T-Maze Reward-Searching Task
Objective: To examine ensemble activity patterns in the ventral striatum during a reward-searching task on a T-maze and subsequent sleep/rest periods, and to investigate the relationship between ventral striatal firing patterns and hippocampal ripples

Protocol Steps
Pre-task sleep/rest period
Animals undergo an initial sleep or rest period prior to behavioral task
Note: This period serves as baseline before task execution

“During a reward-searching task on a T-maze, flanked by sleep and rest periods”
T-maze reward-searching task
Animals perform a reward-searching behavioral task on a T-maze while parallel recordings are made from ventral striatal ensembles and EEG signals are derived from hippocampus
Note: Parallel recordings from ventral striatal ensembles and hippocampal EEG are conducted simultaneously during task

Post-behavioral sleep period
Animals undergo sleep period following task completion for analysis of reactivation patterns
Note: Reactivation was especially prominent during post-behavioral slow-wave sleep
View evidence from paper
“reactivation was especially prominent during post-behavioral slow-wave sleep, but unlike the hippocampus, no decay in pattern recurrence was visible in the ventral striatum across the first 40 min of post-behavioral rest”
Post-behavioral rest period
Animals undergo rest period following task completion for analysis of reactivation patterns
Note: Unlike hippocampus, no decay in pattern recurrence was visible in ventral striatum across first 40 minutes
