Taking courses on AI and consciousness. When we debate "where does consciousness begin in evolution?" I keep thinking of a single cell. It's already this complex, functional system that behaves in a way to actively exclude toxic stimuli from the outside environment.
I love this series from @thetransmitter.bsky.social, and also remember having such a strong impression from reading this paper in grad school. Even tiny parts of the cell are wildly crowded and complex! www.cell.com/cell/fulltex...

A new, Short and Sweet open-access paper on how briefly hiding the hand impedes goal-directed arm movements. Briefly is really brief: we find a decrease in performance in goal-directed movements due to just a few ms without vision of the hand (target remains visible). doi.org/10.1177/0301...

We (I and @willenjoy.bsky.social) created a toolbox for simulations of EEG/MEG because we needed to simulate data. Our initial aim was to simulate connectivity. For this short clip, I simulated two sources with phase connectivity using our toolbox.

This is a great idea except for the fact that it's wrong. You can obtain the same learning speed across dramatically different interstimulus intervals (T) as long as the intertrial interval (I) is kept in a fixed ratio with the interstimulus interval (Gallistel & Gibbon, 2000).

Wow, there are still new illusions to be discovered in vision!
A nice shift in perceived colour between central and peripheral vision. The fixated disc looks purple while the others look blue.
The effect presumably comes from the absence of S-cones in the fovea.
