What are dopaminergic neurons?
dopaminergic neurons are primarily found in the nigra par compacts some dopaminergic neurons are located in the hypothalamus in the arc nucleus. These neurons use a neurotransmitter dopamine to transmit messages to the body. Dopamine controls many functions of the brain, including mood, stress and muscle control. The absence of dopaminergic neurons can cause the development of Parkinson's disease. These are the mesocortical path, the mesolimbic road, the nigrostriatal path and the tuberoinfundibular path. Some dopaminergic neurons can travel between roads.
Dopaminergic neurons are the main source of dopamine production in the body. Low dopamine levels can be responsible for depression, some sleep disorders, and the inability to focus on the task. High levels of dopamine make measuring compulsive behavior and plays a role in the feeling of reward dependence. Dopaminergic neurons can excite before a pleasant activity, causing the urge to engage in the activity. The first symptom he noticed may be manual tremor,that affects only one side of the body. As the disease progresses, most symptoms can affect one side of the body more than on the other side of the body.
slow movements or stiff muscles may occur between many with Parkinson's disease due to lack of dopamine available for brain use. Some people may not be able to flash or gesture when they talk to this disease after a long time. In the end, many people find that their ability to speak has changed, and can mut the monotonous or repeat of the word before completing the sentence.
Treatment of Parkinson's disease usually focuses on replacing dopamine in the brain. Dopaminergic neurons need a prepared neurotransmitter supply to avoid involuntary movements that are a characteristic feature of Parkinson's disease. The brain cannot use some forms of synthetic dopamine and most doctors believe that the most effective drug available isL-dopamine.
A dopamine agonist can be used to deceive the brain into functioning as if dopamine was present in the brain. Dopaminergic neurons use dopamine agonists to control involuntary movements and for mood regulation. These drugs can cause unusual behavior in those who take them, and some people can eat, gamble or engage in promiscuous sexual activity. Some people with Parkinson's disease may require brain surgery to treat the condition if dopamine replacement has failed.
