Cerebellum is a part of the brain which is situated at the nape area of the head. It is primarily involved in the regulation of motor response and activities. Aside from that, it also plays a significant role in cognition, attention span and speech or language. Also, it affects emotional functions. It regulates the reaction of fear and pleasure. Scientists state that cerebellum is not the part of the brain which initiates movement. However, it is significantly involved because it is responsible for the movement’s coordination, precision and timing.
Inside the brain, the cerebellum receives impulses from sensory organs and also from certain parts of the brain and spinal cord. It organizes these impulses into fine motor function. Cerebellum only involves the fine tune motor activity of the body. Therefore, if there will be damage to this part of the brain, it does not lead to paralysis but may cause incoordination on fine movement and affects balance, posture and motor abilities.
Anatomically, cerebellum seems to have a separate structure which is appended and inserted at the base of the cerebral hemispheres. It is coated with a structure that is grooved in parallel. This makes it different from the structure of the cerebrum which has irregular strokes of convolutions. Inside the cerebellum is a thin layer of neural tissue which is considered to be a continuation of the cerebral cortex. Among the most important neuron are the Purkinje cells and granule cells. This intricate complex of nervous tissues can produce an immense and substantial impulse – processing ability. However, almost every impulse output it generates, it is re – processed and regulated in a cerebellar nuclei which can be found inside the cerebellum.
Another function of cerebellum is that it is also required in the processing of many other kinds of motor learning ability most especially in adapting to the change of sensorimotor functions. Scientific studies of the brain have hypothesized that sensorimotor accuracy can be accounted to the synaptic plasticity that can be found inside the cerebellum.
As mentioned above, if the cerebellum is damaged, it will not cause paralysis. However, certain disorders especially on the individual’s motor activity may be developed if this part of the brain is damaged. The person may still be able to move and generate any kind of motor activity; however, it may be uncoordinated and out of timing. Precision and accuracy on a certain motor activity may also diminish. Like many other organ/system test in the body, there is also a standard examination for assessing the functioning of the cerebellum. In this test, the person will have to touch a target object at the length of an arm using his/her finger. A normal person without cerebellar damage can move and direct his/her fingertip in a fast, straight line towards the object. On the other hand, if the person has damage to the cerebellum, the person will have a hard time focusing in the target object and may reach the object very slow and erratic. This shows that motor function is still there despite the damage. The cerebellum is not responsible for initiating movements but to attune a comprehensive form of a certain movement.
Herbs that might help the brain and blood flow: Ginkgo Biloba, Vinpocetine, Huperzine A, DMAE, Gotu Kola, and Bacopa Leaf.
