so if you cool v2 and then record in v1 so in activate feedback connections you actually would find that these surround suppression effects were themselves suppressed they go away if you take away the top-down feedback and this is a way easier experiment to do in in a network because you can just turn off the feedback connections and see what happens and lo and behold you get almost exactly the same pattern of feedback so in the pred net sit extent there surround suppression it's happening as a top-down feedback phenomenon just the
