Cortical measurements during active viewing. Observers performed the behavioral task while hemodynamic responses in retinotopic visual cortex were measured. a The average across observers of the αcon parameter, a measure of contrast sensitivity, is shown for each task context (dark and light markers are the contrast and coherence task, respectively). Inset shows how the change in the parameter affects the change in the contrast response function for V1, ignoring any change in additive offset. b As in a for coherence sensitivity, as measured by the linear slope of the coherence response function (dark and light markers are coherence and contrast task, respectively) and inset shows the relationship for MT. c As in a, b for the αtask parameter, which absorbs additive offsets. Inset shows the additive offset shift for MT
