| innominate substance | The region of the forebrain that lies ventral to the anterior half or so of the lentiform nucleus, extending in the frontal plane from the lateral preopticohypothalamic zone laterally over the optic tract to the amygdala (amygdaloid body); rostrally it tapers off over the dorsal border of the olfactory tubercle, caudally it ends where the internal capsule reaches the surface to form the cerebral peduncle or pes pedunculi. Notable among its polymorphic cell population is the large-celled basal nucleus of Meynert. These magnocellular elements within the substantia i. Are present in the medial septum and the diagonal band of Broca, but occur in largest numbers ventral to the globus pallidus. Histochemical evidence indicates that magnocellular elements distribute cholinergic fibres widely in the cerebral cortex and that these cells undergo selective degeneration in Alzheimer's disease. Synonym: substantia innominata. (05 Mar 2000) |
