ar·cu·ate nu·cle·us of thal·a·mus

the small region of the ventral posteromedial nucleus of thalamus in which the fibers of the gustatory lemniscus and secondary trigeminal tracts terminate; it projects to the lower part of the postcentral gyrus of the cerebral cortex.

Flechsig areas - three divisions (anterior, lateral, posterior) of each lateral half of the medulla as seen on transverse section, marked off by the root fibers of the hypoglossal and vagus nerves.Flechsig fasciculi - fasciculus anterior proprius and fasciculus lateralis proprius.
