The cerebellum coordinates voluntary movements such as posture, balance, coordination, and speech, resulting in smooth and balanced muscular activity. It is also important for learning motor behaviors.
What happens if you damage your cerebellum?
Damage to the cerebellum, while not causing paralysis or intellectual impairment, might lead to a lack of balance, slower movements, and tremors (shaking). Complex physical tasks would become unsteady and halting. Last medically reviewed on January 21, 2018.
Is the cerebellum part of the brain?
It is a relatively small portion of the brain — about ten percent of the total weight, but it contains roughly half of the brain’s neurons, specialized cells that transmit information via electrical signals. The cerebellum is not unique to humans. Evolutionarily speaking, it is an older portion of the brain.
What part of the brain is responsible for a person's movement?

How many hemispheres does the cerebellum have?
The cerebellum is also divided into two hemispheres, like the cerebral cortex. Unlike the cerebral hemispheres, each hemispheres of the cerebellum is associated with each side of the body.
Why is the cerebellum important?
Although the cerebellum does not initiate movement, it does help to organize the movements to ensure it is a fluid and coordinated action . On their own, the frontal lobes would produce jerky, uncoordinated, and inaccurate movements, therefore the cerebellum plays an important part in regulating this.
What is the function of the cerebellum?
Functions. The cerebellum’s main role is to monitor and regulate motor behavior without any need for conscious awareness. The cerebellum’s main role is to monitor and regulate motor behavior among other functions . It was once believed that the only function of the cerebellum was in coordinating movements.
What percentage of the brain is the cerebellum?
Although the cerebellum only accounts for 10% of the overall brain mass, it contains over half of the nerve cells than the rest of the brain combined. The cerebellum is also one of few mammalian brain structures where adult neurogenesis (the development of new neurons) has been confirmed.
What are the three lobes of the cerebellum?
The cerebellum can be subdivided into three lobes that coordinate information received from the spinal cord and from different areas of the brain. The anterior lobe receives input primarily from the spinal cord. The posterior lobe receives input primarily from the brainstem and cerebral cortex. The flocculonodular lobe receives input from the cranial nuclei of the vestibular nerve. The vestibular nerve is a component of the vestibulocochlear cranial nerve. The transmission of nerve input and output signals from the cerebellum occurs through bundles of nerve fibers called cerebral peduncles. These nerve bundles run through the midbrain connecting the forebrain and hindbrain.

Which layer of the brain is responsible for processing information?
The folded outer layer of the cerebellum (cerebellar cortex) has smaller and more compact folds than those of the cerebral cortex. The cerebellum contains hundreds of millions of neurons for processing data. It relays information between body muscles and areas of the cerebral cortex that are involved in motor control.
What causes the cerebellum to become damaged?
The cerebellum may become damaged due to a number of factors. Toxins including alcohol, drugs, or heavy metals can cause damage to nerves in the cerebellum that lead to a condition called ataxia. Ataxia involves the loss of muscle control or coordination of movement.
What part of the brain controls movement?
The cerebellum helps us to have fine motor control while inhibiting involuntary movement. It coordinates and interprets sensory information in order to produce fine motor movements. It also calculates and corrects informational discrepancies in order to produce the desired movement.
Where is the cerebellum located?
The cerebellum and pons are located in the upper region of the hindbrain known as the metencephalon. Sagittally, the pons is anterior to the cerebellum and relays sensory information between the cerebrum and cerebellum. Cite this Article. Format.
What causes ataxia in the limbs?
Lesions of the intermediate part of the cerebellar hemisphere cause mainly ataxia of the limbs (i.e., appendicular ataxia) Ataxia is often caused by lesions of the cerebellar circuitry in the brainstem or other locations rather than in the cerebellum itself, which can lead to false localization.

Cerebellar connections involved in the lateral motor system are either ipsilateral or cross twice ( i.e. , “double crossed’) between the cerebellum and spinal cord
What is the superior cerebellar artery?
Superior Cerebellar Artery (SCA) Arises from the top of the basilar artery. In addition to supplying the cerebellum, these arteries course through the brainstem, providing blood to portions of the lateral medulla and pons. Of Interest: Infarcts are more common in the PICA and SCA than in the AICA territory.
What is the largest structure in the posterior fossa?
The Cerebellum . The cerebellum is the largest structure in the posterior fossa (see figures 15.1, 15.2, & 15.3). It is attached to the dorsal aspect of the pons and rostral medulla by three white matter peduncles and forms the roof of the fourth ventricle. It consists of:
Which is more common with SCA infarcts or PICA?
Infarcts that spare the brainstem and involve predominantly the cerebellum are more common with SCA infarcts than with PICA or AICA, therefore infarcts causing unilateral ataxia with little or no brainstem signs are most commonly in the SCA territory
What is the 2nd crossing of the spinal cord?
2nd crossing occurs as the corticospinal and rubrospinal tracts descend to the spinal cord. Inputs also follow this pattern, so each cerebellar hemisphere receives information about the ipsilateral limbs
