Abstract
It is known that brain areas are defined by their functions independently, motor cortex and sensory cortex in particular are differently located in the adjacent area. To control the external device using brain-machine interface (BMI) techniques, we usually use the differences (ERD/ERS) of physiological response of motor cortex for inducing the motor imagery. On the other hands, to detect the tactile stimuli using BMI techniques, we employ the differences of the steady state evoked potentials of EEG in sensory cortex. Each BMI method can be separated by independent physiological responses. For discriminating the EEG response by hybrid protocols (tactile and no motor action, tactile and motor action, visual and motor action, visual + tactile and motor action) in the adjacent area, however, could be difficult, since EEG has a low spatial resolution property. In this study, the experiment employed the four protocols independently, obtained 64-channel EEG signals are quantitatively analyzed and demonstrated a difference of frequency responses in the motor cortex and sensory cortex.
