Excited to share my latest theory work on rodent maze navigation and reinforcement learning: biorxiv.org/content/10.110… inspired by a fascinating experiment from Matthew Rosenberg, Tony Zhang, Pietro Perona and Markus Meister.

New review from our lab Caltech Neuroscience : sciencedirect.com/science/articl…

Why does it take 10,000 trials to train a mouse on a trivial 2AFC task? When the same animal will learn a complex sequence of decisions in just 10 trials? I wrote a review with some speculations: sciencedirect.com/science/articl…. Also outside the paywall: arxiv.org/abs/2205.02075.

I have had this exact question for years but never found any reference that uses the word ‘complete’. The goal of asking this question is not to cast doubt on brain research but to try to understand the problem (how brains work) itself under some framework/theory.

Excited to share our latest work! 🎉 Individual-finger brain-computer interface decoding from posterior parietal cortex (PPC). #BCI finger representations resemble that of able-bodied individuals, even years after paralysis. elifesciences.org/articles/74478 #tweetprint 1/n:

Come see our poster at #SfN2022 about the search for magnetoreceptive neurons. Featured: zebra finches, zebrafish, and owls. Did we find a positive result? Come to the poster to find out! Presentation 551.09 Poster X7 Tue 2022-11-15 1-2 PM

How fast and how much can a mouse learn in two days? Here is our attempted answer🐭: youtu.be/ULZqNH9vWPA Come to see our #SfN2022 poster at 1-5 pm this Sunday 13th! (VV10, 237.06) Rogério Guimarães Markus Meister @PietroPerona

I realize I’m now forced to read tweets from Elon Musk although I am not following him.

An international BMB Caltech graduate student has been UNFAIRLY TERMINATED after reporting years of abuse, harassment, discrimination, & research misconduct of their PI. Over 400 Caltech students have signed a petition to demand the REINSTATEMENT of this graduate student.

Just finished reading "Models of the mind" by Grace Lindsay @neurograce. Learned many things! Recommended it as a companion to our mathematical neuroscience course. More comments in this blogpost markusmeister.com/2023/04/.

We're excited to share our latest work! We achieve SOTA results in segmentation, detection, and depth estimation, in single and cross-domain, by exploiting image-aligned text prompts in a pretrained diffusion backbone repurposed for vision tasks. See vision.caltech.edu/tadp/ 🧵👇

Hilarious prank! MIT students stealing Caltech branding for a fake university. Hey we're launching our own catholic school, and here's the logo. What do you think?

Fun fact: the date when it’s first posted on bioRxiv is my birthday.

This is unbelievable. How can a country that cares about the future begrudge $300 million to unlock the secrets of the mind and cure the most devastating ailments of the soul? This is 0.0035% of the federal budget. If you make 100k a year, this works out to $3.50. A coffee to

He will always be remembered first as a great mathematician.

🚨 Excited to present a poster & give a talk at #CCN2024 CogCompNeuro Massachusetts Institute of Technology (MIT) next week with Rogério Guimarães! Featuring our latest work with Markus Meister & @PietroPerona on the Manhattan Maze, including data from mice without cortex. Details: jieyusz.github.io/publication/ma…

Turns out it’s not just grad students—all human beings are slow.
