What is pars reticulata?

Pars Reticulata is one of the two sections in the structure of the midbrain called the nigra substantia. This structure is one of the four cores that form a system of basal ganglia, a brain structure responsible for functions such as a selection of actions and efforts to reward. Nigra par

The second part of Nigra is the PARS Compacta, which takes access from other areas of basal ganglia and sends information back. On the contrary, pars reticulata also receives input, but sends signals for basic ganglia and can control the head and eyes. Compacta Pars is a more well -known aspect of nigra substantia because of its connection with the production of dopamine, epilepsy, chorea and Parkinson's disease, and some scientists believe that this part of the brain can also be involved in schizophrenia.

Pars Reticulata dysfunction deteriorates Parkinson's disease and contributes to the sporadic movement of the head and eyes, which is a symptom of the condition. It can also contribute to such spastic movements characteristic of epileptics because normally functioning pars reticulataIt plays a role in moderating seizures. The structure is primarily composed of spontaneous shooting of neurotransmitters of gamma acid (GABA), which are associated with inhibition of movement. This is what allows a person to sit in peace or point on the screen without touching it. The ability to manipulate the detonation of these neurotransmitters in epileptics can lead to a method of suppression of seizures.

Anatomically, neurons pars reticulata occupy a larger area than in the pars compacta, making it a larger part of the nigra substantia. Neurons Pars Compacta have structures similar to a tree called dendrites, which form a connection with pars reticulata, indicating that both areas have a certain effect on dopamine production. Pars Reticulata has a larger connection with the brain areas that have a strong inhibitory control over physical movements than any other part of the basal ganglia. It is also assumed that it is also associated with parts of the brain that apply control over aspects of behavior.

production of neurotransmitters GABA, or Gabaergic Neurons, is an important function of Pars Reticulata, which is shared with pars lateralis. Gaba suppresses hyperactive neural activity in the nervous system and directly contributes to the regulation of muscle tone in humans. It is a GABA production that allows Pars Reticulata to help control engine control by providing movement inhibition.
