But when firing rate to this motion direction is attenuated, why is it exactly the opponent direction which becomes perceptually salient? What's the mechanism? Like there must be some opponency mechanism for directions different by 180 degrees I guess? | |

| Jul 30, 2019 at 23:10 | comment | added | user234 | Ok thanks, but my question is not so much about the where (I am somewhat aware of MT and the dorsal stream, and that the size of the adapted area allows us to infer if it is a upstream inferred property or happens in MT itself), but why it is exactly the 180 degree opposite direction which then becomes perceptually salient, and not say the direction which is 32 degrees different. I am not sure if your answer addresses my question | |
