This map of the somatosensory cortex shows distorted body parts because it indicates the amount of sensory cortex devoted to pressure and touch sensations from a specific body part. What can we assume about the body parts that are shown on the figure?
A)There is a direct relationship between size of the body part and the area on the somatosensory cortex.
B)There is an inverse relationship between size of the body part and the area on the somatosensory cortex.
C)There is a direct relationship between the number of receptors on the body part and the area on the somatosensory cortex.
D)There is an inverse relationship between the number of receptors on the body part and the area on the somatosensory cortex.
