What is premotor bark?
In the human brain, the premotor cortex consists of interconnected areas in the primary motor cortex, located in the frontal lobe of the brain. The word "motor" refers to the function of areas to send messages to move body movements to perform specific tasks. Premotor bark has a side and media area. Each of the two areas is connected by nerve paths that act as a number of electrical wires, with a primary motor bark. The side area controls physical movement in response to the external stimulus, while the media area responds to the inner stimulus from the brain itself and transmits the intention to perform a specific physical act.
neurons are the basic structural units of the nervous system. Most neurons in the lateral region are assumed that it is associated with the occurrence of motor functions such as the gripping of the building. Research involving monkeys has generally supported this conclusion. When the monkeys were trained on the river in different directions after a visual allusion, neurons in the side area began to "shoot" or transmit information, rmore in the time between the allusion and the physical act of achieving. This suggests that physical movement was in response to the outer stimulus.
The medial area of the premotor cortex is also involved in body movement and motor skills. However, it is assumed that this area works on the inner instead of an external stimulus. Scientists point to the fact that monkeys with removed media areas show a significant reduction in the amount of physical movements initiated by the monkeys themselves. At the same time, physical movement in response to external allusions remained the same. This suggests that the stored information in the media area relys on their own coding for performing specific movements.
imaging studies suggest that the media area of the fuu people of people in almost the same way. The media area is activated when test entities perform motor tasks from memory. This also applies to the absence of any visual stimuli or written or spellsthe instructions.
Human brain studies also support the connection between motor bark and physical movement. Patients with frontal lobe damage have difficulty learning to choose a specified movement based on visual allusions. This difficulty occurs even if the patient understands the instructions and eventually performs the right movement. Individuals with premotor cortex lesions can also demonstrate difficulties in monitoring visual or verbal commands to perform externally movement.
