The Parietal Lobe is located behind the frontal lobe and above the occipital lobe, separated from the frontal lobe by the central sulcus. Its primary involvement has to do with sensory processing, spatial awareness and body orientation, visuospatial attention and movement coordination, mathematical reasoning and symbolic processing, and integrating sensory information (e.g., combining touch and visual information to guide action
The Superior Parietal Lobule (SPL) is located in the upper part of the parietal lobe, above the intraparietal sulcus. Its functions include integrating somatosensory input with visual and motor signals (hand-eye coordination), understanding spatial orientation, and motion ring the position of the body in parts of space (proprioception)
The Precuneus is located on the medial surface of the cerebral hemisphere, tucked in an over the corpus callosum. Its functions include self-referential thinking, autobiographical memory and consiounous, and visual-spatial imagery and mental rotation. The precuneus is one of the most metabolically active brain regions.
The Somatosensory Cortex is located at the precentral gyrus, behind the central sulcus. Its function includes processing tactile information, and it is organized somatotopically, like the motor cortex.
The Inferior Parietal Lobule (IPL) is located at the lower part of the parietal lobe, below the intraparietal sulcus. Its functions include integrating sensory information, language processing, reading and writing, mathematical reasoning, spatial cognition, and understanding others’ thoughts and intentions. The IPL is organized through lateralization: the left IPL is involved in language and number processing, while the right IPL is involved in spatial attention and body awareness.
