Cerebellar cortex

What is the cerebellar cortex and how does it differ from the cerebral cortex. The value of the cerebellar cortex

The cerebellar cortex is located at the back of the brain. Sometimes it is given all the importance of the brain, which is somewhat incorrect. But this part of the central nervous system is very important. The fact is that, together with the thalamus of coordination functions, it is responsible for the motor centers in the brain and the entire musculoskeletal system. The leptophoric cerebellar cortex (the most anterior and largest) is the main element of this region. This part of the nerve cells receives signals coming from the basal ganglia: the substantia nigra, the caudate nucleus and the red nucleus. In other words, the cerebellar association cortex (mainly the superolateral and medial regions) receives information from other parts of the brain. It plays a big role in regulating the activity of internal organs - liver, kidneys, spleen, gastrointestinal tract. *Taking into account everything that was said above, we conclude that the cerebral cortex is closely connected with many parts of the body.*

Functions of the cerebellar cortex in humans and animals.

In humans, this cortex makes up 50% of the total area of ​​all functional areas of the brain. Since the cortex is always tuned only to movement, it controls not only local movements, but also regulates voluntary activity in general, controlling the postcentral and prefrontal cortex, pyramidal cells of the trunk. The cerebellar cortex is thus one of the most important parts of the brain as a whole. In addition, it is worth noting that the influence of the cortex on the spinal cord is also great. So the impulses coming from it stimulate the contraction of the corresponding muscles, which, in turn, contract, reporting this to the cortex through neuromotor activity. Such a message helps the brain understand not only where it wants to move, but also how best to do it. The cortex is also involved in the control of voice data. These impulses are formed in the motor radial cortex. From here we transmit messages to the Broca center. Here sounds are “processed” for pronunciation. And after that we move to the corticostriatal pyramid, which, in fact, is the motor center of speech. The cortex is also directly responsible for the motor activity of all internal organs. Its short pathways control breathing, vascular tone, heart function and many other body functions. Due to these functions, the cortex plays a huge role; even speech delay can be explained by disruption of connections between all these areas of the brain. Nerve impulses require nerve connections between certain structures. If something doesn't work somewhere, the signal being sent will be lost. This happens due to the incorrect functioning of the cortex. It disrupts the connection between the structures involved in the coordination of movements, language centers, motor centers of internal organs, which
