classically conditioned defensive behaviors, commonly known as conditioned fear. These …

The last 10 years have witnessed a surge of interest for the mechanisms underlying the
acquisition and extinction of classically conditioned fear responses. In part, this results from …

Conditioned fear responses to a tone previously paired with a shock diminish if the tone is
repeatedly presented without the shock, a process known as extinction. Since Pavlov it has …

Over the course of natural history, countless animal species have evolved adaptive
behavioral systems to cope with dangerous situations and promote survival. Emotional …

It is currently believed that the acquisition of classically conditioned fear involves
potentiation of conditioned thalamic inputs in the lateral amygdala (LA). In turn, LA cells …

Resilience refers to the ability to successfully adapt to stressors, maintaining psychological
well-being in the face of adversity. Recent years have seen a great deal of research into the …

The authors recently showed that extinction of auditory fear conditioning leads to
potentiation of tone-evoked activity of neurons in the infralimbic (IL) subregion of the medial …
