I am very proud to announce that my PhD paper finally came out in Cell! In this *very* collaborative study, we develop and release a deep-learning approach to predict neuron type identity from their electrical signature. doi.org/10.1016/j.ce... 1/16 🧵

Fred Ramsdell was parked at a campground in Montana on Monday when his wife suddenly started shouting. He first thought that maybe she had seen a grizzly bear. Instead, she had regained cell service and had seen a flood of text messages with the same news. “You just won the Nobel Prize!” she yelled.
Winning a Nobel Prize Interrupted His Off-the-Grid Vacation
Fred Ramsdell found out about his Nobel Prize nearly 12 hours after it was announced because he was on vacation in the Rockies.

How does the brain decide? 🧠

Our new @nature.com paper shows that neural activity switches from an 'evidence gathering' to a 'commitment' state at a precise moment we call nTc.

After nTc, new evidence is ignored, revealing a neural marker for the instant when the mind is made up.

In neuroscience, we often try to understand systems by analyzing their representations — using tools like regression or RSA. But are these analyses biased towards discovering a subset of what a system represents? If you're interested in this question, check out our new commentary! Thread:
What do representations tell us about a system? Image of a mouse with a scope showing a vector of activity patterns, and a neural network with a vector of unit activity patterns
Common analyses of neural representations: Encoding models (relating activity to task features) drawing of an arrow from a trace saying [on_____on____] to a neuron and spike train. Comparing models via neural predictivity: comparing two neural networks by their R^2 to mouse brain activity. RSA: assessing brain-brain or model-brain correspondence using representational dissimilarity matrices

I really recommend sending your students to the Paris Spring School, many imaging and ephys techniques are covered in pretty good depth and the atmosphere is consistently fantastic every year! And in such a setting! parisneuro.ovh

Thrilled to share our state-of-the-art method for in vivo cell-type classification and brain region localization, NEMO, which is now now a spotlight at @iclr-conf.bsky.social !

We use NEMO to characterize the electrophysiological diversity of cell-types across the entire mouse brain. 🐭 🧪 🧠

How do we associate the flavors we experience during a meal 🍽️😋 with postingestive effects like food poisoning 🤢🤮 that arise much later?

Our answer in @nature.com this week: Illness signals from the gut reactivate and strengthen flavor representations in the amygdala.

Many of us use 2p scopes to image 3D volumes of brain. But then we analyze the data plane by plane, resulting in duplicated neurons, missed neurons, and low s/n. Let's go 3D!

First off, Bombcell is a MATLAB package (python version coming) developed by @juliefabre.bsky.social. It uses several metrics, like waveform shape, spike amplitudes and drift, to determine whether a detected unit is noise, multi-unit activity, axonal or a single neuron.

1/7 Our paper on individual variability in decision-making is finally out in @nature.com! Inspired by the classic work by Mante and Sussillo, we trained many rats to solve context-dependent decision-making, and we found that different brains use different neural mechanisms to solve the same task!

control is a complimentary approach to alignment.

its really sensible, practical and can be done now, even before systems are superintelligent.
