[Intrahypothalamic connections of the lateral hypothalamus].
Arkhiv anatomii, gistologii i embriologii, 1985Using the axon degeneration method by R. Fink and L. Heimer, organization of intrathalamic connections between various areas of the lateral hypothalamus have been studied after unisided electrolitic lesion. At any location of the injury foci, similar patterns are observed in ipsilateral distribution of degenerating fibers along the whole lateral ...

Comparison of electrolytic and ibotenic acid lesions in the lateral hypothalamus
Brain Research, 1985Electrolytic lesions in the lateral hypothalamus (LH) seriously affect ingestive behavior and sensorimotor functions in the rat. We here report that bilateral infusions of the neurotoxin, ibotenic acid (IBO) in the LH yield a decrease in body weight, but not to the same extent as electrolytic lesions. The sensorimotor impairments were most severe after

Conditioned flavor preference and aversion: Role of the lateral hypothalamus.
Behavioral Neuroscience, 2001Food-restricted rats with ibotenic acid lesions of the lateral hypothalamus (LH) and sham controls were trained to associate flavored solutions with positive or negative postingestive consequences. The LH rats learned to prefer a flavor that was paired with concurrent intragastric infusions of maltodextrin.

Functional heterogeneity of the monkey lateral hypothalamus in the control of feeding
Brain Research Bulletin, 1991Regional differences in the effects of electrical (ES) and chemical stimulation on execution of a bar-press feeding task, and in neuronal activity related to feeding, glucose sensitivity, and odor responsiveness were examined in the lateral hypothalamic area (LHA) of monkeys.

Electroencephalography and Clinical Neurophysiology, 1968
Abstract 1. 1. Bilateral and unilateral lesions were made in the ventro-medial nucleus of the hypothalamus of 124 male albino rats using techniques which cause a side effect of the deposition of metallic ions and techniques which do not have that effect. Bipolar recording electrodes were implanted bilaterally in the ventro-lateral hypothalamus.

A reevaluation of the role of the lateral hypothalamus in behavioral temperature regulation
Physiology & Behavior, 1987Rats exposed to the cold (-9 degrees C) were trained to depress a lever to obtain pulses of infrared heat. Half of the animals received bilateral electrolytic lesions of the lateral hypothalamus and half were sham operated. Lesioned and control animals performed similarly postoperatively and responded appropriately to changes in reward duration and ...

The Lateral Parabrachial Nucleus Inputs to the Lateral Hypothalamus Trigger Nocifensive Behaviors
NeuroscienceThe lateral parabrachial nucleus (LPBN) is known to play a key role in relaying noxious information from the spinal cord to the brain. Different LPBN efferent mediate different aspects of the nocifensive response. However, the function of the LPBN → lateral hypothalamus (LH) circuit in response to noxious stimuli has remained unknown.

The Lateral Hypothalamus, Catecholamines and Ethanol Self-Administration in Rats
1975The possible involvement of the medial forebrain bundle and the lateral hypothalamus in the maintenance, regulation and control of ethanol and morphine intake in animals received a fair amount of attention over the past five years. In what we believe to be the first study of this kind, Segal, Nerobkova and Rybalkina (1969) reported that electrical ...

Attack elicited in rats by electrical stimulation of the lateral hypothalamus
Physiology & Behavior, 1971Abstract Attack was elicited in normally non-aggressive rats by electrical stimulation of 53 points in the ventrolateral hypothalamus. Attack specificity tests disclosed that live mice, dead mice, and juvenile rat pups were attacked with significantly greater frequency, shorter latency, and longer duration than adult rats of either sex or guinea pigs,
