| Research Abstract |
It had already been reported that the retina had performed the motion anticipation, like a visual cortex. However, the mechanism to cause the motion anticipation in retina, not a brain, is not identified yet. Here, I used the optical illusion movie that has been used in the visual psychological research as a light stimulation to identify the mechanism. My electrophysiological and anatomical data suggest that the gap junction in retinal circuit should contribute to cause the motion anticipation in the goldfish retina. Interestingly, the several subtypes of retinal ganglion cells showed the same function. Canonically, we have believed that one retinal ganglion cell subtype had a one function. This research might provide the new concept in retina.
