Nucleus tuberomammillaris

from Wikipedia, the free encyclopedia

The nucleus tuberomammillaris is an extensive core area in the hypothalamus . The name is derived from the location between Tuber cinereum and Corpus mamillare .

The nucleus tuberomammillaris is the only nucleus of the central nervous system that produces the neurotransmitter histamine , and γ-aminobutyric acid (GABA) is also synthesized. The axons of the large-cell nerve cells in this core area project to the cerebral cortex . The main function is to increase awareness ( arousal ).

The nucleus tuberomammillaris is considered to be involved in the increased fatigue caused by antihistamines , as its functionality is reduced by drugs of this class of active ingredients.
