What is a striatum?

brain striatum, also called a strip core or a stretch body, is involved in a number of different cognitive processes. This part of the brain is called striatum , because its structural organization is such that it seems to be striped by layers of gray and white matter. The core of the stretch is part of the brain, which is also called the anterior brain due to its frontal position. Putamen; and a fundus that connects the core and putamen together. All these structures are also part of a basal ganglia system that plays a major role in learning, engine management and several other cognitive processes. A large number of sensory entry is accepted through a strip core and directed to other structures in the basal ganglia for processing.

There are several different types of neurons in the steep core. Most of this part of the bdéště consists of medium barbed neurons, which are important in controlling the body, limbs and movement of the eyes. Approximately 1% of the cells are spider cholinergic interneurons that reactThe neurotransmitter called acetylcholin, and it is assumed that it plays a role in determining behavioral reactions.

It is known that several different cognitive functions and processes are associated with brain pulp. The most well -defined role of this structure is to plan and perform motion paths. In addition, the core is important in the rewarding path. This term describes a complex network of brain processes that regulate motivation and create rewarding feelings and feelings. The way of reward provides a body or mind a reward, such as pleasant feelings or feelings, to perform behavior that promotes the survival of an individual or species.

The importance of the Central State is reflected not only in the types of functions associated with, but also in the types of diseases that affect this area of ​​the brain. Two of the most devastating progressive brain disorders, Parkinson's disease and Huntington's disease are associated with the dysfunction of the striatum. In each orADE disturbance of the core of the striking leads to disruption of the processes that this part of the brain is involved in regulation.

For example, one of the key aspects of Parkinson's disease is that certain types of neurons in the basal ganglial system no longer respond to a neurotransmitter called dopamine. Since this part of the brain is important in controlling and performing movement, Parkinson's disease is characterized by tremor, muscle rigidity and other forms of dysfunctional movement. In Huntington's disease, a mutant form of protein called huntingtin accumulates in the core of the stretch, prevents normal function and leads to the movement and behavior of the disorder.
