BME, XI., Stoczek u. 2., St. ép., 320.-as terem. April 28, Monday, 12:00-13:00 BME, Budapest, Stoczek u. 2, St. building, room 320. (H-1111) *Abstract: * Why does the phenomenal appearance of ambiguous patterns reverse spontaneously? What neural events precede and prompt these reversals? Of the two factors have been widely suspected -- attention and adaptation -- we can rule out the former and fail to find evidence implicating the latter. Surprisingly, we do find such evidence for a short-term memory of visual appearance. Perceptual states and memory states reverse independently and at widely different time-scales. Taken together, our results suggest that multi-stable perception (and perhaps phenomenal appearance generally) involves a close interaction of perceptual and memory levels.
