Abstract
Adrenalectomy and dexamethasone blocking of adrenocorticotropin (ACTH) release in adrenalectomized and sham-operated rats did not affect time-dependent changes in performance following discriminated avoidance conditioning. Adrenalectomized rats also yielded the U-shaped intersession interval function characteristic of the Kamin effect in shuttlebox conditioning. The use of Sprague-Dawley rats precluded the possibility that time-dependent performance changes following aversive conditioning in adrenalectomized rats are the product of postoperatively developed accessory adrenal tissue. The Kamin effect occurs independent of pituitary-adrenal function.
