▲ [17p-P1-5] Attentional effects in real life settings upon tea consumption as measured by wearable (HOT-1000) functional near infrared spectroscopy device
キーワード：brain funcitonal imaging, Absorption, Scattering
Recently, both black and green ta are getting attention because of their positive health effects. The main origin for these effects stems from two compounds found in the tea, caffine and L-theanine. Caffine is related to attention, energy, motivation, self-confidence, alertness and concentration. On the other hand, theanine is related to relaxation. Therefore drinking tea is supposed to make one alert at the same time give some relaxation too. Up to now there have been a few reports that use functional MRI or EEG to investigate the neural activity1,2. We propose the use of using wearable devices in monitoring neural activity through optical signals and focuses on addressing changes in attention with consumption of green, lemon and milk teas.
