The change of brain blood flow was measured by functional near infrared spectroscopy (fNIRS) in subjects during practice of taichi-quan. Subjects were a veteran practitioner (male, 66 years old) and a beginner (male, 59 years old), and they were measured twice. The increase of blood flow was seen in the pre-frontal area in both subjects. Moreover, their patterns of electrodermal activity were similar.
