for undergrads getting their degrees this Fall: if u're computationally savvy & wants to get into cog neuro -- instead of taking up lab manager / RA positions, why not come to Korea & get a master's degree instead? it will be all paid for w/ stipend, of coz. why would u pay for a master's degree??

So happy to see this one out! We worked incredibly hard to wrangle data from these octopuses, and I'm so proud of Marie for pushing it all the way through to publication. 🐙

Excited to share that our paper on mirror use in octopuses is published today in @currentbiology.bsky.social! This is the first time mirror-mediated spatial navigation has been demonstrated in an invertebrate. 🐙 www.sciencedirect.com/science/arti...

Octopus bimaculoides can learn to utilize a mirror to localize a reward outside the line of sight

Mirror-mediated localization of hidden objects is well documented in vertebrates1,2,3,4,5,6,7,8,9,10,11,12 but has never been demonstrated in inverteb…

This is why you should only sign your nice reviews and submit the nasty ones anonymously

Spirit was a terrible airline and the fact they are shutting down is good.

Fellow tab hoarders, has anyone found a good method for closing large numbers of tabs while somehow remembering what they were and why you kept them open in the first place? Using open tabs as a to-do or to-read list has become unsustainable #academicsky

I'm honored to receive the Penn AI Fellowship with support from @upenndddi.bsky.social! The fellowship supports my research on computational models of perception and cognitive bias. Specifically, we want to understand when and why both brains and AI systems are susceptible to cognitive biases.

very excited to share some of the final bits of work from my PhD! 🎉 we find that phasic DA in the accumbens simultaneously tracks persistent motivation towards reward cues in addition to new learning (but maybe not RPE?!) in sign-tracking rats. check out the preprint below!
