Journal of the Experimental Analysis of BehaviorREFLEXIVE FIGHTING IN RESPONSE TO AVERSIVE STIMULATION<sup>1</sup>
491 Citations1962Roger E. Ulrich, Nathan H. Azrin
Reflexive fighting was elicited between paired rats as a reflex reaction to electric shock prior to any specific conditioning, and under optimal conditions fighting was consistently elicited by shock regardless of the rat's sex, strain, previous familiarity with each other, or the number present during shock.
Physiology & BehaviorBidirectional effects of reinforcement shifts on pituitary adrenal activity
131 Citations1973Larry Goldman, Gary D. Coover +1 more
Two opposing effects on the pituitary adrenal system of shifts in amount of reward from that expected are revealed: a frustration effect-an increase in pituitARY adrenal activity as a result of a sudden decrease in frequency of reward, and an elation effect-a decrease in pituitsary Adrenal activity produced by a sudden increase in reward frequency.
Physiology & BehaviorPlasma corticosterone increases produced by extinction of operant behavior in rats
110 Citations1971Gary D. Coover, Larry Goldman +1 more
Results suggest that the pituitary-adrenal hormone system plays a role in extinction of appetitive behavior and show a major physiological change occurring as a consequence of extinction of an appetitive task.

98 Citations2008Stanford B. Friedman, Robert Ader
SciencePlasma Corticosteroids: Changes in Concentration after Stimulation of Hippocampus and Amygdala
97 Citations1963Arnold J. Mandell, Loring F. Chapman +2 more
Plasma 17-OH corticosteroid levels were determined before stimulation and at various intervals after stimulation in these limbic sites in patients in whom implanted electrodes had been placed during evaluation for surgical treatment of psychomotor epilepsy.
Brain ResearchEffects of amygdaloid stimulation on pituitary-adrenal activity in conscious cats
75 Citations1971G.Keith Matheson, Berrilyn J. Branch +1 more
The results provide information concerning the organization of the amygdala in its role as a modulator of pituitary-adrenal activity as determined by changes in plasma levels of cortisol and corticosterone.
NatureEffect of ACTH on Extinction of Rewarded Behaviour is blocked by Previous Administration of ACTH
47 Citations1971Jeffrey A. Gray
The two partial reinforcement effects are observed when an animal's response is rewarded or not rewarded in an unpredictable manner; both were blocked by 8 IU of ACTH injected during training only.
Progress in brain researchEffects of Steroids on Extinction of an Avoidance Response in Rats.: A Structure–Activity Relationship Study
44 Citations1970Tj. B. van Wimersma Greidanus
Progress in brain researchAnterior Pituitary Peptides and Avoidance Acquisition of Hypophysectomized Rats
36 Citations1970D. de Wied, A. Witter +1 more
The administration of adrenal maintenance doses of ACTH improves the rate of avoidance acquisition of hypophysectomized or adenohypophysectumized rats, and the heptapeptide ACTH had no effect on adrenal weight, plasma corticosterone, or thymus weight, indicating the absence of corticotropic activities.
Physiology & BehaviorMacrophotography of histological sections
23 Citations1971Sven O. E. Ebbesson, Kalman Rubinson
The procedures are very simple, and allow much more rapid and accurate qualitative and quantitative analysis of histological preparations.
