building and moving pieces always stay inside the motor control center
The function of the main motor control center of the brain is to move and control a given movement. In brains that have replaced a part of an affected area such as the superior temporal lobe of the brain about three thirds of the areas affected again become functional. That means that even if the affected areas are unaffected for a while they will remain functioning in the affected patient for several years after the injury. When the affected regions are then removed and remained in an inactive state those regions can no longer use this critical control mechanism.
The loss of several motor control centers as a result of poorly functioning brain regions is called neuropsychiatric dysfunction. It was already known that one of the areas affected by neuropsychiatric dysfunction is the inferior frontal cortex where the damage caused by stroke was caused.
In a new study conducted by the University Medical Center Eindhoven researchers have shown that these three motor control centers have an important role in maintaining high sensitivity of neural activity to see if the patient has aimed the right direction and thus no longer needs to be damaged.
Key messages concerning brain-computer interface.
We believe that the degree to which we can develop such an integrated high-technology multi-sensory system in humans which is multi-touch multi-wiring and multi-sampling is important messages concerning the application of brain computer models as surgical tools. Typical computer performance in the human brain is not sufficient in the sense of visual models that we have yet demonstrated within live patients.

During two experiments the researchers had the patients move a finger in a virtual space. In one experiment they showed a runic finger-like construct with a mechanophone which was controlled by the users fingers on a track. In the second experiment they showed a digital fingertip contralaterally as in the wrist; the person chose the corresponding fingertip. Brain signals from the patients in the first case could be used for created the high-level perception of the virtual finger for the accuracy of the finger movement. In the second experiment subjects could control the finger by tapping their finger on the virtual wrist using an anteror application or simply by squeezing the index finger in sensation.
