cerebellum

 [ser″ĕ-bel´um]
the part of the metencephalon situated on the back of the brainstem, to which it is attached by three peduncles on each side (the cerebellar peduncles); it consists of a median lobe (vermis) and two lateral lobes (the cerebellar hemispheres). See also brain.

cer·e·bel·lum

, pl.

ce·re·bel·la

(ser'e-bel'ŭm, -bel'ă), [TA]
The large posterior brain mass lying posterior (dorsal) to the pons and medulla and inferior to the tentorium cerebelli and posterior portion of the cerebrum; it consists of two lateral hemispheres united by a narrow middle portion, the vermis.
[L. dim. of cerebrum, brain]

cerebellum

(sĕr′ə-bĕl′əm)
n. pl. cere·bellums or cere·bella (-bĕl′ə)
The trilobed structure of the brain, lying posterior to the pons and medulla oblongata and inferior to the occipital lobes of the cerebral hemispheres, that is responsible for the regulation and coordination of complex voluntary muscular movement as well as the maintenance of posture and balance.

cer′e·bel′lar (-bĕl′ər) adj.

cer·e·bel·lum

, pl. cerebella, pl. cerebellums (serĕ-belŭm, -ă, -ŭmz) [TA]
The large posterior brain mass lying dorsal to the pons and medulla and ventral to the posterior portion of the cerebrum; it consists of two lateral hemispheres united by a narrow middle portion, the vermis.

cerebellum

The smaller sub-brain lying below and behind the CEREBRUM. The cerebellum has long been thought to be concerned only with the coordination of information concerned with posture, balance and fine voluntary movement. Recent studies have shown, however, that the cerebellum functions to assist in many cognitive and perceptual processes. The cerebellum may also have a role to play in coordinating sensory input, and even in memory, attention and emotion.

cerebellum

the anterior dorsal (and largest) part of the HINDBRAIN which controls balance, muscle tone and the coordination of voluntary muscle. It is best developed in birds and mammals; in the latter there is a cortex of grey matter and the surface is complexly folded. The folds are lined with PURKINJE CELLS. Removal of the cerebellum unbalances an animal and affects the accuracy of voluntary movements such as walking, swimming, knitting.

Cerebellum

The part of the brain involved in coordination of movement, walking, and balance.

cer·e·bel·lum

, pl. cerebella, pl. cerebellums (serĕ-belŭm, -ă, -ŭmz) [TA]
The large posterior brain mass lying dorsal to the pons and medulla and ventral to the posterior portion of the cerebrum; it consists of two lateral hemispheres united by a narrow middle portion, the vermis.

Patient discussion about cerebellum

Q. can you recover after a cerebellar stroke?

A. You can recover after a cerebellar stroke but the process takes time and rehabilitation. With the right kind of rehab people reach great results, supposing of course the initial injury allows it.

Q. Is there any problem, if an arachnoid cyst ,2cmx1.5cm size, rostral to cerebellar region left untreated? symptoms: repeated headaches, twitching of muscles, tiredness

A. An arachnoid cyst that leads to symptoms usually needs treatment. Mild symptoms as you suggested are ok to left untreated however gradual onset of new symptoms may arise such as seizures, paralysis and other complications, therefore once symptoms occur one should consider treatment.

The cranial MRI displayed a weak residual hyperintensity in the right cerebellar hemisphere, probably as a residual indicator of the cerebellar bihemispheric hyperintensities described in the previous external MRI (Figure 1(b)).
Although cTBS applied to the left cerebellar hemisphere was slightly more effective than that applied to the right cerebellar cTBS, the difference between the two groups is not significant (all p > 0.05).
Adjusted analyses estimated for a unit (micrograms per deciliter) increase in mean childhood blood lead concentrations, a decrease of NAA and Cr concentration levels in the basal ganglia, a decrease of NAA and a decrease of Cho concentration levels in the cerebellar hemisphere, a decrease of GLX concentration levels in vermis, a decrease of Cho and a decrease of GLX concentration levels in parietal white matter, and a decrease of Cho concentration levels in frontal white matter.

Out of 14 SLE patients who had seizures, 9 had white matter hyperintensities; seven had isolated white matter hyperintensities, one had combination of white matter hyperintensities plus hyperintensities in corpus callosum and right middle cerebellar peduncle, and one patient had combination of white matter hyperintensities and hyperintensities in paramedian cerebellar hemispheres with mild brain atrophy.

Brain magnetic resonance imaging (MRI) revealed enlarged bilateral cerebellar hemispheres with evidence of hypointensity of the affected thoracic vertebral segment on T1 image and hyperintensity on the T2 image (Figure).
Rhombencephalosynapsis (RS) is a rare congenital posterior fossa malformation characterised by hypogenesis or agenesis of the vermis, dorsal fusion of cerebellar hemispheres, and fusion of the dentate nuclei and superior cerebellar peduncles [3].
Brain capillary telangiectasias are typically found in the pons, (1,2,4,5) but are also commonly located in the medulla, caudate nucleus, cerebrum, (3) cerebellar hemispheres, and in the spinal cord.
We did not observe macroscopical lesions in cerebellar hemispheres, in motor, or premotor areas.
Results: Abnormal T2-weighted hyperintense signals (indicating vasogenic oedema) were consistently present in the parietal or occipital regions in 5 (41.6%), but other locations were also involved, including the deep white matter in 3 (25%), frontal lobes in 1, inferior temporal lobes in 1, cerebellar hemispheres in 1, and basal ganglia in 1 (8.3% each).
