When the dynamic noise is replaced with a homogenous field, a twinkling after effect (TwAE) is induced exclusively in the location of the former scotoma.

To analyze the loci within the visual system and the mechanisms of filling-in and the TwAE, we examined their orientation tuning, inter-ocular… CONTINUE READING
