Don't be shy to take on a little two-week side project. These five months will be the most precious three years of your academic journey.

perhaps you could market some supplements and explain how they'll prevent ageing-related memory loss?

Another poster today at #cosyne26 (2-112)!

@rowanboard shows how early life social isolation alters dimension-based learning, cognitive flexibility, and the ventral hippocampus–PFC circuit.

Great collaboration with @jonroiser.bsky.social linking mouse and human versions of the task!

A screenshot of Google's AI Overview answer to the question "is haggis an animal". It says "Yes, the haggis is a small, furry mammal native to Scotland" and goes on to give the typical "asymmetrical legs" details.

Gotta say, did not have "Greece sends warships to defend island from Persian attacks" on my bingo card for this millennium, yet here we are.

it was always very obviously a graduate tax - during the era of tiny interest rates government could at least keep up the pretence that a decent chunk of people who do well in regular jobs would ever pay it off. Now interest rates have reverted towards historical norms that's impossible

Preprint alert!!! We recorded directly from the human ventral tegmental area (VTA), the principal source of cortical dopaminergic innervation, while patients performed an instrumental learning task. 🧵👇

Reminder: Haidt is not actually an "expert" in this field and actual experts have called out that he's just wrong about almost everything.

very disappointing - governments just love simplistic solutions to complex social problems. They could at least wait to see the impact in Australia

With some trepidation, I'm putting this out into the world:
gershmanlab.com/textbook.html
It's a textbook called Computational Foundations of Cognitive Neuroscience, which I wrote for my class.

My hope is that this will be a living document, continuously improved as I get feedback.

This paper had a pretty shocking headline result (40% of voxels!), so I dug into it, and I think it is wrong. Essentially: they compare two noisy measures and find that about 40% of voxels have different sign between the two. I think this is just noise!

there are a few connections it's important not to ignore - e.g. JLC chair is married to a right-wing influencer and councillor who just defected to Reform from the Tories

ah - I didn't notice that you adjusted for age. Was this based on mean age in each sample, or categorical?
