Synchronized Neural Activities: A Mechanism for Perceptual Framing
MetadataShow full item record
Variability in retinal and geniculate processing rate that is dependent on stimulus properties suggests that some later process can put parts corresponding to the same retinal image back into register. This resynchronization process is called perceptual framing. Here a neural network model of emergent boundary segmentation is used to show that synchronized cortical activities can subserve this role. Psychophysical results about the minimum delay between two visual stimuli that leads to the perception of temporal order can be explained and replicated with this model.
