what are gamma waves used for

Gamma waves are a type of brainwave that have a frequency range of 30-100 Hz. They are the fastest brainwaves and are observed in the brain when it is actively engaged in cognitive processes, such as attention, learning, memory, and problem-solving. Gamma waves are associated with high levels of mental processing and are believed to be involved in complex thinking, perception, and conscious awareness. Researchers have also found that abnormalities in gamma wave activity may be associated with certain neurological and psychiatric conditions such as schizophrenia, Alzheimer's disease, and depression.
