The question whether midget bipolar cells in macaque monkey retina receive input from rods was investigated using double-label immunocytochemistry. Flat midget bipolar cells (labelled with antibodies against recoverin) were found to be pre- and postsynaptic to All amacrine cells (labelled with antibodies against calretinin). These results support physiological evidence that rod photoreceptor signals could reach the parvocellular pathway at an early stage of visual processing.
