Form follows function!! Do you know functional neuroanatomy? This post will help you to remember the functional neuroanatomy you need to function if you are reading brain MRIs! Here’s how: 1. First start at the top —At the top you will see a gyrus that looks like a thumbs...

Are you agile on the sagittals?? Sagittal T1 images are for anatomy, but only if you know how to use them! Here is how I remember the sagittal anatomy 1. Start lateral 2. Find the gyrus that looks like a triangle, that is the pars triangularis of the inferior frontal gyrus 3. In front of it is the pars orbitalis—easy it’s over the orbit 4. Behind it is the pars opercularis. Remember oper sounds like OVER so its OVER the sylvian fissure 5. Behind the pars opercularis is the precentral gyrus 6. Right behind the precentral is the post central—duh post follows pre! 7. Behind the post central is the supramarginal gyrus. Remember supra means above, so it’s above the sylvian fissure. Margin = at the posterior margin of the sylvian fissure 8. Behind the supramarginal gyrus is the inferior parietal lobule. Remember inferior is below supra, so inferior parietal lobule is below the supramarginal 9. More medial is the lateral orbital gyrus. It’s easy, it above the orbit! 10. Even more medial is the gyrus rectus. Rectus means straight, so if you see a gyrus that is straight like a line, that is the gyrus rectus! Hopefully this gives you a handle on the sagittal! Stay tuned for the midline sagittal anatomy!!

Are you blind when it comes to occipital anatomy? This is a forgotten region, b/c vision isn’t considered eloquent. But it is still important to remember the anatomy! Here’s how, starting at the bottom —Lateral occipital gyrus It down at the bottom in the occipital lobe & lateral—simple one there! —Lingual gyrus It’s at the bottom and in the center, just like your tongue (lingual) is in the center of your mouth —Visual cortex Looks like two evil snake like eyes, staring at you from either side. So if you see eyes, it’s the visual cortex! —Parietal lobules Remember, Lobule and Lateral both start with L, so the lobules are lateral & stacked on each other —Cuneus and precuneus Remever, C is for central, so precuneus and cuneus are central in the midline! Hopefully, this post will back you up when it comes to the back of the brain anatomy!!

Does epilepsy imaging cause you to seize up in fear? Everyone knows mesial temporal sclerosis (MTS)! But did you know there are different KINDS of MTS?? This month's AJNR SCANtastic shows YOU what you need to know in the latest in epilepsy imaging! Here's what to remember: Hippocampus has 4 subfields w/CA abbreviation standing for “Cornu Ammonis”: CA1: Horizontal & ascends slightly. Number 1 on its side is horizontal w/a slight acsent! CA2: Superior hippocampal dome. Number 2 has a curve at the top that looks like a dome! CA3: Hippocampal curve ends & turns toward the dentate. Number 3 makes a curve heading down! CA4: Indistinguishable from the dentate. Number 4 on its side looks like CA4 being supported by the dentate underneath! Hippocampal sclerosis or MTS has 3 subtypes: Type 1 Classic form w/neuronal loss in all subfields Remember this rhyme: In type 1, hippocampus is all done! Type 2 CA1 predominant volume loss Remember this rhyme: Type 2 loses the glue! (CA1 glues the hippocampus to the rest of the temporal lobe) Type 3 is CA4 & dentate predominant volume loss Remember this rhyme: Type 3 loses the belly! CA4 & dentate are the hippocampus belly! Next time you have an epilepsy study, hopefully you'll seize the opportunity to use this! But this only scratches the surface! Follow AJNR & read the full article:

Hoover's neurological sign. Do you know how to perform it. We have been in neurology consults this week and we find this sign useful beyond organic from functional differentiation. Remember to utilize your contralateral hand under the ankle to help you gauge and understand the examination of weakness. It is pretty darn easy to slip your hand under the contralateral ankle.

Do you remember when the President of the United States could give a coherent, serious speech about immigration? If you don’t, this is what leadership used to sound like.

The more I think about it, the more I think this government is nuts. When you watch this video, remember that the government is supposed to work for you. You are the boss I talk about.

"I'll Be Over You" (1986) is one of those smooth 80s ballads that sneaks up on you. It is about trying to move on when the feelings are still there. Do you remember this one and the band's name? Is this one that you will listen to, or keep scrolling?

When are you starting your load? —Most of the games best hitters start there load & get into a ready position to hit before the ball leaves the pitchers hand. —Starting your load when the pitchers hand breaks is a good cue to go off of. Every single pitcher has to do this to throw the ball. Once there hand breaks every pitchers time to plate is close in timing. Giving you a consistent time to start. —Being on time towards the opposite field gap or through the middle for fastball. Gives you a chance to do damage on both pitches. The FB & Off speed. When you get into your advantage counts & have earned your fastball. 2-0, 3-0, 3-1. You can now then shift your sights over towards the pull side gap. —Hope this helps some people! #PlayerDevelopment

The commander of the TSabar Battalion, Lt. Col. M., addresses his fighters at the moment of leaving the Gaza Strip after two years of fighting. "Remember this moment, look at each other, see who is there by our side. In a second and a half, Sunday, Monday, Tuesday, the time will come and you will be at home. You will watch TV, tears in your eyes, and see people hugging their families, after more than 700 days without seeing them. When they ask you who did it, you will know that it was because of this group".

Break-Up Edition ❤️‍🩹 For/To: #Cancer #Scorpio #Pisces #WaterSigns You went above and beyond for this person and you just don’t understand none of this and why are things the way they are. This person fumbled you. For some of you, you get a front seat ticket to see all this person karma. Some of it has nothing to do with you but a lot of shit that caught up to them. The stories your about to hear. I got a particular message for someone that the one their with now, will he messaging you. Your gonna find it weird bc this karmic will be liking all your pictures and commenting and as soon as you check your message requests there’s a message. (Please update me if this has happened or does). Moral of the story this person is using the hell out of this karmic. Their in a place where they don’t know what they want. This person drinks and you end up getting brought up. When you left or they broke up with you, they left the greatest thing. I’m sensing a-lot of disappointment. I’m always hearing “if you think your lonely now, wait until tonight”. If this person has reached out, their sincere and they want you back. The more you stay away or shut them down it really triggers them. All this person can do is watch you move on. Some of you got what you wanted and laughing. It’s like this person is eating out the palm of your hand or soon will be. All that glitters isn’t gold. This person feels like a fool and having a major tower moment.
