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.

(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.

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.

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.

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.

In contrast, a study conducted on squirrel monkey cerebellum elaborating the effects of nonionizing radiations on Purkinje cells layer showed no significant change in thickness and density19.
This study is the first of its kind elaborating the comparison b/w the effects of 2G, 3G and 4G mobile phone radiations on the rat cerebellum. Previously, all the work that was done in this regard was focused on the effects of 2G and 3G radiations mainly.
From the discussion it can be clearly stated that mobile phone radiations have deleterious effects on the histomorphology of rat cerebellum with 4G radiations being the most hazardous.

A significant Purkinje cell loss was also observed in the cerebellum of STZ-induced diabetic rats, as evidenced by an analysis of the significant decline in the Purkinje cell density.
This study also found a lower number of cerebellar Purkinje neurons in the diabetic cerebellum, which was associated with decreased synaptic junction in the molecular layer.
Since the SYP protein has also been implicated in the synaptic vesicle biogenesis and release of neurotransmitters (Valtorta et al., 2004), it can be postulated that a diminished number of synaptic vesicles with reduced synapse maturation in diabetic rat cerebellum may also relate to the diabetes reduced SYP protein.
