E) is not responsive to mechanoreceptors

Quizplus · Accepted Answer

The somatosensory cortex is responsible for mapping the distribution of somatic receptors (such as touch, pressure, temperature, and pain receptors) on the body.

Answer: E
 This statement is false as the somatosensory cortex is highly responsive to mechanoreceptors, which detect physical pressure or distortion.
