Question

Quizplus · Accepted Answer

The different body parts are not equally represented in the somatosensory cortex. The amount of cortical area devoted to a particular body region depends on the density and complexity of its innervation, meaning that body parts that are more sensitive or have more receptors will have a larger representation in the somatosensory cortex. This leads to a phenomenon known as somatotopic organization, where neighboring regions in the body are represented by neighboring regions in the cortex.
