First ever public presentation of single cell evidence for non-spatial grid cells by Elena Gutierrez, Seb Veselic from Steve Kennerley lab. Steve an I have been dreaming of this moment for nearly 10 years. #sfn25

Choosing the best or avoiding the worst: complementary and opponent value signals in the human brain Whether the brain encodes the subjective value of pleasant and unpleasant situations via a single integrated circuit or through distinct pathways remains unresolved. It is also unclear how neural valu...

Structure in noise: Recurrent connectivity shapes neural variability to balance perceptual and cognitive demands in the human brain Does neural variability reflect random noise or a feature that benefits adaptive behavior? Using intracranial recordings in humans, Terlau et al. demonstrate that neural variability results from the r...

New work from the lab published in @cp-neuron.bsky.social by @jonasterlau.bsky.social and Jan Martini. We describe that trial-by-trial variability indexes recurrent connectivity across the cortical hierarchy, which supports reliable and flexible coding www.cell.com/neuron/abstr... (1/4)

A funny conversation with a newcomer at the contra dance in Woods Hole last night:
Me: What brings you to Woods Hole?
He: I’m a neuroscientist, working on octopuses.
Me: I’m a neuroscientist too! I study patches of human cortex that do ridiculously specific things.
He: Oh like that Kanwisher stuff?

New position, new social media account. After 5 fantastic years in Tuebingen, I moved to @yale.edu and the @wutsaiyale.bsky.social this summer - which means that I’ll be recruiting PhD students and postdocs. Please help me to spread the word and see current opportunities below 👇

Hippocampal stimulation reveals causal role of persistent neural activity in human working memory Working memory (WM) enables the temporary maintenance and manipulation of information, supporting flexible, goal-directed behavior. While converging evidence suggests that the hippocampus contributes ...

intracranial electrical stimulation on macro-electrodes & single-neuron recording from microwires. The sample size (N=30) is impressive. incredible work by Dr Jonathan Daume and Dr @urutisha.bsky.social and their colleagues.

A neural manifold view of the brain - Nature Neuroscience Recent advances in neuroscience have revealed how neural population activity underlying behavior can be well described by topological objects called neural manifolds. Understanding how nature, nurture...

Check out our new review/perspective (w/ @juangallego.bsky.social & Devika Narain) on neural manifolds in the brain! It was a lot of fun to think through these ideas over the past couple of years, and I'm excited it's finally out in the world!

Compositionality of social gaze in the prefrontal-amygdala circuits Each social gaze can be deconstructed into primitive components, including gaze content, social state, and gaze duration. To reduce dimensionality and facilitate generalization, the brain needs to rep...

Super excited to share this new work from the lab (led by Guangyao Qi)! We demonstrate compositional social gaze codes in the prefrontal-amygdala circuits, by testing three predictions from the compositionality hypothesis. 👇👇

The sycophantic tone of ChatGPT always sounded familiar, and then I recognized where I'd heard it before: author response letters to reviewer comments.

"You're exactly right, that's a great point!"

"Thank you so much for this insight!"

Also how it always agrees even when it contradicts itself.
