It plays a particularly strong role in spatial awareness, as well as distinguishing between objects based on touch.

Full Answer

Some of the parietal lobe's functions include touch perception, visual input, self-transcendence and language and math.

When someone touches an object, the parietal lobe processes the resulting sensory input. This includes stereognosis, which is the art of identifying an object using touch and no other sensation. When a doctor uses two-point discrimination during neurological testing, a functioning parietal lobe helps the patient distinguish between the two points.

The parietal lobe manages the dorsal aspects of vision, which includes determining where an object is and spatial awareness. Different areas of the lobe contribute to this, and some work with other sensory inputs to deliver spatial awareness. For example, the ventral intraparietal area also uses auditory and vestibular input.

On the left and the right side, this area of the brain determines whether a person is spiritual, and how they are spiritual.

In terms of language and math, the left parietal lobe plays a role in their symbolic aspects. It also contributes to writing skills.
