is that of the nerve cells of the substantia nigra (pars compacta) projecting to the striatum dopaminergic outgoing today because of a particularly strong modulation path explored within the basal ganglia is because people have realized that his disorder out due to a premature degeneration (aging) to the symptoms of Parkinson's disease.
The basal ganglia are a collection of nuclei that are located on either side of the thalamus, cingulate outside and above the limbic system, but below the gyrus and within the temporal lobe. Although here, as in the rest of the brain, glutamate is the most common neurotransmitters, the inhibitory neurotransmitter GABA plays the main role in the basal ganglia.
The largest group of these nuclei is called the corpus striatum ("striped body") called, consisting of the caudate nucleus (tail), putamen ("Shell") Globus pallidus ("pale globe") and Nucelus accumbens ("leaning"). All these structures are duplicated, one set on each side of the central septum.
The caudate nucleus is located just behind the frontal lobe and winds back toward the occipital lobe. He sent messages to the frontal lobes (particularly the orbital cortex, just above the eyes) and appears to be responsible to inform us that something is wrong and we should do something about it: Wash your hands! Close your doors off! As these examples suggest, is a hyperactive caudate nucleus is likely to obsessive-compulsive disorders [eng. Obsessive compulsive disorder (OCD)] involved. On the other hand, too little can actively be involved the caudate nucleus to various disorders, such as on the hyperactivity disorder [eng. ADD for Attention Deficit Disorder], depression, schizophrenia and aspects of simple lethargy. He is also involved in the PAP syndrome, a dramatic loss of motivation, as was discovered only recently (see below).
