We biology geeks may sound elitist when we use scientific names instead of common names, but we're really just trying to avoid this:

Remember, friends don’t let friends use the official Mastodon apps.

Get yourself Tusky for Android, or Metatext for iOS. Toot! Is also good for iOS.

Enjoy all the timelines and features.

Hey #neurodon #neuroscience #neurotech #neuro @neuroscience

Let's make it easier for new members of the Mastodon network to find the #neuroscience (and former #neurotwitter) community. Consider adding yourself to this list of neuroscience accounts on #Mastodon

Because this was my only post ever that got +5k likes on Twitter, it is only fitting that this is my first post here ⤵️

I created an awesome-PhD list on GitHub where everybody can contribute with their own tools and resources! 🔥

My Dad just sent this gem of a description of Zoom higher ed from 1927: “On the 201St Day of the year 3221 A.D., the professor of history at the University of Terra seated himself in front of the Visaphone and prepared to deliver the daily lecture to his class, the members of which resided in different portions of the earth. The instrument before which he seated himself was very like a great window sash, on account of the fact that there were three or four hundred frosted glass squares visible.”

I wrote a piece for the New York Times about how scientists used Twitter during the Covid pandemic and about what comes next.

As I clear up my Twitter history, there are some things I just don't want to lose. One is the Case of the Disappearing Teaspoons. (HT @synapticlee@twitter.com) https://www.bmj.com/content/331/7531/1498

⭐ Another new study showing the importance of #respiration to #oscillations #neuroscience- a little thread 👇

Wenyu Tu and Nanyin Zhang at Penn State University performed fMRI on sedated rats and combined the results with (1) measurements of the depth and rate of respiration, and (2) with electrophysiology to directly record the electrical properties of neurons. This allowed them to map out the network of neurons that become active in response to #breathing....

Intro time. Hi #sciencemastodon - I'm Co-Founder of the #preprint servers bioRxiv & medRxiv at Cold Spring Harbor Lab, where I also oversee CSH Perspectives and other #publishing projects. I trained as a molecular biologist. My goal is to improve science communication.

Learn more about bioRxiv at https://doi.org/10.1101/833400 - and on the podcast https://tinyurl.com/y8rbttwz

I'm also interested in promoting understanding of different career paths for academics. More at https://tinyurl.com/4papvn5z

You know how text models "naively" predicting the next words/characters led to breakthroughs in language & reasoning at scale?

I think this kind of prediction could do the same for visual reasoning...

YES. @jamesmharrison reminded me that "Inhibition is something that we DO".

But to tease apart dynamics of goal-directed activation amidst goal-directed suppression... especially when the goal may be unconscious or habitual in one instance, or skilled and volitional in another?

This new preprint may have the methodology needed to tease these things apart - "A mind-body interface alternates with effector-specific regions in motor cortex" 👇 https://www.biorxiv.org/content/10.1101/2022.10.26.513940v1

@neuroecology there seem to be various cross-posters, here is one: https://crossposter.masto.donte.com.br/
I'm not sure how it will really work given that often on twitter you're replying to an ongoing conversation ... I haven't tried it but post if you get to know it ...

Hi, this is Greta. You are welcome to follow me here, if you prefer planet earth to planet mars.

About 25 years ago, Crick and Koch wrote a very thought-provoking paper,

https://www.nature.com/articles/34584

It tries to answer the question, why do feedforward (FF) and feedback (FB) projections have such different properties in terms of terminating in different cortical layers and physiological impact — something that's ignored in many recurrent network models of cortex.

i.o.w.: Why do higher areas talk so differently to lower areas than lower areas talk to higher areas?
