1研究背景人们对高级认知任务下γ震荡的活性非常感兴趣。γ震荡的产生与调节是由于抑制了以GABA作为神经递质的中间神经网络。最近的研究显示,γ震荡是参与工作记忆的主要神经生理学机制,γ频率范围内的神经元震荡与认知相关。在较高的认知需求下,工作记忆可以使γ震荡增强,特别是在背外侧前 1 Research Background People are very interested in the activity of γ-oscillations in advanced cognitive tasks. The generation and regulation of γ oscillations is due to the inhibition of an intermediate neural network that uses GABA as a neurotransmitter. Recent studies have shown that γ oscillations are the primary neuropsychological mechanisms involved in working memory and that neuron oscillations in the γ-frequency range are associated with cognition. With higher cognitive needs, working memory can make gamma oscillations stronger, especially in the dorsolateral front
