Summary: The study of defensive behaviors in predicting action outcomes in novel situations without trial and error is limited by the lack of appropriate animal models. Here, we present a protocol for preparing and using a delayed safety-seeking task

Summary: Animals are known to exhibit innate and learned forms of defensive behaviors, but it is unclear whether animals can escape through methods other than these forms. In this study, we develop the delayed escape task, in which male rats temporar

Abstract The balance between activities of fear neurons and extinction neurons in the basolateral nucleus of the basal amygdala (BAL) has been hypothesized to encode fear states after extinction. However, it remains unclear whether these neurons are

There has been a longstanding debate on whether original fear memory is inhibited or erased after extinction. One possibility that reconciles this uncertainty is that the inhibition and erasure mechanisms are engaged in different phases (early or lat

Fear renewal, the context-specific relapse of fear following fear extinction, is a leading animal model of post-traumatic stress disorders (PTSD) and fear-related disorders. Although fear extinction can diminish fear responses, this effect is restric

It is generally believed that after memory consolidation, memory-encoding synaptic circuits are persistently modified and become less plastic. This, however, may hinder the remaining capacity of information storage in a given neural circuit. Here we

'Fear neurons' in the basal amygdala (Ba) acquire excitatory responsiveness to conditioned stimuli (CS) after fear conditioning and are believed to encode aversive valence of conditioned fear. However, it is unclear whether identical fear conditionin

The myristoylated zeta inhibitory peptide (ZIP), which was originally developed as a protein kinase C/Mζ (PKCζ/PKMζ) inhibitor, is known to produce the loss of different forms of memories. However, ZIP induces memory loss even in the absence of PK

Fear renewal is defined as return of the conditioned fear responses after extinction when a conditioned stimulus (CS) is given outside of the extinction context. Previously, we have suggested that extinction induces S-nitrosylation of GluA1 in the la

Mechanisms underlying delay fear conditioning in which conditioned stimuli (CS) are paired and co-terminated with unconditioned stimuli (US), have been extensively characterized, thus expanding knowledge concerning learning and memory. However, trace
