Generative replay across hippocampal-neocortical circuits

To make flexible decisions, the brain needs to make inferences between events that were not directly experienced together. In sharp-wave ripple (SWR) events, during periods of rest and sleep, spiking ...

If an action results in error, each neuron requires an individualized teaching signal that guides change in its output. This is the credit assignment problem of learning. Are there neurons in the brain that can compute such a sophisticated teaching signal? Yes. www.biorxiv.org/content/10.6...

Climbing fibers encode the gradient of a loss function for the cerebellum

Neurons in the brain are often many synapses away from motoneurons, yet if a movement results in error, each distant neuron needs a teacher that considers its specific contribution to production of th...

Feeling incredibly honored to receive the William James Prize from the @theassc.bsky.social for our paper on how the brain distinguishes imagery and perception! Thank you to the committee and thanks @smfleming.bsky.social for being the best mentor!

Our new paper is out this week in Nature Neuroscience! www.nature.com/articles/s41... We built a BCI that works with the brain's natural geometry — and we found that people could learn to play a video game with their brains in <1 hr of training. This efficiency is groundbreaking & here's why:

New paper: "Introspection and Scientific Data" for the Handbook of Introspection, about the role of introspection in the production of scientific data. My view: introspection doesn't deliver a special 'subjective' kind of data and there's nothing special about studying consciousness.

This is unfortunately an issue that isnt going away I'm not against AI for science code implementation - apart from being faster it probably also just makes fewer mistakes than most PhD students (it's definitely better than me). The challenge is how (and in what form) to train people to oversee it

Nico Schuck@nicoschuck.bsky.social · 4mo ago

fully agree with Stefano. I spent years of my training learning to translate scientific thinking into models and code. if that’s no longer a bottleneck, what was the point — and what should replace it?

How does the brain build a memory? A common assumption is that the neurons activated during an experience collectively form the memory engram. In our new Nature Neuroscience paper (finally out!), we show that this is not the case. www.nature.com/articles/s41...

Deconstruction of a memory engram reveals distinct ensembles recruited at learning - Nature Neuroscience

Pouget et al. identified distinct CA1 neuron ensembles active during specific moments of fear learning and uncovered the core engram essential for memory formation.
