lillhjärnan

Lillhjärnan, also known as the cerebellum, is a major structure of the brain located at the back of the skull, beneath the occipital and temporal lobes of the cerebral cortex. It plays a crucial role in coordinating voluntary movements such as posture, balance, coordination, and speech, resulting in smooth and balanced muscular activity. It is also involved in motor learning, enabling individuals to perform a wide range of voluntary movements.

The cerebellum is composed of two hemispheres and is covered by the cerebellar cortex. It receives input from sensory systems and other parts of the brain and then integrates these inputs to fine-tune motor activity. Damage to the cerebellum can lead to various motor deficits, including ataxia, a lack of voluntary coordination of muscle movements. While its primary function is motor control, research also suggests the cerebellum has roles in some cognitive functions, such as attention and language. Its intricate neural circuitry allows for complex processing and adaptation of motor commands.
