Examination by near-infrared spectroscopy for evaluation of piano performance as a frontal lobe activation task.

The purpose of this study was to reveal the activation of the frontal lobe in piano performance by the use of near-infrared spectroscopy. Participants wereseven healthy volunteer music college students. The results of the examination showed a tendency towards an increase in total hemoglobin volume over a wider area in the frontal part of the brain during an appropriate piano task compared with an easy piano task or the Keio version of the Wisconsin Card Sorting Test.

[Examination of NIRS for evaluation of frontal lobe function in diffuse axonal injury (DAI) patients].

The purpose of this study is to compare diffuse axonal injury (DAI) patients with healthy controls by using near infrared spectroscopy (NIRS). The Wisconsin Card Sorting Test Keio Version (KWCST), a standard task paradigm to detect human frontal lobe dysfunction was set as a method. The result of the examination showed that compared with DAI patients, wider increase of total hemoglobin was admitted in the frontal part of the brain of healthy people during the KWCST.
