in somatosensory area of the brain what does this mean 'Each half of the body represented in the contra lateral cortex'

1 answer

In the somatosensory area of the brain, the statement "Each half of the body represented in the contralateral cortex" means that the sensory information from one half of the body is processed in the opposite (contralateral) hemisphere of the brain.

For instance, the left side of the body is represented in the right somatosensory cortex, while the right side of the body is represented in the left somatosensory cortex. This contralateral representation ensures that the brain receives and processes sensory information from the appropriate side of the body.
