α波段振荡是人脑中的主要振荡,最近的证据表明它们具有抑制功能。尽管如此,毫无疑问,α波段振荡在信息处理中也起着积极的作用。在本文中,我建议α波段振荡具有两个角色(抑制和时机),它们与两个基本注意力(抑制和选择)紧密相关,可以使受控的知识访问和语义取向(能够有意识地面向方向取向)在时间,空间和上下文中)。因此,α波段的振荡反映了最基本的认知过程之一,也可以证明在不同频率的大脑活动的合并中起关键作用。
Alpha-band oscillations are the dominant oscillations in the human brain and recent evidence suggests that they have an inhibitory function. Nonetheless, there is little doubt that alpha-band oscillations also play an active role in information processing. In this article, I suggest that alpha-band oscillations have two roles (inhibition and timing) that are closely linked to two fundamental functions of attention (suppression and selection), which enable controlled knowledge access and semantic orientation (the ability to be consciously oriented in time, space, and context). As such, alpha-band oscillations reflect one of the most basic cognitive processes and can also be shown to play a key role in the coalescence of brain activity in different frequencies.
