There are 11 primary sensory areas in the cerebral cortex.
They include the primary somatic sensory area, primary visual sensory area, and primary auditory sensory area.
These areas receive sensory signals from peripheral receptors and have spatial localization.
They only analyze simple aspects of sensations and cannot fully analyze complicated sensory patterns.
The primary motor area and Broca's area are also primary sensory areas.
Destruction of primary sensory areas can drastically affect the ability to utilize respective sensations.
The primary somatic sensory area represents different parts of the opposite side of the body.
The size of the area of representation is proportional to the number of specialized sensory receptors in each peripheral area.
The lips, face, and thumb have the largest representation, while the trunk and lower body have relatively small areas.
Primary sensory areas inform the brain that a sensory signal has arrived but cannot fully analyze it.
