In this science work there were conducted such researches as organometric, histological, immunomorphologic and morphometric of cerebellar cortex of 219 corpses of people (108 man and 111 woman) of young and old age. A comparative analysis of the parameters of bulb-shaped neurons in these ages revealed decrease of their height and width. It is found that distance between interval nerve cell bodies of ganglionic layer increases with age that obviously associated with progressing disorganization and death of bulb-shaped neurons. It is marked an increment in the number of immunopositive for glial fibrillary acidic protein, protide S-100 and vimentin astrocytes in granular layer and molecular layer of cerebellar cortex, and decline in the number of immunopositive for neuron-specific enolase and immunonegative for protide S-100 and vimentin bulb-shaped neurons that can be regarded as manifestation of neurodegeneration. Using immunohistochemical methods in research allows approaching more differentially to the issues of morphological assessment cerebellar cortex of elderly people and gives an opportunity to receive more objective and full information of postnatal morphogenesis.

α6-containing GABA receptors (α6GABARs) are strongly expressed in cerebellar granule cells and are of central importance for cerebellar functions. The cerebellum not only is involved in regulation of motor activity, but also in regulation of thought, cognition, emotion, language, and social behavior. Activation of α6GABARs enhances the precision of sensory inputs, enables rapid and coordinated movement and adequate responses to the environment, and protects the brain from information overflow.

Background: Essential tremor (ET) is the most common neurological movement disorder with few treatments and limited therapeutic efficacy, research into noninvasive and effective treatments is critical. Abnormal cerebello-thalamo-cortical (CTC) loop function are thought to be significant pathogenic causes of ET, with the cerebellum and cortex are common targets for ET treatment. In recent years, transcranial magnetic stimulation (TMS) has been recognized as a promising brain research technique owing to its noninvasive nature and safety.

Down syndrome (DS) is a genetic intellectual disorder caused by trisomy of chromosome 21 (Hsa21) and presents with a variety of phenotypes. The correlation between the chromosomal abnormality and the resulting symptoms is unclear, partly due to the spectrum of impairments observed. However, it has been determined that trisomy 21 contributes to neurodegeneration and impaired neurodevelopment resulting from decreased neurotransmission, neurogenesis, and synaptic plasticity.

Background: Maternal folate usage is essential for neurodevelopment, but its effects on cerebellar structure are unclear. Cerebellum undergoes a protracted period of development, making it sensitive to maternal nutritional imbalances. Astrocytes are necessary for cerebellar cortex structure and function.

Introduction: The vergence neural system was stimulated to dissect the afferent and efferent components of symmetrical vergence eye movement step responses. The hypothesis tested was whether the afferent regions of interest would differ from the efferent regions to serve as comparative data for future clinical patient population studies.
Methods: Thirty binocularly normal participants participated in an oculomotor symmetrical vergence step block task within a functional MRI experiment compared to a similar sensory task where the participants did not elicit vergence eye movements.
