Amazing work led by Jingnan! Pooling in task and rest data can give us a lot of discovery potential like discovering hard to find networks in the thalamus (bulk of my postdoc work with Randy). Task data can be used to define networks and activations from left out runs can be investigated. Cool work!

Thank you @vaibhavtripathi.bsky.social for being an excellent first co-author!

2/2 - We also found that the larger the increase in connectivity between auditory and other WM networks, the better a person performed in the auditory WM task. But the same was not true for changes in connectivity with the visual network during the visual WM task.

TL;DR 1/2 - It's complicated! Although other explanations are possible, we suggest that auditory WM requires a larger degree of connectivity reorganization than visual WM because frontal auditory regions are not as well-connected to supramodal WM regions at rest.

Does anyone have a good go-to white matter tract atlas? I would love something analogous to Neurosynth but where you can input coordinates and get out white matter connectivity profiles/papers/etc.

Best I could find quickly so far is: dmri.mgh.harvard.edu/tract-atlas/

I just learned that there's a national graduate student crisis line - gradresources.org. Might be worth spreading the word as I'm pretty sure exactly *checks notes* zero grad students are doing well emotionally right now.

Excited to share this new preprint from the lab introducing a highly general spatiotemporal normalization modeling framework that handles continuous dynamic visual input. Beautiful work by Angus Chapman @afchapman.bsky.social Science continues!!

recently posted a new preprint (the first of my postdoc 🎉) where we implemented normalization across space *and* time, allowing us to capture several neural and behavioral findings! I'll be presenting this work at VSS in a couple of months too for those attending

A dynamic spatiotemporal normalization model for continuous vision
Perception and neural activity are profoundly shaped by the spatial and temporal context of sensory input, which has been modeled by divisive normalization over space or time. However, theoretical wor...

Are short-term memories just noisier versions of what we perceive? Are they fundamentally different? We (Chaipat Chunharas, @mjwolff.bsky.social, @meikehettwer.bsky.social and myself) delved into this in a paper out now in #elife: elifesciences.org/reviewed-pre.... For a quick summary, a 🧵 below:

Academic workers across the country are organizing to call on our congressional representatives on Thursday, 1/30, at 3pm ET / 12pm PT to demand these restrictions be lifted immediately.
There will be a training over zoom at the beginning of the event.
