Analysis on the Frontal Cortex in Cognitive Tasks for Brain-Computer Interface

摘要：

The frontal cortex is the part of the brain that relates to higher brain functions,such as planning,logical thinking,and emotion.As part of the development of a brain-computer interface,we tested whether the frontal cortex reacts differently in people as they performed different cognitive tasks.The reaction of the cortex was tested using electroencephalogram (EEG) and near-infrared spectroscopy (NIRS).Our preliminary research results showed a difference in blood flow volume occurred before and after some of assigned tasks;however,in EEG potentials,therewas no particular difference.We believe cognitive processes might be the cause of the difference in frontal cortex activity.
