Somatosensation plays a key role in human cognition

Takeaway

  • The somatosensory system plays a key role in high cognitive processing in humans.

Why this matters

    Using a novel approach, these findings extend Penfield’s homunculus to the higher level of somatosensory processing supporting a key role for somatosensation in human cognition. The unique distribution of body-part representations suggests distinct functional specialization of the four homunculi.
