Abstract

The role of alpha oscillations (8-13 Hz) in cognition is intensively investigated. While intracranial animal recordings demonstrate that alpha oscillations are associated with decreased neuronal excitability, it is been questioned whether alpha oscillations are under direct control from frontoparietal areas to suppress visual distractors. We here point to a revised mechanism in which alpha oscillations are controlled by an indirect mechanism governed by the load of goal-relevant information - a view compatible with perceptual load theory. We will outline how this framework can be further tested and discuss the consequences for network dynamics and resource allocation in the working brain.

摘要

α波振荡（8-13赫兹）在认知中的作用已得到深入研究。虽然颅内动物记录表明α波振荡与神经元兴奋性降低有关，但α波振荡是否受额顶叶区域直接控制以抑制视觉干扰物仍存在疑问。我们在此指出一种修正机制，即α波振荡由与目标相关信息的负荷所支配的间接机制控制——这一观点与知觉负荷理论相符。我们将概述该框架如何能得到进一步验证，并讨论其对工作大脑中网络动力学和资源分配的影响。
