 Figure Legend: Tuning of a neuron in MT showing a peak response in spiking rate at 0 degrees of motion. The dashed curve is generated when the animal is attending to the motion stimulus while it is in the receptive field (we shall not discuss the neural basis of attention, but see Wu 2014b, chap. 2, for a summary of the neuroscience of attention). The solid curve shows MT response when the animal is not attending to the motion stimulus in the receptive field. Figure from Lee &amp; Maunsell 2009.
