Human gamma-band activity (GBA) has been related to a variety of functions ranging from perception and attention to memory and consciousness. Indeed fast spectral activity derived during numerous experimental paradigms has been interpreted as providing support for the functional importance of these signals. The present review provides an overview of findings demonstrating direct or indirect associations between GBA and behavioral measures of task performance or perceptual experience in humans. While the majority of papers have focused on perception and awareness, relationships between GBA and behavior have also been observed during insightful problem solving, short- or long-term memory, and motor tasks. In these studies, GBA was reported to predict behavioral measures such as correct response rates or reaction times both in healthy subjects and patients with neuropsychiatric disorders. The review demonstrates that there is increasingly strong evidence for a close association between GBA during both perceptual and cognitive tasks and behavioral outcome measures. With this in mind, the investigation of GBA might help elucidate the mechanisms underlying deficient functioning in patients with neuropsychiatric disorders.
人类γ波段活动（GBA）与多种功能有关，从感知和注意到记忆和意识。事实上，在许多实验范式中产生的快速频谱活动被解释为支持这些信号的功能重要性。本综述提供了一个概述，展示了 GBA 与人类任务绩效或感知体验的行为测量之间的直接或间接关联。虽然大多数论文都集中在感知和意识上，但在洞察力问题解决、短期或长期记忆以及运动任务期间也观察到了 GBA 与行为之间的关系。在这些研究中，据报道，GBA 可以预测健康受试者和神经精神障碍患者的行为测量指标，如正确反应率或反应时间。该综述表明，在感知和认知任务以及行为结果测量中，GBA 之间存在密切关联的证据越来越多。考虑到这一点，对 GBA 的研究可能有助于阐明神经精神障碍患者功能障碍的机制。
