What determines the pattern of working memory activity in the mouse cortex? We tackled this question in our new model of the mouse cortex and thalamus. This gives us a new cell-type-centric view on the specialisation of mouse cortical function @eLife elifesciences.org/articles/8… 1/9

Fantastic that there are now Books Upstairs in Books Upstairs. A real gem and an independent bookshop that deserves your support.
Books Upstairs is, hands-down, my favourite bookshop in Dublin. Even more so with their expanding second-hand section that makes them easily rival Shakespeare & Co of Paris. It is a heavenly winding space, and anyone who visits Dublin must come here. I always feel much better for having been through the doors and met Louisa and Maurice. Check out Louisa's trophy! 📚

What happens in the brain when a stimulus enters consciousness?
We built a biophysical model of the cortex to zoom in to synaptic interactions and zoom out to whole-cortex neural dynamics during perception.
It revealed a key mechanism for ignition🧵...

I feel this is a big step forward in our work modeling cortex-wide activity during cognition. Inspired by systems neuroscience and nonlinear dynamical systems, we propose a mechanism for interactions between the brain's major cognitive networks.
I am excited to share the last work of my postdoc as a Swartz Fellow at NYU on the dynamic routing of large-scale cognitive networks in the neocortex! 🌐🧠 Here's a quick breakdown below : 🧵

This work is inspired by work on cognitive networks by
@bttyeo , Bucker, Margulies, Spreng, work on communication subspaces by Semedo, Kohn, Machens, Yu, Kohn, and recent modelling work by Ostojic, @jmourabarbosa , @jorgefmejias and several others.
This is the fruit of an intense 3-year collaboration with
@ulisespereirao (who is the real driving force). It was guided thoughtfully by Xiao-Jing Wang. It has been a wonderful experience to think through problems with and learn from Ulises and XJ.

Please take the time to read this Open letter of psychologists and neuroscientists for peace in the Middle East — I signed it wholeheartedly, and so did thousands of fellow scientists.

Please consider signing this letter urging the international community to demand that Israel respect international humanitarian law and end the occupation of Gaza and the West Bank, and that all hostages and unduly imprisoned civilians are released: tinyurl.com/PsychLetter
Absolutely cracking paper by super team @DrBMunn @eli_j_muller @jmacshine . Down Under, Top of the World.
I am absolutely stoked to share our new study on multiscale neural dynamics across species and behaviour + network simulations exploring their benefits! The best lab going around! Captained by THE @jmacshine 🙌

Undergrads/graduates: if you want to do a PhD, can’t afford to do a masters and know the area you want to do a PhD in, a perfectly decent alternative is to apply for a research assistant job and gain substantial research experience. Check jobs.ac.uk for job ads

At #SfN2024 on Wed. 1:30 PM? Checkout the talk by (X-free) Chris Cueva who - w/ @anzahorodnii, @MendozaHalliday, N. Qian & B. Desimone - uses data and models to suggest that dynamic working memory representations help avoid interference from new inputs (2024.ccneuro.org/poster/?id=…).

not a Nobel but still pretty exciting to receive a New Innovator Award from the @NIH_CommonFund! We'll be using it to study the developmental origins of primate/human brain innovations @PrincetonNeuro. #NIHHighRisk
