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 ]
Unlike the static nature typically depicted in textbooks, the plant cell nucleus is a highly dynamic structure, constantly moving around cells via actin networks and myosins. [1] The nucleus undergoes a characteristic program during cell division to guide asymmetric cell division, [ 2 ] but there are several stimuli that have been demonstrated ...
When administered, larger doses of ghrelin act centrally on the raphe nucleus, hippocampus, and amygdala which causes dramatic increases in food intake, memory retention, and increases in anxiety. The effects of ghrelin are seen on the raphe nucleus as soon as an hour after injection, suggesting rapid changes in the structure of the nucleus.
Nucleus (neuroanatomy), a cluster of cell bodies of neurons in the central nervous system; Nucleus that forms in the eye in nuclear sclerosis (early cataracts) Nucleus, a scientific journal concerned with the cell nucleus; published by Taylor & Francis; Nucleus, a small colony of honeybees, induced to raise a new queen by the beekeeper
The inferior olivary nucleus (ION) is a structure found in the medulla oblongata underneath the superior olivary nucleus. [1] In vertebrates, the ION is known to coordinate signals from the spinal cord to the cerebellum to regulate motor coordination and learning. [ 2 ]
The efferent bundle is constituted first of the ansa and lenticular fasciculus, then crosses the internal capsule within and in parallel to the Edinger's comb system then arrives at the laterosuperior corner of the subthalamic nucleus and constitutes the field H 2 of Forel, then H, and suddenly changes its direction to form field H 1 that goes to the inferior part of the thalamus.
The central nervous system (CNS) is the part of the nervous system consisting primarily of the brain and spinal cord.The CNS is so named because the brain integrates the received information and coordinates and influences the activity of all parts of the bodies of bilaterally symmetric and triploblastic animals—that is, all multicellular animals except sponges and diploblasts.
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 ...
