Aperiodic 1/f noise drives ripple activity in humans - Nature Communications How aperiodic 1/f noise drives ripple activity in human brain and impacts on ripple detections is not fully understood. Here authors show that ripple detections should be driven by the 1/f noise, whic...

Ripple oscillations are central for memory and sleep.

But ripple detection in humans remains challenging. Here we introduce a simulation approach in @natcomms.nature.com as common ripple detectors mainly pick up 1/f noise and not genuine oscillations

Conjunctive population coding integrates sensory evidence to guide adaptive human behavior. New work led by @jonasterlau.bsky.social in @pnas.org. We used human intracranial EEG to understand how coordinated population activity supports context-dependent behavior. www.pnas.org/doi/10.1073/.... (1/4)

I think almost all scientific projects should be planned carefully. And I think an app can dramatically improve that. So I wrote an app for that (free for now, if you can fund this let me know). I tested it quite a bit (>8000 users in beta so far). try it: planyourscience.com

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 ...

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.
