Unlike @PessoaBrain, we argue that reductionism remains a valuable and viable approach to understanding brain function.
Like him, however, we suspect there is a better way (not emergence but expansion; preprint link to "Disentangling the brain w/ Srirangarajan)...

Hello Mastodon peeps 👋! This is what it looks like across hundreds of neurons in prefrontal cortex when a monkey starts dozing off.

I'm working with an organization that may eventually fund proposals to fund workshops for research groups working on "mathematics for humanity". This would include math related to climate change, democracy, economics, health, maybe AI risks, etc.

I can't give details until it solidifies.

However, it would help me to know a bunch of possible good proposals. Can you help me imagine some?

A good proposal needs these things:

@nataliepeluso @neuroscience That a rhythm as robust as breathing should help entrain brain activity, and thus play a functional role makes perfect sense. It probably helps that breathing rhythm is fast in mice (4Hz), and that olfaction is so important. I wonder if it still makes sense in human who breathe at a much slower rate (0.3Hz) and olfaction not as important. Thoughts?

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.

100% agree with that message.

Long time ago we saw in EEG recordings that the smallest change to the task changed everything about the results. Reduced experiments, with all their merits, stopped making sense to me on that day.

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.”

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) bmj.com/content/331/7531/1498

The case of the disappearing teaspoons: longitudinal cohort study of the displacement of teaspoons in an Australian research institute

Objectives To determine the overall rate of loss of workplace teaspoons and whether attrition and displacement are correlated with the relative value of the teaspoons or type of tearoom. Design Longitudinal cohort study. Setting Research institute employing about 140 people. Subjects 70 discreetly numbered teaspoons placed in tearooms around the institute and observed weekly over five months. Main outcome measures Incidence of teaspoon loss per 100 teaspoon years and teaspoon half life. Results 56 (80%) of the 70 teaspoons disappeared during the study. The half life of the teaspoons was 81 days. The half life of teaspoons in communal tearooms (42 days) was significantly shorter than for those in rooms associated with particular research groups (77 days). The rate of loss was not influenced by the teaspoons' value. The incidence of teaspoon loss over the period of observation was 360.62 per 100 teaspoon years. At this rate, an estimated 250 teaspoons would need to be purchased annually to maintain a practical institute-wide population of 70 teaspoons. Conclusions The loss of workplace teaspoons was rapid, showing that their availability, and hence office culture in general, is constantly threatened.

There seems to be an increasing use of the justification for a paper being "little is known". Here is the appearance of this phrase in PubMed. It looks like we know less as time progresses. Little is known about why this trend has developed.

⭐ 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....

Have you ever wondered what a head direction neuron looks like in a fly? Here’s an example where I patch-clamped a head direction neuron as a fly was walking around in a virtual-reality environment (sound on).

@theexplorographer@mindly.social @sfmatheson I am liking the Twidere app.

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...
