what is the function of the cerebellum?

It plays an important role in the integration of sensory perception and motor output. Fine tunes the body position and motor movements.

Here's the lot for you, more than what you asked for-\n\nAmygdala – limbic structure involved in many brain functions, including emotion, learning and memory. It is part of a system that processes "reflexive" emotions like fear and anxiety.\n\nCerebellum – governs movement.\n\nCingulate gyrus – plays a role in processing conscious emotional experience.\n\nFornix – an arch-like structure that connects the hippocampus to other parts of the limbic system.\n\nFrontal lobe – helps control skilled muscle movements, mood, planning for the future, setting goals and judging priorities.\n\nHippocampus – plays a significant role in the formation of long-term memories. \n\nMedulla oblongata – contains centers for the control of vital processes such as heart rate, respiration, blood pressure, and swallowing.\n\nLimbic system – a group of interconnected structures that mediate emotions, learning and memory.\n\nOccipital lobe – helps process visual information.\n\nParahippocampal gyrus – an important connecting pathway of the limbic system.\n\nParietal lobe – receives and processes information about temperature, taste, touch, and movement coming from the rest of the body. Reading and arithmetic are also processed in this region.\n\nPons – contains centers for the control of vital processes, including respiration and cardiovascular functions. It also is involved in the coordination of eye movements and balance.\n\nTemporal lobe – processes hearing, memory and language functions. \n\nThalamus – a major relay station between the senses and the cortex (the outer layer of the brain consisting of the parietal, occipital, frontal and temporal lobes).

I looked this one up in my neuroscience book. Thought I'd add to the above answer. \n\nIt looks like it is hierarchical because of the motor subsystems. Two of these subsystems are Lower and upper motor neurons. Upper are located in the brainstem or cerebral cortex while lower send axons out of the brainstem and spinal cord. Third and forth subsystems regulation teh upper motor systems. Third, cerebellum, forth basal ganglia. \n\nThe interactions are more detailed and too much to type. Good luck. \n\nBTW: I like these sorts of questions.

Your "thought" of movement starts in the precentral gyrus, the signal travels to the cerebellum via pontine nuclei, then the action potential is sent, but it is sloppy movement and still needs calibration.  This is done after afferent signals from the proprioceptive neurons combine with the first set of efferents and the 2 are compared.  The signals then are refined by the precentral gyrus and secondary impusles for the same movement are again sent down the pathway.

It has its basis in brain structure.  I saw it on Discovery Channel a while back.

Function\nThe superior temporal gyrus includes an area (within the Sylvian fissure) where auditory signals from the cochlea (relayed via several subcortical nuclei) first reach the cerebral cortex. This part of the cortex (primary auditory cortex) is involved in hearing. Adjacent areas in the superior, posterior and lateral parts of the temporal lobes are involved in high-level auditory processing. In humans this includes speech, for which the left temporal lobe in particular seems to be specialized. Wernicke's area which spans the region between temporal and parietal lobes plays a key role (in tandem with Broca's area, which is in the frontal lobe). The functions of the left temporal lobe are not limited to low-level perception but extend to comprehension, naming, verbal memory and other language functions.\n\nThe underside (ventral) part of the temporal cortices appear to be involved in high-level visual processing of complex stimuli such as faces (fusiform gyrus) and scenes (parahippocampal gyrus). Anterior parts of this ventral stream for visual processing are involved in object perception and recognition.\n\nThe medial temporal lobes (near the sagittal plane that divides left and right cerebral hemispheres) are thought to be involved in episodic/declarative memory. Deep inside the medial temporal lobes, the hippocampi seem to be particularly important for memory function, and they also seem to play a part in controlling spatial behavior

The Cerebellum is the "CPU". It processes all the information. It is also the "USB port" because it is linked to the spine, or "USB cord". The lobes are the "Hard drives, CMOS" The sides are the keyoard and mouse, because they are the input devices.

During muscle contraction the strands of collagen are stretched as the muscle shortens. This stretching deforms the terminals of the Ib afferent axon, opening stretch-sensitive cation channels. As a result, the axon is depolarized and fires nerve impulses up to the central nervous system via the spinal cord. The action potential frequency signals the force being developed within the muscle.\n\nThis sensory feedback plays an important role in spinal reflexes and in the central control of muscle contraction. Specifically, it is postulated that because a Golgi tendon organ exists in serial connection with muscle fibers, it can measure the tension that each muscle contraction builds up. The Ib afferent axon synapses with interneurons within the spinal cord and also relays information to the brain. One of the main spinal reflexes receiving an input from the Ib afferent is the autogenic inhibition reflex, which is involved with the regulation of the force profile of on-going muscle contractions.\n\nThe ascending pathways to the cerebellum are the dorsal and ventral spinocerebellar tracts and are involved in the cerebellar regulation of movement.

ok  this is  something the bird  learns  so its a  skill \nmotor  skills  are saved  evolved and  controled  by the assosiation of many parts of the barin but meaily it is  saved in the motor association area (is posterior to the post central gyri in the pareital lobe of the  brain under the postcentral sulcus) and controled by werniks area( in the superfitial pareital lobe anterior and inferior  to the triangular area of the transvers  sulcus)\nthese areas  are much more devaloped in the human beeing but they r  also present in the birds brain and  they controle  these muscle movements\nalso some corticospinal corticobulbar and  corticorubral tracts have some influence on that \nmaybe som other  areas  as the pyramidal area the substantia nigra the olive nucleus of medulla oblongata and the subcallousal area can have some  infuence as they are all  interconnected

what they did with that mouse.. was..\n\nthey were able to recognize what areas of the brain that control movements of the limbs, they had a plate of sensors inserted into a man's skull and he was able to manouver a pointer in the computer with pure thought\n\nit works only by sensing electrical impulses in specific areas of the brain. and it could one day lead to conecting fake limbs to handicapped people

No - the brain is an organ. However, you can "exercise" it by learning new things and solving problems.  Keeping your brain active helps to stimulate new brain cells and possibly fight dementia in later years.

Cerebrospinal fluid occupies both the ventricular system (http://en.wikipedia.org/wiki/Ventricular_system) of the brain and the spinal cord(http://en.wikipedia.org/wiki/Spinal_cord). It has many roles such as shock absorption, nutrition, waste disposal and communication (see reference 1).

Medulla oblongata. [L., oblong medulla] (Anat.), the posterior part of the brain connected with the spinal cord. It includes all the hindbrain except the cerebellum and pons, and from it a large part of the cranial nerves arise. It controls very largely respiration, circulation, swallowing, and other functions, and is the most vital part of the brain; -- called also bulb of the spinal cord. See Brain.

Also known as ACh, it functions to activate an action potential, and since you are referring to psyh., ACh would help the brain interpret b/w the 2 hemispheres(right/left), which as you know, depending on which side the brain is activated, will determine your analytical, thinking and emotional repsonses.
