Superior parietal lobule

The Superior parietal lobule (SPL) is a part of the brain located in the parietal lobe. It is bounded in front by the intraparietal sulcus, behind by the parieto-occipital sulcus, and underneath by the horizontal portion of the intraparietal sulcus.

Structure

The superior parietal lobule is involved in the processing of sensory information, and it plays a key role in the perception of spatial relationships between objects. It is also involved in the integration of sensory information from the visual system, the somatosensory system, and the vestibular system.

Function

The SPL is involved in a variety of cognitive functions, including spatial orientation, attention, and the manipulation of mental representations. It is also involved in the planning and execution of movements, particularly those that are guided by visual information.

Clinical significance

Damage to the superior parietal lobule can result in a variety of neurological disorders, including Balint's syndrome, Gerstmann's syndrome, and hemispatial neglect. These disorders are characterized by deficits in spatial awareness and the ability to perceive and interact with the environment.
