Fig. 2.
Examples of cell body and terminal labeling. A: Low-magnification photomicrograph of retrograde labeling in the contralateral PMv of case 1934 following injection of BDA in the ipsilateral PMv DFL. Numerous labeled cell bodies and fibers can be observed. The gray square indicates the area magnified in B. B: Cell body with multiple BDA-labeled dendrites (arrowheads). The long arrow points to the fiber that is magnified further (bottom). The many varicosities seen on this fiber (arrowheads) are typical of terminal bouton labeling in the present series of cases. C: Low magnification of FB-labeled cell bodies in the contralateral PMv of case 1892 following injection of FB in the contralateral PMv DFL. White square indicates the area magnified in D. D: Magnified FB-labeled cell bodies. Examples of protuberances considered to be dendrites are indicated by white arrowheads. Contrast and brightness of photographs were adjusted in Photoshop. Scale bar = 100 μm.
