Grant peer review costs a lot: ~$40k per application in reviewer time, with proposals reviewed again and again. In @thetransmitter.bsky.social , I propose a partial lottery: reviewers decide pass/fail, chance picks among the passes, and "unmissable" ideas and ECRs get protected routes.

🗓️ Join me on October 7 for one of the inaugural lectures of the Science of Intelligence Institute #UCBerkeley. Can we write scientific laws for intelligence? I believe that we can, that the math for it already exists, and that they apply across brains & machines. Let's chat: tinyurl.com/mvrfs39w

A few years of work behind this one. 🧠 The challenge isn’t just finding the right stim pattern. It’s understanding, predicting, and ultimately controlling the neural response between stimulation & perception No paywall: authors.elsevier.com/c/1nZjs3BtfH... We walk through the main results below 👇

Our lab is re-opening the search for a postdoc! The candidate we chose this round unfortunately had to withdraw (2-body problem). If you or someone you know is looking for a postdoc in ephys + spatial navigation + neurodegeneration, come check us out: aeryjoneslab.github.io
The Aery Jones lab is recruiting another postdoc! If you're interested in neural mechanisms of spatial memory, high-density recordings, cool tasks (like cricket hunting), and/or aging and Alzheimer's, come check us out: aeryjoneslab.github.io. Please pass along to your friends :D

Why did RNNs fail to learn long-term dependencies? What if we added one more modification, maybe now? It turns out we can give a pretty broad, analytical answer! See the attached paper for a rigorous treatment using centre manifolds, low-rank RNNs, and dynamical systems theory! go.aps.org/4fXWEeF
Why do neural networks undergo abrupt learning after training on memory tasks? New research traces this phenomenon to a “ghosting” mechanism that locks the system into a no-learning zone and proposes two practical fixes to address these pitfalls. 📝 https://go.aps.org/4fXWEeF
