WebMünch et al. (2009) examined the looming stimulus-evoked responses in PV-5 cells, which are OFF-responding, large ganglion cells. They strongly responded to an approaching motion, suggesting that these are the looming detector. However, unlike the looming detector in the insect eyes, the receptive field of PV-5 cells was not large. WebC. Ganglion cells are the true neurons of the retina. D.
