      The cerebellum, located at the back of the brain underneath the cerebral hemispheres, is best known for its role in the control of movement. Despite its small size, the cerebellum contains more than half of the brain's neurons. These are organized in a repeating pattern in which cells called Purkinje cells receive inputs from two types of fibers: climbing fibers, which ascend into the Cited by: anesthetized rats.

Adult rats anesthesized with pentobarbital and injected intravenously with a mixture of [14C] sucrose and [3H] insulin were exposed for 30 min to an environment at an ambient temperature of 22, 30, or 40 degrees C, or were exposed at 22 degrees C to MHz CW microwave radiation at power densities of 0, 10, 20, or 30 mW/ by: The radiation emitted from mobile phones has various deleterious effects on human health.

This study was conducted to evaluate the effects of exposure to the MHz radiation electromagnetic fields (EMF) emitted by mobile phones on Ammon’s horn and the dentate gyrus (DG) in the hippocampus and cerebellum of male Wistar albino rats.

Twenty rats were divided into two groups i.e. control (n=10) and exposed (n=10). Animals were exposed with MHz frequency continuously for 2 hours a day for 35 days. The whole body specific absorption rate (SAR) was W/Kg. The mean ± S.E.M. body, whole brain and cerebellar weights of rats exposed to X-irradiation on PND 1 and their age-matched controls were shown in Table 1.

The cerebella of rats exposed to X-irradiation showed smaller and abnormal foliations compared with controls. Fewer cerebellar foliations due to fusion with neighboring folia were observed in folia I–III and VIa–VII. Cerebellar agenesis (subtotal cerebellar agenesis).

Rats exposed prenatally to ethanol showed a fusion of folia V and VI in the cerebellar vermis. Around the fusion, the cortical laminar structure was disrupted: Purkinje cell dendrites derived from each adjacent folium were tangled, and solitary or clustered ectopic granule cells were in the molecular by: Long-term exposure to a continuous MHz electromagnetic field disrupts cerebellar morphology in young adult male rats.

The occurrence of cerebral and cerebellar microgyria in a case of intrauterine infection possibly due to Toxoplasma gondii is reported.

A few aspects of two additional micropolygyric brains are briefly reviewed. The deep neuronal lamina in the 4-layered type of cerebral micropolygyria seems to be the equivalent of the normal isocortical infragranular stratum rather than an ectopic subcortical Cited by: Diffuse cerebellar atrophy can be difficult to distinguish from global cerebellar hypoplasia on a single study and can only be distinguished from the latter by demonstrating or implying (clinically) that there has been progressive change over time 9.

Diffuse atrophy can result from a variety of causes: alcoholic cerebellar degeneration. In another experiment the cerebellum of rats was exposed from birth onward to r on five successive days.

In the animals killed immediately or one day after the last radiation session the external granular layer was totally or subtotally eradicated. In the animals. Cerebellum Function.

The little brain or the cerebellum is primarily responsible for the motor faculties of the body. Though the cerebellum’s function is motor by nature, this also influences aspects like cognition and as well as helps initiate responses to fear and pleasure.

Rats in which the cerebellar output nuclei dentate and interpositus (DIN) had been ablated were exposed for 50 d to the H-reflex down-conditioning protocol.

DIN ablation, which in itself had no significant long-term effect on H-reflex size, entirely prevented acquisition of a smaller H-reflex.2 on the cerebellar cortex of male rats.

Dramatic morphological changes caused by E 2 were found on the Purkinje cells (including their dendritic tree) and in the cerebellar cortical layers. 48 Acta Veterinaria (Beograd), Vol. No. 1,Dreki} D et al.: Influence of estrogen on the cerebellar cortex of male rats Figure 3.The Cerebellar Cortex.

The cerebellar cortex consists of three layers: the molecular layer, the granule cell layer and the Purkinje cell layer in the middle. The input to the cerebellum comes via the mossy fibers and via the climbing fibers. Both of these are glutamatergic.
