Interpretation of tail-pinch behaviors

Tail pinch versus brain stimulation: problems of comparison.

Tail pinch induced stress-arousal facilitates brain stimulation reward.

KATZ, R. J. AND K. ROTH. Tail pim'h induced stress-arousalfiwilitates brain stimulation reward. PHYSIOL. BEHAV. 22(1) 193-194, 1979.--Adult male Sprague Dawley rats with chronic access to self stimulation were sub~ctcd to handling, tail pinch, or left undisturbed. Tail pinch increased responding for positive reinforcement while the other conditions did not. The stress related properties of tail...

Tail pinch induces sexual behavior in olfactory bulbectomized male rats.

WANG, L. AND E. M. HULL. Tail pinch induces sexual behavior in olfactory bulbectomized male rats. PHYSIOL. BEHAV. 24(2) 211-215, 1980.--Adult male Long-Evans rats were subjected to bilateral olfactory bulbectomy, sham surgery or no treatment. Of 34 bulbectomized rats, 24 failed to ejaculate on either of 2 tests with a primed ovariectomized female. All control animals exhibited normal sexual beh...

Interpretation of “ Aberrant ” Drug - Related Behaviors

Diagnosis of opioid addiction in chronic pain sufferers is often triggered by occurrence of what have been called aberrant drugrelated behaviors. Ambiguities inherent in this approach affect patient care adversely. Rather than consistently signifying abuse or addiction, these behaviors are often motivated by undertreated pain. Appropriate clinical responses are suggested here, as well as a diag...

Tail pinch induces fos immunoreactivity within several regions of the male rat brain: effects of age.

Brief, intermittent stressors, such as low-level foot shock or tail pinch, induce a general excitement and autonomic arousal in rats that increases their sensitivity to external incentives. Such stimulation can facilitate a variety of behaviors, including feeding, aggression, sexual activity, parental behavior, and drug taking if the appropriate stimuli exist in the environment. However, the ab...
