The cerebellum is located at the back of the brain, immediately inferior to the occipital and temporal lobe s, and within the posterior cranial fossa. Each lobe of the brain has specific functions. The cerebellum receives nearly 200 million input fibres.Claude Ghez ,W. Thomas ThachTHE CEREBELLUM (Latin, little brain) constitutes only 10% of the total volume of the brain but contains more than half of all its neurons. The adult cerebellum anatomy consists of three parts, the vermis (median) and the two hemispheres (lateral), which are continuous with each other. After completion of this module, . Afferent information is delivered to the cerebellum as climbing fibers or mossy fibers. The basic cerebellar modules, A, B, C, and D, as defined by Voogd [ 7]havenow each been subdivided into several smaller entities and in some cases, based on similar peripheral receptive fields, these have been shown to comprise yet smaller units, termed microzones, which are the cortical component of micromodules [6 , 8-12]. Cerebellum works great in conjunction with React. The authors suggest that the computational function of the cerebellum is the same for all, and are performed by replicates of this one simple module.

Vestibulocerebellar output passes directly to brainstem. Both standard approaches and new advances are highlighted. Here is a picture from the cerebellum of a transgenic mouse expressing ChR2 (ChannelRhodopsin-2) and eYFP (Yellow Fluorescent Protein) in the basket cells of the cerebellum. The basic cerebellar modules, A, B, C, and D, as defined by Voogd [ 7] have now each been subdivided into several smaller entities and in some cases, based on similar peripheral receptive fields, these have been shown to comprise yet smaller units, termed microzones, which are the cortical component of micromodules [ 6, 8, 9, 10, 11, 12 ]. Two major feedforward control schemes have been proposed: the equilibrium-point control hypothesis6, 7, 8, 9and the inverse dynamics model hypothesis[4]. Indeed, a wealth of evidence from neuroanatomical, electrophysiological, neuroimaging and clinical studies has substantially modified our traditional view on the cerebellum as a sole calibrator of sensorimotor functions.

The cerebellum is known to play an important role in the coordination of movement. A new way to study cerebellar ataxia is the systematic analysis of the "reciprocal cerebellar circuitry" that consists of tightly organized reciprocal connections between Purkinje cells, dentate nuclei (DN), and inferior olivary nuclei (ION). Five major arteries connect directly to the circulatory system [5], making it the perfect location for systemic photobiomodulation. opmental mechanisms by which this order may emerge. These recent advances in cerebellar research point toward a model in which computation from the cerebellum could be required for spatial representation and would involve the integration of multi-source self-motion information to: (1) transform the reference frame of vestibular signals and (2) distinguish between self- and externally-generated . Module 1: Structure and Function of the Cerebellum . The cerebellum provides precise co- ordination of motor control for such body parts as the eyes, arms, fingers, legs, and wings. These afferent projections are somatotopically organized. The cerebellum controls your movement and learned sensorimotor skills; "it is an important sensorimotor structure" (Pinel & Barnes, 2018, p. 67). In this concept, a cerebellar module is defined as the conglomerate of one or multiple and non-adjacent, parasagittally arranged zones of Purkinje cells, their specific projection to a well-defined region of the cerebellar nuclei, and the climbing fiber input to these zones by a well-defined region of the inferior olivary complex.
