Today I'm releasing the "1000×1000 collection": a unified place to learn about dynamical structure. 1000 simulated time series (1000 samples each) spanning 133 dynamical processes. Have a play? 🐛 #timeseries #dynamicalsystems #complexity #opendata dynamicsandneuralsystems.github.io/1000x1000/

How does the visual cortex coordinate neural activity over spatial and temporal scales? We found broad θ waves organize local γ bursts and spiking, forming a flexible spatiotemporal code to multiplex feedforward/feedback signals. Now out in full @natcomms.nature.com: doi.org/10.1038/s414... 🧵

📝 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! doi.org/10.1093/pnas... Authors: me, @mattjdavidson.bsky.social, and David Alais

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 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. Paper: doi.org/10.52294/001... Code (python/Matlab/C): github.com/DynamicsAndN...

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. arxiv.org/abs/2506.19800

@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. www.biorxiv.org/content/10.1...

📣🎉 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! 📣🎉 www.biorxiv.org/content/10.1...

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.

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. #criticality #complexsystems www.youtube.com/watch?v=4_rI...
