ばく露装置の詳細 The mobile phone was mounted on the left side of the subject's head in normal position for use. The antenna was located about 4 cm apart from the head, over the posterior areas of the left temporal lobe. The RF power was switched on and off via a data cable from a laptop.
Additional information Each subject was tested twice within a single session, with and without RF exposure.

研究の主なアウトカム(著者による)

The radiofrequency field speeded up response times when three items had to be kept in memory but no effects of radiofrequency were revealed with lower loads. The data suggest that radiofrequency fields have a measurable effect on human brain function and cognition.
