Gamma waves are a type of brain wave that have a frequency between 30 and 100 Hz. They are the fastest brain waves and are associated with high-level cognitive functions, such as problem-solving, memory processing, and information retention. Gamma waves are often linked to states of heightened perception and consciousness. Research suggests that gamma waves may play a role in the brain's ability to integrate information from different sources. They are also observed during moments of intense focus or meditation, indicating their importance in mental clarity and awareness. Understanding gamma waves can help in studying various cognitive processes and neurological conditions.
