Why do our visual systems have “shortcut” connections (V1-V4)? What do they add beyond the classic hierarchical (V1-V2-V3-V4) pathway? 

The lab’s latest study takes activity flow modeling to the next level to answer this question, led by @alextzalav.bsky.social www.biorxiv.org/content/10.6... 1/n

Inspired by Edinburgh’s legacy of big ideas (e.g., Hume), on a train leaving the city, I crafted a proposal for a book about big ideas in network neuroscience—how brain activity flows generate representations that together compose our minds. The rest is history, and this new book: shorturl.at/3p100

Brain Flows

A pioneering theory of how brain network flows compose the neural symphonies that make us who we are

Our recent study, "Distributed cortical network dynamics of binocular convergent eye movements in humans" is out in Network Neuroscience, where we move beyond simple brain mapping to show that binocular convergence is driven by the flow of activity across distributed neural networks. 1/8

New online! Characteristics and mechanisms of cognitive impairment in Parkinson disease

Characteristics and mechanisms of cognitive impairment in Parkinson disease

Nature Reviews Neurology, Published online: 03 December 2025; doi:10.1038/s41582-025-01163-xCognitive impairment is one of a range of non-motor symptoms that people with Parkinson disease (PD) can experience in addition to the hallmark motor symptoms of the disease. In this Review, Oikonomou et al. outline the epidemiology and natural history of cognitive decline in PD and related disorders, and discuss the key underlying pathophysiological factors and mechanisms.

Excited to see our paper with @mwcole.bsky.social finally out in peer-reviewed form @natcomms.nature.com! We examine how the human brain learns new tasks and optimizes representations over practice…1/n

Lab’s latest is out in Imaging Neuroscience, led by Kirsten Peterson: “Regularized partial correlation provides reliable functional connectivity estimates while correcting for widespread confounding”, where we demonstrate a major improvement to standard fMRI functional connectivity (correlation) 1/n

Stories no one had heard in years…

Honored that a piece I wrote made it to NYTimes. It’s about how my mom’s stroke changed my connection to time, science, and nature. What a privilege to honor my mom in Modern Love. Below is a gift link. Let me know your thoughts 🙏🏼 www.nytimes.com/2024/12/20/s...

“Cognitive flexibility as the shifting of brain network flows by flexible neural representations”, a solo paper by yours truly, making the case that brain activity flow shifts are essential to mental flexibility (and quite interesting too!) Open access: www.sciencedirect.com/science/arti...

Lab’s latest at PLOS Comp Biol, led by Carrisa Cocuzza: “Distributed network flows generate localized category selectivity in human visual cortex”. This one changed how I think the brain works! Even "localized" functions are likely generated by distributed processes doi.org/10.1371/jour...

Distributed network flows generate localized category selectivity in human visual cortex

Author summary A fundamental question in neuroscience has persisted for over a century: to what extent do distributed processes drive brain function? The existence of category-selective regions within...
