Top Highlights

• The illuminated trials had the arms pseudo-randomized, ensuring a balanced distribution of left and right sample arms (50% each), and restricted to allow a maximum of 3 consecutive trials.
• This indicates that the effect of hippocampal terminal silencing in RSC during TI trials affected interleaved NI trials, thus spreading beyond illumination.
• Furthermore, we asked whether our manipulation would prevent error-corrective behavior, in which animals use action-outcome information after an error trial (i.e., absence of reward),
• This observation suggests that such persistent disruption is caused by synaptic plasticity events related to preceding neural activity affected by the optogenetic manipulation
