CBASS

Stages

1. 1.
   Discrete gamma event detection in V1(functional_characterization)

   This stage establishes the event-based analytical representation needed to study gamma activity that may not be well detected as oscillations.

   Selection: decompose patterned activity into discrete network events to track gamma activity

2. 2.
   Mechanistic interrogation of gamma event origin and function(confirmatory_validation)

   This stage links detected events to circuit mechanism and sensory encoding before behavioral claims are made.

   Selection: test whether gamma events synchronize firing, enhance encoding, and depend on dLGN input

3. 3.
   Behavioral validation of gamma event relevance(in_vivo_validation)

   This stage tests whether gamma events are not only physiological markers but also behaviorally relevant and causally effective in vivo.

   Selection: test whether gamma event rate predicts performance and whether suppressing or evoking events changes visual behavior

Steps

1. 1.
   Develop and apply the event-based analytical method to V1 activityanalysis method

   Detect discrete gamma events in patterned neural activity from mouse V1.

   Discrete event detection is needed before the authors can test how gamma events relate to encoding, circuit input, and behavior.

2. 2.
   Assess synchronization and visual encoding associated with individual gamma events

   Determine whether individual gamma events synchronize firing across layers and promote enhanced visual encoding.

   After events are detected, their physiological and encoding significance can be tested directly.

3. 3.
   Perturb dLGN to test thalamic control of V1 gamma events

   Test whether V1 gamma events are evoked by patterned dLGN input and suppressed by optogenetic modulation of dLGN.

   Circuit perturbation follows event detection to evaluate a mechanistic source for the events.

4. 4.
   Relate gamma event rate to visually cued behavioral responses

   Test whether gamma event rate rises before responses and predicts trial-by-trial performance.

   Behavioral correlation is assessed after establishing event detection and mechanistic relevance.

5. 5.
   Causally suppress or evoke V1 gamma events during behavior

   Test whether suppressing gamma events impairs visual detection and whether evoking them elicits a behavioral response.

   Causal manipulation is used after correlational and mechanistic evidence to test whether gamma events directly influence behavior.
