研究了人体对不同周期闪烁光的主观偏好对应的大脑皮层反应。进行配对比较测试，以检查对闪烁灯光的主观偏好，并在交替呈现最喜欢和不喜欢的闪烁灯光时记录脑磁图。结果表明，在优选条件下，代表脑磁α波重复性特征的自相关函数的有效持续时间变长。这表明，大脑在偏好的条件下会重复类似的节奏。
Human cortical responses corresponding to the subjective preference for a flickering light of varying period were investigated. Paired-comparison tests were performed to examine the subjective preference for a flickering light, and MEG was recorded during presentations of the most preferred and less preferred flickering lights alternately. Results showed that the effective duration of the autocorrelation function, &tgr;e, which represents a repetitive feature of the MEG alpha waves, becomes longer during the preferred condition. This reveals that the brain repeats a similar rhythm under preferred conditions.
