Sensory preconditioned and second-order conditioned responding are each well-
documented. The former occurs in subjects (typically rats) exposed to pairings of two …

Simple Summary Threat conditioning is a process by which animals learn about danger. As
such, this process has been extensively studied as a model of how humans develop fears …

Learning to associate cues, both directly and indirectly, with biologically significant events is
essential for survival. Second-order conditioning (SOC) involves forming an association …

How does a stimulus never associated with danger become frightening? The present study
addressed this question using a sensory preconditioning task with rats. In this task, rats …

The basolateral amygdala complex (BLA) and infralimbic region of the prefrontal cortex (IL)
play distinct roles in the extinction of Pavlovian conditioned fear in laboratory rodents. In the …

Associative learning is often considered to require the physical presence of stimuli in the
environment in order for them to be linked. This, however, is not a necessary condition for …

It is widely accepted that activation of NMDA receptors (NMDAR) is necessary for the
formation of fear memories in the basolateral amygdala complex (BLA). This acceptance is …

It is widely accepted that fear memories are consolidated through protein synthesis-
dependent changes in the basolateral amygdala complex (BLA). However, recent studies …

This study examined the effect of danger on consolidation of neutral information in two
regions of the rat (male and female) medial temporal lobe: the perirhinal cortex (PRh) and …

Consolidation of conditioned fear to a stimulus (S1) paired with shock requires de novo
protein synthesis in the basolateral amygdala complex (BLA), whereas consolidation of …
