This study tests if opioid receptor blockade in the vlPAG affects avoidance learning in rats, finding no significant impairment in acquisition or performance.

This study examines how chronic restraint stress affects two active avoidance tasks in rats, finding impaired acquisition in two-way active avoidance but no effect on platform-mediated avoidance or extinction.

This study investigates whether safety signals in a two-way active avoidance task acquire reward-like properties by assessing their impact on avoidance learning and approach behavior in male rats.

This study investigates the effect of dopamine receptor blockade on avoidance learning in rats, finding that D1R antagonism acutely impairs avoidance but not long-term learning.

This study shows that overnight fasting reduces excessive avoidance and speeds fear extinction by decreasing brain activation in reward-related regions during threat omissions.

This study shows that the unexpected absence of threat activates human reward and salience systems similarly to reward prediction errors, with stronger responses to more probable and intense omissions.

This study uses fMRI to compare brain activity during safety learning via conditioned inhibition and standard safety signals, finding distinct cortico-striatal circuits for each.

This study shows scopolamine prevents context-dependent reinstatement of fear in rats after aversive experiences.
