What is nigra substantia?

Subania nigra is a area of ​​pigmented cells in the center of mobran, which is responsible for the production of neurotransmitter dopamine. This part of the brain plays an important role in controlling movement and it also seems to interact in the process of addiction. If you see the brain in the cross -section, the nigra substantia is located in the center of the brain, directly at the tip of the brain stem. You can also hear niggers referred to as the Niger Lokus. In addition to being considered part of midbrain, Nigra substantia is also part of basal ganglia, a complex network that controls movement, learning, emotions and several other important body functions.

Because nigra substantia is so critical for movement, it has a healthy nigra substantia. If a lesion appears in this area, people can experience movement disorders. For example, Parkinson's is associated with lesions and reduced activities in Nigra. Depending on how serious it is, patients may simply have problems with coordination, or may have serious tremor and other problems with movement.

Dopamin plays an important role in the motivational and rewarding cycle for the brain, which means it can play directly into addiction. When your brain learns that behavior will be rewarded, it will encourage you to participate in this behavior as often as possible, and dopamine receptors become more active whenever you participate in this behavior. Dopamine also contributes to mood and sleep regulation.

When nigra substantia is damaged, the patient may be offered supplementary dopamine to replace the lack of production. Since dopamine is not able to cross the Blood-Moza barrier, the predecessor of the dopamine is usually given, and the body converts the substance into dopamine over time.

This part of the brain is just one small aspect of a very large and complex organ, and it is quite possible that other Nigra substantia functions can be revealed over time because scientists learn more about the brain. Nigra's Nature also nefungs in a vacuum; It is affected by the health and activities of other areas of the brain that can disrupt or deregulate its function.
