📝 New Paper! 📝 We expanded on the perceptual oscillations found across the stride-cycle by comparing central and peripheral vision. Spoiler Alert: There's phase and amplitude difference between the visual fields!

Optimal phase for central and peripheral visual detection differs within the stride cycle
Abstract. It is important to investigate perception in the context of natural behavior in order to reach a holistic account of how sensory processes are co

New preprint! Why are long-range connectomic interactions in the cortex dominant in shaping dynamics in some experiments but apparently negligible in others? We (w/ R Maran,
@elimuller.bsky.social
) address this question by studying a new hybrid model of cortical dynamics.

Really happy to share that our latest work on "Higher order connectomics of human brain function" is now out in NatComms
@naturecomms.bsky.social
. One of the most fun projects that I've worked on! Big thanks to the friends involved F Battiston, M Lucas,

We're attempting to make short explainer videos to accompany our main published research papers. Here is the first, by Brendan, on our recent paper on tracking the distance to a critical point from a noisy time series.
