Figure 1.

Computer reconstruction of a substantia nigra DA neuron stained by Lucifer yellow. A: Examined in a frontal plane, the DA neuron dendrites are observed to extend for hundreds of microns in the dorsal/ventral plane (top/bottom of figure) and in the medial/lateral plane (left/right of figure). B: However, examined from a dorsal viewpoint, the anterior/posterior extent of the neuron (top/bottom of figure) is highly compressed. (Pucak and Grace, unpublished observations.)
