amygdaloid nucleus

a·myg·da·loid bod·y

[TA]

a rounded mass of gray matter in the temporal lobe internal to the cortex of the uncus and immediately anterior to the inferior horn of the lateral ventricle; its major afferents are olfactory and its efferent connections are with the hypothalamus and mediodorsal nucleus of the thalamus; it is also reciprocally associated with the cortex of the temporal lobe; it is subdivided into two major nuclear groups: basolateral and corticomedial. The individual nuclei of the amygdaloid body (or complex) are the basolateral amygdaloid nucleus [TA] (nucleus anygdalae basilis lateralis [TA]), basomedial amygdaloid nucleus [TA] (nucleus amygdalae basalis medialis [TA]), central amygdaloid nucleus [TA] (nucleus amygdalae centralis [TA]), cortical amygdaloid nucleus [TA] (nucleus amygdalae corticalis [TA]), interstitial amygdaloid nucleus [TA] (nucleus amygdalae interstitialis [TA]), lateral amygdaloid nucleus [TA] (nucleus amygdalae lateralis [TA]), medial amygdaloid nucleus [TA] (nucleus amygdalae medialis [TA]), and nucleus of the lateral olfactory tract [TA] (nucleus tractus olfactorii lateralis [TA]).

Synonym(s): amygdaloid complex [TA], corpus amygdaloideum [TA], amygdaloid nucleus, nucleus amygdalae
