🚨 New pre-print!! We built a miniaturized device with an array of 4 micro-cameras that can each image multiple cortical areas in freely behaving mice. The mini-MCAM can image dozens of brain regions spread across >30 mm^2 of the cortical surface

The arrayed approach allows linear scaling in size and weight of the device, as compared to cubic scaling if a single imaging element is used. To facilitate wide area imaging, we also had to innovate a new cranial window covering whole dorsal cortex.

This work co-led by Jia Hu and @cherkkil, with contributions from @kapilsa20700690 @IbrahimOladepo @DanielSurinach and several others past and present in our group. Has been a fun collaboration with @HorstmeyerLab

Saw this on last year's SFN and it was cool. Any of the students involved in this project considered a PhD or Postdoc position?

Thanks Weijian. I think you met @cherkkil at SfN. He will be on the lookout for positions in a year or so.

Today in nature, we report a spatial single-cell atlas of human cortical development, revealing surprisingly early specification of human cortical layers and areas. We built an interactive browser to explore the spatial data: Paper link below👇

My latest #neuro #visualization: An intuition pump on connectivity in the #brain ~75K #neurons in the #MICrONS mm³. I/O segregated by layers, function is columnar; the cortical column is the unit of cortical computation. A typical #pyramidal cell has over >10K input #synapses.

New art project: the concept is to carve an image into wood in a semi-abstract form that allows the viewer to both recognize and personalize the image. The image is carved as an array of precisely cut dimples in a piece of pale wood pre-coated with black paint. 1/7

🚨 New pre-print alert!🚨 Led by the brilliant, twitter-less post-doc James Hope. We built a 🤖 exoskeleton for 🐭🐁 so we can study their 🧠's as they go around navigating their world. An e.g., imaging 1000s of neurons in the cortex when mice walk an 8-maze. A 🧵

Kind of cool how we get a major step up in AI video every time image models improve. Insane work here with GPT Image 2 -> Seedance 2. Can't wait until we can each stream our own game like this 👀

Today we're sharing new research that brings us one step closer to real-time decoding of image perception from brain activity. Using MEG, this AI system can decode the unfolding of visual representations in the brain with an unprecedented temporal resolution. More details ⬇️

This is what our Osaka University team is developing in our Moonshot Internet of Brains Project. Unlike Synchron’s Stentrode, this technology can access thinner and more fragile cortical veins. By navigating into smaller vessels, it can record neural activity from a wider range of brain regions. So far, successful in pigs, and we aim to bring it to humans in the coming years.

TurboEdit Instant text-based image editing discuss: We address the challenges of precise image inversion and disentangled image editing in the context of few-step diffusion models. We introduce an encoder based iterative inversion technique. The inversion network is conditioned on the input image and the reconstructed image from the previous step, allowing for correction of the next reconstruction towards the input image. We demonstrate that disentangled controls can be easily achieved in the few-step diffusion model by conditioning on an (automatically generated) detailed text prompt. To manipulate the inverted image, we freeze the noise maps and modify one attribute in the text prompt (either manually or via instruction based editing driven by an LLM), resulting in the generation of a new image similar to the input image with only one attribute changed. It can further control the editing strength and accept instructive text prompt. Our approach facilitates realistic text-guided image edits in real-time, requiring only 8 number of functional evaluations (NFEs) in inversion (one-time cost) and 4 NFEs per edit. Our method is not only fast, but also significantly outperforms state-of-the-art multi-step diffusion editing techniques.

The human brain - the most fantastic organ system in the universe - it remembers everything you’ve ever seen, everything you’ve ever heard, can process more than 2 million bits of information in one second… it is the home of common sense.” -Ben & Candy Carson

Elon Musk says the vast majority of brain diseases are ultimately fixable with a Neuralink device "If you think of the brain like a computer, effectively like a circuit board, you can say if there were some short circuits or some circuits that should be there but aren't, we can fix those Basically, it's kind of like fixing a circuit board. The vast majority of brain issues, I think, are fixable with a Neuralink device. It’s a fine-grained way of reading and writing electrical signals in the brain at high precision If there’s an electrical storm like epilepsy, you can interrupt that storm. In the case of blindness, if somebody's lost their optic nerve or both eyes, you can still stimulate the visual cortex Anything that is a function of signals in or out, if that is the nature of the problem, it can be fixed ultimately with a Neuralink device."

An Italian tourist explains how women can swim in bikinis on the beaches of Jeddah... This isn’t a minor detail, but a direct result of the “manufactured openness” that’s crafting a new image of Saudi Arabia, an image that doesn’t reflect the identity of the Land of the Two Holy Mosques, nor its culture or values. It promotes a different reality, where entertainment is amplified... and the essence of the place is lost. #SaudiArabia

"People assume prototyping requires writing code, but Image Gen is simply much faster." Rohan (Codex PM) showed me exactly how he does it: "I took a screenshot of the Codex composer where you can type in a new message. Then I asked Codex to use Image Gen to prototype 4-5 ideas to improve project selection. I can then ask it to take the first image and make a prototype of it on a Codex site. We usually think of Image Gen as useful for things like turning my hair blue. But it can create amazing digital mocks too." 📌 Full episode:

I got early access to Runway's new Gen-4 References and it's incredible! Upload a single reference image to maintain consistent characters across scenes in multiple poses. You can prompt to continue in the same setting, focus on a specific area of the background, or match the color and tone. Here are some of my first results using the same character in different settings:
