In neuroanatomy, a nucleus (pl.: nuclei) is a cluster of neurons in the central nervous system, [1] located deep within the cerebral hemispheres and brainstem. [2] The neurons in one nucleus usually have roughly similar connections and functions. [ 3 ]
Solitary nucleus (Nucleus of the solitary tract) Respiratory center-Respiratory groups. Dorsal respiratory group; Ventral respiratory group or Apneustic centre. Pre-Bötzinger complex; Botzinger complex; Retrotrapezoid nucleus; Nucleus retrofacialis; Nucleus retroambiguus; Nucleus para-ambiguus; Paramedian reticular nucleus; Gigantocellular ...
The solitary nucleus (SN) (nucleus of the solitary tract, nucleus solitarius, or nucleus tractus solitarii) is a series of neurons whose cell bodies form a roughly vertical column of grey matter in the medulla oblongata of the brainstem. Their axons form the bulk of the enclosed solitary tract. The solitary nucleus can be divided into different ...
Perlia's nucleus, also known as nucleus of Perlia and abbreviated as NP, is a spindle-shaped nucleus located in the mesencephalon, a subdivision of the Edinger-Westphal nucleus [1] [2] situated between the right and left oculomotor nuclei. It is implicated in parasympathetic oculomotor functions, possibly including input to the iris and ciliary.
A cranial nerve nucleus is a collection of neurons (gray matter) in the brain stem that is associated with one or more of the cranial nerves. Axons carrying information to and from the cranial nerves form a synapse first at these nuclei .
The suprachiasmatic nucleus or nuclei (SCN) is a small region of the brain in the hypothalamus, situated directly above the optic chiasm. It is responsible for regulating sleep cycles in animals. [ 1 ] [ 2 ] Reception of light inputs from photosensitive retinal ganglion cells allow it to coordinate the subordinate cellular clocks of the body ...
The subthalamic nucleus (STN) is a small lens-shaped nucleus in the brain where it is, from a functional point of view, part of the basal ganglia system. In terms of anatomy, it is the major part of the subthalamus. As suggested by its name, the subthalamic nucleus is located ventral to the thalamus.
The midline nuclear group (or midline thalamic nuclei) is a region of the thalamus consisting of the following nuclei: . paraventricular nucleus of thalamus (nucleus paraventricularis thalami) - not to be confused with paraventricular nucleus of hypothalamus
