Pattern of neural oscillation in humans with a frequency between 25 and 140 Hz
Not to be confused with gamma rays.
A gamma wave or gamma rhythm is a pattern of neural oscillation in humans with a frequency between 25 and 140 Hz, the 40 Hz point being of particular interest.[1] Gamma rhythms are correlated with large-scale brain network activity and cognitive phenomena such as working memory, attention, and perceptual grouping, and can be increased in amplitude via meditation[2] or neurostimulation.[1][3] Altered gamma activity has been observed in many mood and cognitive disorders such as Alzheimer's disease,[4] epilepsy,[5] and schizophrenia.[6]
