Gamma神经振荡的频率在30～100 Hz之间,存在于动物和人类大脑的多个区域,如丘脑、体感皮层以及海马等部位,在各个尺度水平上都可被检测到.抑制性中间神经元组成的神经网络是产生此高频节律性活动的主要条件之一.皮层的gamma神经振荡与丘脑-皮层系统有关.Gamma神经振荡具有易化突触可塑性和调节神经网络的作用,主要参与感觉特征绑定、选择性注意以及记忆等高级功能.
Gamma band oscillation ranges from 30 to 100 Hz. It can be recorded in many brain areas such as somotosensory cortex, hippocampus and thalamus. The gamma band oscillation can be detected at different levels such as microscopic (spikes), mesoscopic (local field potentials, LFP) and macroscopic (electroencephalogram, EEG) level. GABAergic inhibitory interneuron network is considered as the main source of the gamma oscillation generation, and the cortical gamma oscillation is also related with the interaction of thalamo-cortical system. Gamma band oscillation is associated with sensory and cognition functions, in particular the feature binding, selective attention and memory processing.
