Term: Fundus of the striatum

Definition: The cytoarchitecture of this ventrolateral region of the striatum just deep to the substantia innominata is more heterogeneous than that of the nucleus accumbens and especially the caudoputamen. While the term fundus of the striatum (fundus striati of Heimer 1972) has been used here and there in recent literature, its borders have not been clearly defined, it is used here to refer to the region identified as the substriatal gray by Crosby and Humphrey (1941).

Nomenclature: Swanson-1998
