Multiple context discrimination in adult rats: sex variability and dynamics of time-dependent generalization of an aversive memory

This study examines sex differences in memory generalization in adult rats across multiple contexts and timepoints, finding females better discriminators with lower fear responses than males.

Adolescent female rats undergo full systems consolidation of an aversive memory, while males of the same age fail to discriminate contexts

This study shows adolescent female rats undergo systems consolidation of an aversive memory, while adolescent males fail to discriminate contexts, with ovariectomy accelerating generalization in females.

Conflict-mediated tasks for studying the act of facing threats in pursuit of rewards

This paper develops three conflict-mediated tasks to study how rats balance threats and rewards, finding that low-dose diazepam facilitates reward-seeking despite threats.
