dorsal pallidum
dorsal pallidum
The predominant portion of the globus pallidus in the striatopallidal system, which is defined by connectivity and neurochemical staining. The dorsal pallidum is distinguished from the ventral pallidum by a boundary that is partially defined by the anterior commissure. The remainder of the boundary is indistinct in sections stained for Nissl substance ( Heimer-1995 ).
