Model predictions of BOLD responses for orientation (in blue) and contrast (in green) conditions based on (a) on-target gain models of selective attention and (b) the optimal gain hypothesis with bilateral gain. Panels (c) and (d) show difference curves between the model predictions for attend-orientation and attend-contrast tasks in panels (a) and (b), respectively. Note that the model predictions show the greatest divergence at the cued orientation (0°) where gain is either maximized (panel c), or minimized (panel d).
