The description of an experiment in which electric stimuli were applied to different sensory fields of the cerebral cortex tends to support the theory that A. the simple presence of different cortical areas cannot account for the diversity of mental experience B. variation in spatiotemporal patterning of nerve impulses correlates with variation in subjective experience C. nerve impulses are essentially homogeneous and are relatively unaffected as they travel through the nervous system D. the mental experiences produced by sensory nerve impulses are determined by the cortical area activated E. variation in neuron types affects the quality of nerve impulses
