This review describes a wide range of functional correlates of gamma oscillations in whole-brain work, in neuroethology, sensory-cognitive dynamics, emotion, and cognitive impairment. This survey opens a new window towards understanding the brain's gamma activity. Gamma responses are selectively distributed in the whole brain, and do not reflect only a unique, specific function of the nervous system. Sensory responses from cortex, thalamus, hippocampus, and reticular formations in animal and human brains, and also cognitive responses, were described by several authors. According to reviewed results, it becomes obvious that cognitive disorders, and medication-which influence the transmitter release-change entirely the understanding of the big picture in cognitive processes. Gamma activity is evoked or induced by different sensory stimuli or cognitive tasks. Thus, it is argued that gamma-band synchronization is an elementary and fundamental process in whole-brain operation. In conclusion, reasoning and suggestions for understanding gamma activity are highlighted.
这篇综述描述了伽马振荡在全脑工作中的广泛功能相关性，包括神经生态学、感觉认知动力学、情绪和认知障碍。这项研究为理解大脑的伽马活动开辟了新的视角。伽马反应在整个大脑中选择性地分布，不仅反映了神经系统的独特特定功能。几位作者描述了来自动物和人类大脑皮层、丘脑、海马体和网状结构的感觉反应，以及认知反应。根据综述结果，很明显，认知障碍和影响递质释放的药物——完全改变了对认知过程全貌的理解。伽马活动是由不同的感觉刺激或认知任务引起或诱发的。因此，有人认为，伽马频带同步是全脑运作的基本和基本过程。总之，本文强调了对伽马活动的推理和理解建议。
