Can electrical microstimulation be used to steer cortical population activity on- and off-manifold? Our new preprint says yes β€” using data-driven control in macaque PFC. Joint work with @gbarzon.bsky.social, Anandita De, Isaac Moran, Conner Carnahan, and Luca Mazzucato.

My review with @caterinagratton.bsky.social is (apparently) open access for those who couldn't see it before:

We discuss individual differences in brain network organization and how to home in on and talk about commonalities in the face of such differences

Unfortunately, today's talk at 11a EST by Dr. Mark Kramer is cancelled. Dr. Kramer will speak in Spring 2026. We will share the exact details as soon as they are confirmed. Thank you for your understanding. We look forward to sharing more valuable wave work with you in 2026!

Why do brain networks vary? Do these differences shape behavior? If every 🧠 is unique, how can we detect common features of brain organization?

Neuronal theta-phase locking increased during periods of elevated theta power, when aperiodic activity exhibited steeper slopes, and when clear theta oscillations were detected. Theta-phase locking was similarly strong during the successful and unsuccessful encoding and retrieval of memories. Some neurons changed their preferred theta phases between encoding and retrieval.
