(8/8) To sum it up, event-based analysis powerfully captures the dynamics of gamma activity in the visual cortex. Gamma events support visual integration and occur at a flexible rate according to context and behavior. We look forward to seeing more developments of event-based analysis in the future

(7/8) Gamma event rate increases during visually guided responses and suppressing gamma events during a task decrease visual detection performance

(6/8) Most visually evoked spikes happen during gamma events! The more events you get during a visual stimulus, the more spikes you get as well

(5/8) Events are suppressed if we turn off the visual thalamus. Conversely events can be evoked by short activation of thalamic terminals

(4/8) Gamma events rate is modulated by arousal and locomotion. You get more events when a mouse is awake and active and more narrow band gamma power

(3/8) Narrow band power around 55Hz is caused by events patterning in bursts. Distributed events yield power in the broader gamma range (30-80Hz). So, gamma is an oscillation … but not always

(2/8) Using a new method: CBASS (github.com/cardin-higle...) we establish that gamma power can be linked to specific translaminar network events. Events can occur in oscillatory bursts or in isolation but maintain consistent dynamics throughout

(1/8) My latest study is out in @nature.com ! Kudos to coauthors especially @jess-cardin.bsky.social and to @kavliatyale.bsky.social and @wutsaiyale.bsky.social for support. We find that gamma power in mouse visual cortex is caused by brief events of visual processing www.nature.com/articles/s41...
