[Effect of hypothalamic stimulation on the appearance of the early and delayed responses of the somato-sympathetic reflex]. 1980

V A Skobelev, and O G Baklavadzhian

Stimulation of somatic nerves evoked in the cat L2--L3 white rami a late two--wave response. High frequency stimulation of the hypothalamus induced an increase of the blood pressure, facilitation of the first component and suppression of the second component of the late response. The components of the early response were insignificantly affected by the stimulation. The paired stimuli technique revealed interaction of descending and peripheral afferent excitation of sympathetic preganglionic neurons. The role of baroreceptor and hypothalamic excitation in spinal sympathetic mechanisms is discussed.

UI	MeSH Term	Description	Entries
D007031	Hypothalamus	Ventral part of the DIENCEPHALON extending from the region of the OPTIC CHIASM to the caudal border of the MAMMILLARY BODIES and forming the inferior and lateral walls of the THIRD VENTRICLE.

D007034	Hypothalamus, Posterior	The part of the hypothalamus posterior to the middle region consisting of several nuclei including the medial maxillary nucleus, lateral mammillary nucleus, and posterior hypothalamic nucleus (posterior hypothalamic area). The posterior hypothalamic area is concerned with control of sympathetic responses and is sensitive to conditions of decreasing temperature and controls the mechanisms for the conservation and increased production of heat.

D002415	Cats	The domestic cat, Felis catus, of the carnivore family FELIDAE, comprising over 30 different breeds. The domestic cat is descended primarily from the wild cat of Africa and extreme southwestern Asia. Though probably present in towns in Palestine as long ago as 7000 years, actual domestication occurred in Egypt about 4000 years ago.
