gamma events

In behaving mice, gamma event rate increases before visually cued behavioral responses and predicts trial-by-trial performance.

Suppressing V1 gamma events impairs visual detection performance, whereas evoking gamma events elicits a behavioral response.

The relationship between gamma events and behavior is sensory modality specific and rapidly modulated by changes in task objectives.

Individual gamma events synchronize neural firing across layers and promote enhanced visual encoding.

V1 gamma events are evoked by patterned input from the dorsal lateral geniculate nucleus and are suppressed by optogenetic modulation of the dLGN, supporting a role in thalamocortical integration of visual information.

Gamma event rate in mouse V1 varies with arousal, and individual events can occur in brief oscillatory bouts or in isolation.
