Home > Nucleus (neuroanatomy)

In neuroanatomy, a nucleus is a central nervous system structure that is composed mainly of gray matter, and which acts as a hub or transit point for electrical signals in a single neural subsystem. For example, the lateral geniculate nucleus mediates signals in the vertebrate visual system. The vestibular nucleus stores head motion information and guides eye movements via the vestibulo-ocular reflex.

Other examples include the Raphe nucleus, which is involved in sleep, and the suprachiasmatic nucleus, which controls circadian rhythm. All the nerve cell axons terminating on a nucleus tend to employ the same neurotransmitter at their synapsenerve cells to communicate with one another through axons and dendrites, converting electrical signals into chemical ones. For the technology festival, see Synapse Festival. Synapses are specialized junctions through which cells of the nervous system signs. As a result, the effects of certain psychoactive drugThis article is about chemical substances. For other meanings of the word "drug", see Drug (disambiguation A drug is any substance that can be used to treat an illness, relieve a symptom, or modify a chemical process or processes in the body. The word "drs are concentrated in particular nuclei. MorphineSee Morphine (band) for the rock band. Morphine ( INN), the principal active agent in opium, is a powerful opioid analgesic drug. According to recent research, it may also be produced naturally by the human brain. Like other opiates, morphine acts directl is believed to act via synapses of the arcuate nucleusThe arcuate nucleus is a collection of neurons present in the hypothalamus. Some arcuate neurons contain dopamine and inhibit the release of prolactin by the pituitary. Other neurons contain neuropeptide Y (NPY) and affect hunger. When activated, these ne, for example.
