Adrenal responses to reinforcement and extinction: role of expectancy versus instrumental responding.

abstract：:Four experiments studied the opioid receptor subtype and signal transduction mechanisms mediating fear extinction in the ventrolateral quadrant of the midbrain periaqueductal gray (vlPAG). Microinjection of a mu- but not a delta- or kappa-opioid receptor antagonist into the vlPAG retarded extinction. Extinction was al...
