A week in the life of the human brain reveals stable states punctuated by chaotic-like transitions.

Nature Communications June 5, 2026 Maxwell B Wang, Max G'Sell, James F Castellano et al.

Critical real-world neurocognitive processes, such as settling into a conversation and neurophysiological fluctuations, vary over minutes-to-days in real-world environments. We harnessed simultaneous multi-electrode intracranial and video recordings in twenty people during a week of unconstrained, spontaneous behavior. Using dynamical deep learning algorithms, we found neurodynamics linked to...

Differential cortical network engagement during states of un/consciousness in humans.

Neuron September 1, 2023 Rina Zelmann, Angelique C. Paulk, Fangyun Tian et al.

What happens in the human brain when we are unconscious? Despite substantial work, we are still unsure which brain regions are involved and how they are impacted when consciousness is disrupted. Using intracranial recordings and direct electrical stimulation, we mapped global, network, and regional involvement during wake vs. arousable unconsciousness (sleep) vs. non-arousable unconsciousness...
