A monkey attends to a stimulus left of fixation then to a stimulus right of fixation. If one were recording MT neuronal activity, it would reveal that
A) the neuron preferentially responding to the left stimulus is inactive when attending to the right stimulus.
B) the neuron preferentially responding to the left stimulus is unaffected by attention to the right stimulus.
C) the receptive field associated with the neuron responding to the left stimulus shrinks when attention shifts to the right stimulus.
D) the receptive field associated with the neuron responding to the left stimulus shifts right when attention shifts to the right stimulus.

The receptive field associated with the neuron responding to the left stimulus shifts right when attention shifts to the right stimulus. This is because attention modulates the activity of MT neurons, and when attention is shifted to the right, the receptive field of the neuron responding to the left stimulus will shift right in order to maintain its alignment with the attended stimulus.
