Delayed accumulation of inhibitory input explains gamma frequency variation with changing contrast in an Inhibition Stabilized Network

The paper tests a hypothesis that delayed inhibitory input explains gamma frequency changes with contrast in a visual cortex model and confirms it with primate recordings.

Temporal characteristics of gamma rhythm constrain properties of noise in an inhibition-stabilized network model

The paper shows that OU noise in a Wilson-Cowan model replicates gamma rhythm dynamics and stimulus dependencies, suggesting constraints on neural noise properties.

Shape analysis of gamma rhythm supports a superlinear inhibitory regime in an inhibition-stabilized network

The paper analyzes the shape of gamma rhythm in V1 to determine the operating regime of inhibition-stabilized networks, finding a superlinear inhibitory regime is required to replicate the observed waveform.
