Abstract

To investigate the brain activation in the prefrontal cortex (PFC) during mental works, we examined blood oxygenation changes of healthy subjects by using multi channel near infrared spectropcopy (NIRS). It was directly confirmed that the PFC was activated during mental tasks in vivo and it was suggested that distribution of the activation in the PFC is different among healthy individuals.
