Check out our new modelling paper, now on Biorxiv! We simulate how one can decode cortical alpha oscillations to identify memories by their unique temporal signatures, via some very cool binding and timing mechanisms.

"In HC, smaller ... vascular dilations in response to ... neuronal activity produce smaller positive BOLD signals. BOLD signals are therefore a less sensitive measure of neuronal activity in HC than in neocortex". Really important study for understanding hippocampal fMRI effects.

Freesurfers freeview works fine on Catalina and (almost) replaces tksurfer... except for making the cuts required for flatmaps. How do people create flatmaps these day?

We’re releasing new large datasets to accelerate including our first – and the world’s largest – dataset of brain activity gathered using , a high-resolution probe that can record activity from hundreds of neurons simultaneously.

New paper in Annual Review of Psychology, prior to publication. We examine functional specialization in the attention network, linking results from multiple methodologies. Functional contributions from each node change on a moment-to-moment timescale.

The hippocampal role in predictive actions changes over time (as indicated by a sharpening of task-based background connectivity to visual cortex). New paper by Hindy, Avery & Turk-Browne .
