Recent physiological studies have implicated theta - a high-amplitude 4-8 Hz oscillation that is prominent in rat hippocampus during locomotion, orienting and other voluntary behaviors - in synaptic plasticity, information coding and the function of working memory. Intracranial recordings from human cortex have revealed evidence of high-amplitude theta oscillations throughout the brain, including the neocortex. Although its specific role is largely unknown, the observation of human theta has begun to reveal an intriguing connection between brain oscillations and cognitive processes.
最近的生理学研究表明,θ波(一种高振幅的4-8赫兹振荡,在大鼠运动、定向及其他自主行为过程中,海马体中尤为显著)与突触可塑性、信息编码及工作记忆功能有关。对人类大脑皮层的颅内记录显示,包括新皮层在内的整个大脑都存在高振幅θ振荡的证据。尽管其具体作用在很大程度上尚不清楚,但对人类θ波的观察已开始揭示大脑振荡与认知过程之间的一种有趣联系。
