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

πŸ“ New Paper! πŸ“

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!

New paper!

We introduce an efficient set of statistical features for fMRI time series (calibrated on mouse manipulation experiments and tested on mouse and human data): catchaMouse16.

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.

@christopherjwhyte.bsky.social and I introduce a novel data-driven framework to evaluate >200 connectivity-based neural correlates of consciousness! Results are used to quantitatively compare predictions from neurodynamical models tailored to theoretic predictions.

Can't wait for #cosyne2025, starting tomorrow!

Our paper (with Leonardo Gollo and @bendfulcher.bsky.social) will be on display at poster [1-117]

Stop by 8pm to 11pm tomorrow and hear about our new method for detecting criticality in noisy systems like the brain!

First figure of our preprint, depicting brain maps of seven identified structural connectivity communities bridged by fifteen overlapping nodes at the spatial interface between communities. Structural communities are depicted as nodes on a circular graph while the overlapping regions between the corresponding communities are highlighted along the edges. The seven communities are: (1) Dorsomedial cortex; (2) Limbic; (3) Visual; (4) Ventral attention and visual stream; (5) Somatomotor; (6) Insula; and (7) Frontal pole.

πŸ“£πŸŽ‰ Excited to share work co-led with @aditijh.bsky.social, developing a data-driven selection technique for overlapping community detection algorithms, applied to the human structural connectome! πŸ“£πŸŽ‰

Higher-order connectomics of human brain function reveals local topological signatures of task decoding, individual identification, and behavior - Nature Communications Here, the authors perform a higher-order analysis of fMRI data, revealing that accounting for group interactions greatly enhances task decoding, brain fingerprinting, and brain-behavior associations c...

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, @lordgrilo.bsky.social, E Amico doi.org/nt34

Tracking the distance to a critical point in noisy systems
YouTube video by Dynamics and Neural Systems Tracking the distance to a critical point in noisy systems

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.
