Fig. 2.
Retinal distribution of DA varicosities. a–c: Confocal images of the mouse retina in three horizontal planes: (a) INL close to the IPL; (b) IPL close to the INL/IPL border; (c) proximal IPL close to the layer of ganglion cells. The six DA perikarya are seen in focus in (b) and out of focus in (a) and (c). Note the presence of DA varicosities at all three levels of the retina. DA, dopaminergic.
