Parietalhirn

Parietalhirn, also known as the parietal lobe, is a region of the brain located near the center of the brain's hemispheres. It is part of the cerebral cortex, the outer layer of the brain responsible for controlling voluntary movements, processing sensory information, and managing thought and behavior.

The parietal lobe is divided into two main parts: the postcentral gyrus and the surrounding parietal cortex. The postcentral gyrus is the primary motor and sensory processing area, receiving and processing information from the body, particularly the skin and muscles. The parietal cortex, on the other hand, is involved in higher-order cognitive functions, including attention, spatial awareness, and memory.

Damage to the parietal lobe can result in a range of cognitive and motor deficits. These may include difficulties with spatial awareness, navigation, and recognizing and manipulating objects. In some cases, damage to this region can also lead to sensory processing issues, such as numbness, tingling, or burning sensations in the skin.

Research has also implicated the parietal lobe in certain neurological and psychiatric disorders, including Alzheimer's disease, frontotemporal dementia, and schizophrenia. In healthy individuals, the parietal lobe is thought to play a role in the integration of sensory information and the coordination of movements, particularly those requiring fine motor control.

Functional imaging techniques, such as functional magnetic resonance imaging (fMRI), have allowed researchers to study the parietal lobe's activity in greater detail. These studies have shed light on the complex interactions between the parietal lobe and other brain regions, contributing to a deeper understanding of human cognition and behavior.
