Excitation-inhibition balance as a framework for investigating mechanisms in neuropsychiatric disorders

VS Sohal, JLR Rubenstein - Molecular psychiatry, 2019 - nature.com
Abstract In 2003 Rubenstein and Merzenich hypothesized that some forms of Autism (ASD)
might be caused by a reduction in signal-to-noise in key neural circuits, which could be the …

An increase of inhibition drives the developmental decorrelation of neural activity

M Chini, T Pfeffer, I Hanganu-Opatz - Elife, 2022 - elifesciences.org
Throughout development, the brain transits from early highly synchronous activity patterns to
a mature state with sparse and decorrelated neural activity, yet the mechanisms underlying …

Criticality in the brain: A synthesis of neurobiology, models and cognition

L Cocchi, LL Gollo, A Zalesky, M Breakspear - Progress in neurobiology, 2017 - Elsevier
Cognitive function requires the coordination of neural activity across many scales, from
neurons and circuits to large-scale networks. As such, it is unlikely that an explanatory …

Consciousness is supported by near-critical slow cortical electrodynamics

D Toker, I Pappas, JD Lendner… - Proceedings of the …, 2022 - National Acad Sciences
Mounting evidence suggests that during conscious states, the electrodynamics of the cortex
are poised near a critical point or phase transition and that this near-critical behavior …

From mechanisms to markers: novel noninvasive EEG proxy markers of the neural excitation and inhibition system in humans

J Ahmad, C Ellis, R Leech, B Voytek, P Garces… - Translational …, 2022 - nature.com
Brain function is a product of the balance between excitatory and inhibitory (E/I) brain
activity. Variation in the regulation of this activity is thought to give rise to normal variation in …
