Nancy Hicks · Answer 1

The correct option is B: responds to stimulation from his left middle and pinkie fingers

Explanation:

The human body has subcortical somatosensory neurons which reacts to stimuli based on modalities applied to a particular part of the body. From the case of Michael who lost his ring finger as a toddler, during adulthood the somatosensory area associated with the ring finger would cause a neuron receptive field around both the left and pinkie fingers.
