Allen Visual Behavior Change Detection Report

Single-session change-detection summary harmonized from the Allen Brain Observatory Visual Behavior open dataset. Hit and false-alarm rates are reported per session; aborted and auto-rewarded trials are excluded from rate calculations.

Caveats

Aborted trials (early licks before the change window) are filtered from rate calculations; they appear in outcome counts only.
Auto-rewarded trials are tagged in task_variables but are kept in the canonical table; they are excluded from hit and false-alarm rates.
Change-detection rates are reported per session without subject-level pooling; a multi-session aggregate is out of MVP scope.
