Have submitted my application to neuromatch.social, I hope they accept me!

If they do I promise not to write posts that are too long!

Did nervous systems start out as simple circuits and only evolve to dynamic population modes as they got bigger? Or were the first neurons born into pre-existing "Hopfieldian" networks? http://www.wiringthebrain.com/2022/12/how-many-neurons-does-it-take-to-change.html
How many neurons does it take to change a lightbulb?

New platform, new #introduction

I'm a neuroAI researcher and neurotechnology consultant. I'm interested in the intersection of neuroscience and AI: what can AI teach us about how the brain works, and how can we use that knowledge to help people with neurological disorders thrive?

I've worked on this question in academia, in industry (Google, Meta) and in non-profits (Neuromatch). I write papers but some of my most high-impact writing is on my long-running blog, xcorr.net. I'm also the author of the good research code handbook, teaching students how to write code that doesn't bite back, goodresearch.dev.

Let's celebrate the season with a bit of science! Starting a daily countdown of 10 modern and fascinating ideas about the brain for us all to discuss. How likely is this to be true? And if true, what are the implications?

Brain idea 10: Our moods may depend not just on what's happening in our brain, but also our gut. The gist of the idea is that the gut can send distress signals to the brain that can trigger fear and anxiety.

The friendly summary:

The gut-brain connection - Harvard Health

The brain has a direct effect on the stomach, causing GI conditions. A person's stomach or intestinal distress can be the cause or the product of anxiety, stress, or depression....

New preprint from the lab. Ji trained mice on an interactive auditory task in which they control the frequency of a tone with a wheel. Imaging showed that neurons in A1 encode sound, action, and errors. Thus, A1 not only encodes sensory driven activity but also represents the complex interplay between sensory inputs, expectations, and errors. So much more to discover!

Older papers never cited???

Really good question about citation practices in #neuroscience and #psychology.

Established PIs have a responsibility to teach junior students to understand the history of the fields.

Asking again for good resources on 𝗵𝗼𝘄 𝘁𝗼 𝘄𝗿𝗶𝘁𝗲 𝘀𝗰𝗶𝗲𝗻𝘁𝗶𝗳𝗶𝗰 𝗽𝗮𝗽𝗲𝗿𝘀. More on the actual mechanics of it, not just the "top 10 rules" (which can also be useful), and especially online lectures. Anything come to mind?

#Introduction - My lab focuses on #olfactory system behavioral and #cognitive #neurophysiology. We do this in rats (mostly) and specialize in #NeuralOscillations as indicators of system states during cognitive sequences. I take a systems approach and my foundations are in dynamical systems.

I’m passionate about broad and deep scholarship and believe that scholarship is essential to progress.

I’m a proud graduate of #StJohnsCollege, Santa Fe #SJC, and view a classical education as one of the best things I’ve ever chosen to do (besides marrying my wife and raising our kids). My #liberalArts education informs every aspect of my scientific work.

Looks who's here!
Let's discuss Freeman soon please 😅
