Campese, Vinn D.; Kim, Ian T.; Kurpas, Botagoz; Branigan, Lauren; Draus, Cassandra; LeDoux, Joseph E. – Learning & Memory, 2020
While interest in active avoidance has recently been resurgent, many concerns relating to the nature of this form of learning remain unresolved. By separating stimulus and response acquisition, aversive Pavlovian-instrumental transfer can be used to measure the effect of avoidance learning on threat processing with more control than typical…

Krypotos, Angelos-Miltiadis; Moscarello, Justin M.; Sears, Robert M.; LeDoux, Joseph E.; Galatzer-Levy, Isaac – Learning & Memory, 2018
Signaled active avoidance (SigAA) is the key experimental procedure for studying the acquisition of instrumental responses toward conditioned threat cues. Traditional analytic approaches (e.g., general linear model) often obfuscate important individual differences, although individual differences in learned responses characterize both animal and…

Martinez, Raquel C. R.; Gupta, Nikita; Lazaro-Munoz, Gabriel; Sears, Robert M.; Kim, Soojeong; Moscarello, Justin M.; LeDoux, Joseph E.; Cain, Christopher K. – Learning & Memory, 2013
Active avoidance (AA) is an important paradigm for studying mechanisms of aversive instrumental learning, pathological anxiety, and active coping. Unfortunately, AA neurocircuits are poorly understood, partly because behavior is highly variable and reflects a competition between Pavlovian reactions and instrumental actions. Here we exploited the…

Choi, June-Seek; Cain, Christopher K.; LeDoux, Joseph E. – Learning & Memory, 2010
Using a two-way signaled active avoidance (2-AA) learning procedure, where rats were trained in a shuttle box to avoid a footshock signaled by an auditory stimulus, we tested the contributions of the lateral (LA), basal (B), and central (CE) nuclei of the amygdala to the expression of instrumental active avoidance conditioned responses (CRs).…

Schiller, Daniela; Cain, Christopher K.; Curley, Nina G.; Schwartz, Jennifer S.; Stern, Sarah A.; LeDoux, Joseph E.; Phelps, Elizabeth A. – Learning & Memory, 2008
Fear responses can be eliminated through extinction, a procedure involving the presentation of fear-eliciting stimuli without aversive outcomes. Extinction is believed to be mediated by new inhibitory learning that acts to suppress fear expression without erasing the original memory trace. This hypothesis is supported mainly by behavioral data…
