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 …

The developmental trajectory of functional excitation‐inhibition balance relates to language abilities in autistic and allistic children

H Plueckebaum, L Meyer, AK Beck… - Autism Research, 2023 - Wiley Online Library
Autism is a neurodevelopmental condition that has been related to an overall imbalance
between the brain's excitatory (E) and inhibitory (I) systems. Such an EI imbalance can lead …

Network hyperexcitability in early Alzheimer's disease: is functional connectivity a potential biomarker?

CJ Stam, AM van Nifterick, W de Haan, AA Gouw - Brain Topography, 2023 - Springer
Network hyperexcitability (NH) is an important feature of the pathophysiology of Alzheimer's
disease. Functional connectivity (FC) of brain networks has been proposed as a potential …

Changes in functional connectivity preserve scale-free neuronal and behavioral dynamics

A Rabus, D Curic, VE Ivan, IM Esteves, AJ Gruber… - Physical Review E, 2023 - APS
Does the brain optimize itself for storage and transmission of information, and if so, how?
The critical brain hypothesis is based in statistical physics and posits that the brain self-tunes …
