We have studied the effects of various disturbances of two different levels of difficulty, that is, with weak and with strong difficulty levels for primary visual and motor tasks. In the case of visual task with motor and mental disturbances, we found it decreased as motor and mental disturbance difficulty-level increased, ***compared with the cases without motor and mental disturbances. To the contrary, in the case of motor activity, the total activation of motor cortex with weak and with strong mental disturbance was increased as mental disturbance difficulty-levels increased.
