Loss of neuronal heterogeneity in epileptogenic human tissue impairs network resilience to sudden changes in synchrony

S Rich, HM Chameh, J Lefebvre, TA Valiante - Cell Reports, 2022 - cell.com
A myriad of pathological changes associated with epilepsy can be recast as decreases in
cell and circuit heterogeneity. We thus propose recontextualizing epileptogenesis as a …
