Gamma rhythm refers to the rhythmic electrical activity of the brain that happens at a frequency range of 30-100 Hz. This type of brain waves occur during a state of high concentration, deep meditation, and peak mental and physical performance. Synonyms for gamma rhythm include gamma wave, gamma oscillation, and gamma activity. Gamma waves are used in research to understand the mechanisms of sensory perception, attention, memory, and cognitive processing. Due to its association with cognitive and sensory processing, gamma rhythm is also linked to mental and neuropsychiatric disorders such as schizophrenia, dementia, and autism. Gamma oscillations play an essential role in brain function and cognition, and their study continues to be relevant to neuroscience research.
