Relation between eating evoked by lateral hypothalamic stimulation and tail pinch in different rat strains.

چکیده
The similarity between the behaviors evoked by tail pinch (TP) and electrical stimulation of the lateral hypothalamus (ESLH) has been noted by many investigators. Evidence is presented for a possible inverse relationship between the probability that ESLH would evoke eating and the readiness to eat in response to TP in six different rat populations (High and Low lines of the LC1 and LC2 Hebrew University Strains, Sprague-Dawley, and Long-Evans). Discussion of these results emphasizes differences in intensity between ESLH and TP stimulation and differences in emotionality among rat populations.

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...

BEHAV. 26(3) 371-378, 1981.--Electrical stimulation of the lateral hypothalamus (ESLH) has been shown to produce individual response differences that cannot be attributed to the neuroanatomical locus of the electrode.

متن کاملLateral hypothalamus chemical stimulation-induced antinociception was attenuated by injection of dopamine D1 and D2 receptor antagonists in the ventral tegmental area
Introduction: Stimulation or inactivation of the lateral hypothalamus (LH) produces antinociception. Studies showed a role for the ventral tegmental area (VTA) in the antinociception induced by LH chemical stimulation through the orexinergic receptors. In this study, we assessed the role of intra-VTA dopamine D1 and D2 receptors in antinociceptive effects of cholinergic agonist, carbachol, m...
متن کاملAsymmetry in the effects of unilateral 6-OHDA lesions on eating and drinking evoked by hypothalamic stimulation.
The present experiment investigated the effects of unilateral 6-hydroxydopamine lesions of the caudate nucleus and nucleus accumbens on eating and drinking evoked by electrical stimulation of the lateral hypothalamus (ESLH). Lesions were made on either the 'dominant' or 'non-dominant' hemisphere as defined by an amphetamine-rotation test. We report here that lesions of the 'dominant hemisphere'...
متن کاملExcitatory connection from lateral hypothalamic self-stimulation sites to escape sites in medullary reticular formation.
Behavioral tests show that noncontingent stimulation of self-stimulation sites in the lateral hypothalamus increases escape and avoidance from central or peripheral stimuli. The present study investigated the possibility that this phenomenon was mediated by an excitatory connection from the lateral hypothalamus to neurons in aversive regions of the brainstem. Most of the 24 rats participated in...
