Abstract:
The afferent connections of the lateral hypothalamic nucleus in the rat werestudied with retrograde horseradish peroxidase(HRP)method using microinjection andmicroelectrophoretic technique.The microinjection syringe needle or microelectrophoretic pipette was insertedvertically into the brain or in inclined direction through the cerebellum.The results were as follows:Following HRP introduced into the lateral hypothalamic nucleus,labeled neuronswere found in the anterior hypothalamic nucleus,the paraventricular nucleus,thedorsal raphe nucleus,the locus coeruleus and substantia grisea periventricularis inall cases.In most cases,labeled cells were also observed within the lateral septal nucleus,the interstitial nucleus of stria terminalis,the medial preoptic nucleus,the lateralpreoptic nucleus,the supraoptic nucleus,the ventromedial hypothalamic nucleus,themedial and central amygdaloid nuclei,the nucleus reunius,the interpeduncular nuc-leus,the nucleus parabrachialis dorsalis,the nucleus parabrachialis ventralis,and thenucleus tractus solitanii.In a few cases,retrograde labeling of neurons was observed within the medialseptal nucleus,pars medialis of the nucleus medialis thalami,the supramammilarynucleus and nucleus raphe medianus.In certain cases,a small number of cells could be found in the dorsal tegmentalnucleus of Gudden and the nucleus dorsalis nervi vagi.Among those nuclei,the locus coeruleus,the supraoptic nucleus,the paraventri-cular nucleus and the dorsal parabrachial nucleus were labeled bilaterally.
