’ve found a scientific link between your ‘gut feelings’ and your mental health, showing a surprising connection between your stomach’s natural rhythm and your brain,” Banellis told PsyPost. “Specifically, our study revealed that stronger communication between the stomach and brain is linked to worse mental health, such as higher symptoms of anxiety, depression, stress, and fatigue, whereas weaker stomach-brain communication aligns with better mental health reflected in higher overall well-being and quality of life.” This stomach-brain signature was not random. It was localized in specific brain networks, particularly those involved in attention, cognitive control, and salience detection. Some of the strongest associations were found in regions like the superior angular gyrus and the posterior frontal and parietal areas—regions often implicated in cognitive tasks and mental health disorders. Importantly, the researchers ran multiple control analyses to ensure the robustness of their findings. They ruled out the possibility that the observed effects were simply due to general brain activity patterns, fluctuations in heart rate or breathing, or basic features of stomach physiology. In other words, the association appeared specific to the coupling between the stomach’s electrical rhythm and particular brain networks—not just a general marker of body or brain state. Their approach was designed to detect broad psychological dimensions rather than focus on one diagnosis. The strongest psychological pattern they found was a spectrum ranging from negative affective states (like anxiety and depression) to positive traits (like well-being and quality of life). This result suggests that the stomach-brain connection is not tied to any one disorder but instead reflects a general mode of psychological functioning. “Anxiety, depression, stress, and fatigue showed the strongest links to stomach-brain communication,” Banellis explained. “While phrases like ‘butterflies in the stomach’ or feeling ‘sick to your stomach’ are common ways we describe emotional distress, it was surprising to find such consistent and clear evidence across these symptoms. Even more unexpected was the direction of the effect: we might have assumed that stronger alignment between the body and brain would be beneficial. Instead, our findings suggest that heightened stomach-brain communication could act more like a warning signal, an internal alarm system reflecting mental strain rather than harmony.” Read more:

Sam Altman on what you need to do to survive in the age of artificial intelligence. "You are about to enter the greatest golden age of human possibility..." To thrive in that world, the skills that matter most are: - Deep familiarity with the tools - Staying abreast of changes - Developing a great intuition for AI tools, where things are going, and how to make use of it - Resilience and the ability to learn things fast and evolve yourself with technology I know most of this stuff is a pretty big no-brainer for anyone paying attention, but here's the takeaway: AI upskilling and keeping up with AI are possibly the most important skills in the world right now. And the most fascinating part is that new AI developments and tools come out so fast that everyone is constantly learning. I'd be willing to bet that if you're a complete beginner but spend 3 months of dedicated learning, you'd be fully caught up to power users. In other words: Spend 3 months learning → work 2-4x faster and future-proof yourself. There's so much opportunity for anyone who just starts now.

The. Best. Want to nurture your baby’s early language? It’s really not rocket science, but it does take your time and attention. First, your baby is never too young to be spoken to. It may seem odd to have a conversational partner that can’t yet respond in conventional ways. But your baby is soaking your language up like a sponge. And never forget they learn language from YOU. Not a screen. Speak face to face with your baby. Make eye contact. Put down your phone and light up that developing brain 🧠. Talk, talk, talk. Engage, engage, engage. You’ll be amazed by the results - and you will have set your baby on the path toward a lifetime of success.

All the best coaching in the world at the youngest ages is rendered useless if a child hasn’t developed the ability to focus their attention. You can bring the best coach in the world to your child’s training session and if they don’t pay full attention absolutely nothing takes place. Similar to inside a classroom where you can bring the teacher of the year to your child’s classroom and if they don’t focus and pay attention, learning does not take place. So it’s not always the case of good or bad coaching it’s often the case a child’s lack of ability to learn by not focusing on what is being taught. This is especially true for the youngest ages. This video is an example of a 5yr old child focusing their attention, trying to control an object with their feet, the ball. This becomes a mental task, married together with the action of movement, making it a physical task as well. The brain loves to learn while moving. Combining, mind and body, thinking and feeling, this allows the cerebellum, the seat of the unconscious mind, to create a chemical signature of this experience, which is emotions. Emotions are the on off switch for learning. Couple in a parent being present, this becomes a shared experience together, where the child is constantly seeking the parents approval, attention, and praise which creates a chemical electrical process in the body which is emotions. This facilitates, deep learning, and long-term memory, all disguised as playtime. A parent just being present allows for this experience to take place. A child this young rarely starts playing or exercising with a ball without someone being present. Being present and sharing this experience together is key for the learning process to take place. These movements are being stored in the non-declared memory which makes this implicit learning when you do something so many times it becomes natural and outside your conscious awareness. Like riding a bicycle or driving a car.
