Periventricular nucleus - Wikipedia
The periventricular nucleus is a thin sheet of small neurons located in the wall of the third ventricle, a composite structure of the hypothalamus. It functions in analgesia. It is located in the rostral, intermediate, and caudal regions of the hypothalamus.
Periventricular Brain Region: Functions and Significance
2024年9月30日 · But wait, there’s more! The periventricular region is also home to several important nuclei – clusters of neurons that serve specific functions. One such example is the periventricular nucleus of the hypothalamus, which plays a crucial role in regulating our body’s circadian rhythms and stress responses.

2023年10月30日 · The periventricular zone is a very thin region of the hypothalamus that lies next to the midline, medial to the medial zone and borders the third ventricle. It mainly contains the periventricular nucleus .
The Periventricular Stratum of the Hypothalamus - ScienceDirect
This chapter discusses the anatomical studies and neurophysiological studies of the periventricular stratum (PVS) of the hypothalamus. The periventricular stratum consists of small neuronal cell bodies in a matrix of fine axonal processes and the bulk of the experimental evidence indicates that the posterior division of the PVS is not ...

2022年10月10日 · The hypothalamus is a bilateral collection of nuclei divided into 3 zones surrounding the third ventricle and the mammillary bodies. The nuclei in the periventricular zone generally regulate the endocrine system, and the nuclei in the medial and lateral zones regulate autonomic and somatic behavior.
Organization of the Hypothalamus - ScienceDirect
2015年1月1日 · Crosby and Woodburne (1940) recognized that the hypothalamus is best regarded as three distinct longitudinal zones (periventricular, medial and lateral) and this perspective is supported by physiological and behavioral analyses (Swanson, 1987). The periventricular zone contains most of the neurons that project to the pituitary and is therefore ...
The hypothalamic nuclei: Locations and major neuroendocrine functions
As depicted in Table 3.3, the periventricular zone contains four of the most important nuclei for neuroendocrine regulation: periventricular, suprachiasmatic nucleus (SCN), paraventricular nucleus (PVN), and arcuate. The periventricular nucleus is a cluster of small neurons, located at the wall of the third ventricle, which extend from the ...
Periventricular Nucleus - an overview | ScienceDirect Topics
The most medial part of each of the anterior–posterior divisions of the hypothalamus is the periventricular zone, bordering the wall of the third ventricle. At the level of the preoptic area, the organum vasculosum of the lamina terminalis is seen at the anteroventral end of the third ventricle, a vascularized area containing medium-sized ...
Hypothalamus and Nociceptive Pathways | SpringerLink
The hypothalamus includes about 40 nuclei of very different shapes and sizes. For simplification, it is generally divided into three medio-lateral zones, periventricular, medial and lateral and four caudo-rostral regions, mammillary, tuberal, anterior and preoptic.
the periventricular zone. The two nuclei lying along the ventral surface of the hypothalamus are the supraoptic nuclei. These magnocellular cell groups produce oxytocin and vasopressin. The nondistinctive cellular region between these nuclei is the anterior hypothalamic area, which controls thermoregulation and the secretion
