Abstract
[3H]D-aspartate ([3H]D-Asp) and [3H]gamma-aminobutyric acid ([3H]GABA) have been used as “transmitter specific”retrograde tracers to identify projections to the mediodorsal thalamic nucleus (MD) that may use glutamate and/or aspartate, or GABA as their neurotransmitter. Following injections of the “nonspecific” tracer WGA-HRP into MD, retrogradely labeled cells are found in a wide variety of forebrain and brainstem areas, including layer VI of the frontal and agranular insular cortex, the thalamic reticular nucleus, the ventral pallidum (including the polymorphic zone of the olfactory tubercle), the deepest layers of the piriform cortex, periamygdaloid cortex and entor-hinal cortex, the amygdaloid complex, the superior colliculus, substantia nigra, and dorsal raphe nucleus. Following injections of [3H]D-Asp or [3H] GABA, different subsets of these cells are labeled.
