Topic: high gamma rhythm

Most brain functions rely on constant interactions among specialized brain areas. In primates, synchronized oscillations in distinct frequency bands have been suggested to facilitate the routing of feedforward and feedback signals across hierarchically organized visual areas. However, the underlying mechanisms remain largely unknown. Previous studies in mice identified two distinct visually induced gamma rhythms: a luminance-dependent narrowband high gamma rhythm (~60Hz) in both V1 and higher visual areas and a context-dependent low gamma rhythm (~30Hz) in V1. Our analysis of the open-source A
