Question

When Michael was a toddler, he lost his ring finger on his left hand in an accident. Now, as an adult, the somatosensory area originally associated with that finger:A)is associated with the ring finger on his right hand.B)responds to stimulation from his left middle and pinkie fingers.C)is withered due to nonuse.D)causes Michael to relive the painful accident when it is stimulated

Answer 1

Answer:

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.
