WebbThe receptive fields of the second ganglion cell type, organized in the opposite color cells yellow and blue, work in a similar way. The visual processing pathway from the retina to the cortex axons of the ganglion cells leave the optic apparatus at the blind spot of the retina and act as the optic nerve (optic nerve) initially to the optic nerve crossing (Optic chiasm). WebbMünch 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. cheap airline tickets to oakland california
