Analysis of cerebral blood flow changes during moving image viewing using near-infrared time-resolved spectroscopy

Analysis of cerebral blood flow changes during moving image viewing using near-infrared time-resolved spectroscopy

23

Seventeen healthy females and six healthy males were enrolled, and the median age was 21 (20-24 years old).

Twenty-four participants were registered, and twenty-two were completed. One was canceled due to a lack of communication, and one was excluded from the analysis because of missing the data due to interrupting a power failure during the measurement.

There was no occurrence of illness.

Primary outcome: There was no statistically significant difference in the ratio of oxygenated hemoglobin concentration during the fireworks/simple calculation (four arithmetic) task to the oxygenated hemoglobin concentration at rest (Wilcoxon singed-rant test). Secondary outcome: VAS values of the emotion scale by questionnaire showed significantly higher scores for enjoyment and like/dislike items in the fireworks task than in the calculation task (p<0.05 for each, t-test or non-parametric test for comparison between tasks).

In the subjective questionnaires survey, the fireworks task showed significantly higher values than the simple calculation task regarding Enjoyment and Like/dislike. While brain activity using TRS measurement did not show a significant difference between the fireworks and the simple calculation task.
