Madary (2013) uses two sets of empirical results to show that representation of motion cannot be ascribed to MT simpliciter. One is the recent emphasis on spontaneous activity making significant contributions to the state of sensory systems—they add content referring to the attentional or sensorimotor state of the organism to input-derived sensory representations. The other demonstrates that in MT specifically, the response properties of cells can be quite variable and are not consistently related to perceptual content only.
