The Periventricularnucleus is a thin sheet of small neurons located in the wall of the third ventricle, a composite structure of the hypothalamus . Functions in analgesia . It is located in the rostral, intermediate, and caudal regions of the hypothalamus . The rostral region aids in the production of both somatostatin and thyroid releasing hormone . The intermediate portion aids in production of thyroid releasing hormone , somatostatin , leptin , gastrin , and neuropeptide y . In humans and primates it also produces LHRH . Lastly the caudal region aids in sympathetic nervous system regulation, and is regarded as the rage center. It should not be confused with the paraventricular nucleus .

It can be subdivided into the lateral parabrachial nucleus and the medial parabrachial nucleus . The PBN connects the reticular formation to the thalamus thalamic relay nuclei as well as the intralaminar nuclei of thalamus intralaminar and related nuclei. Function In rodents, the PBN is the second relay nucleus in gustatory taste processing. Fibers from the nucleus of solitary tract connect to gustatory centers in the PBN, which sends projects along two pathways for taste processing. The first connects the PBN to the ventroposterior medial nucleus of the thalamus and the other connects the PBN to the central nucleus of the amygdala and lateral hypothalamus .

Unreferenced stub date December 2009 In neuroanatomy , a nucleus is a brain structure consisting of a relatively compact cluster of neuron s. It is one of the two most common forms of nerve cell organization, the other being layered structures such as the cerebral cortex or cerebellum cerebellar cortex . In anatomical sections, a nucleus shows up as a region of gray matter , often bordered by white matter . The vertebrate brain contains hundreds of distinguishable nuclei, varying widely in shape and size. A nucleus may itself have a complex internal structure, with multiple types of neurons arranged in clumps subnuclei or layers. The term nucleus is in some cases used rather loosely, to mean simply an identifiably distinct group of neurons, even if they are spread over an extended area. The Thalamic reticular nucleus reticular nucleus of the thalamus , for example, is a thin layer of inhibitory neurons that surrounds the thalamus. Some of the major anatomical components of the brain are organized as clusters of interconnected nuclei. Notable among these are the thalamus and hypothalamus , each of which contains several dozen distinguishable substructures. The medulla oblongata medulla and pons also contain numerous small nuclei with a wide variety of sensory, motor, and regulatory functions. In the peripheral nervous system , a cluster of neurons is referred to instead as a ganglion . Examples Brainstem red nucleus , vestibular nucleus , inferior olive Cerebellum dentate nucleus , emboliform nucleus , globose nucleus , fastigial nucleus Basal ganglia striatum caudate and putamen , pallidum globus pallidus , medial and lateral , substantia nigra , subthalamic nucleus Cranial nerve nuclei See also Brain Nervous system DEFAULTSORT Nucleus Neuroanatomy Category Neuroanatomy Neuroanatomy stub de Nucleus ZNS he ja pl J dro neuroanatomia pt N cleo neuroanatomia th ... more details
