Inverse brain localizations of d-aspartate and DAPOX. d-aspartate is concentrated in the olfactory bulb mitral cell layer, hypothalamus, anterior olfactory bulb, superior colliculus, the molecular layer of the cerebellum, and scattered nuclei in the brainstem. By contrast, DAPOX is concentrated in olfactory receptor neuron layer and glomeruli, hippocampus, cerebral cortex, thalamus, and cerebellar granule cells.
