Attention: Gamma waves have been documented to help with attention – specifically attentive-focus. Specifically when the brain increases the 40 Hz frequency, various parts of the brain are able to function with efficiency and unison.
Binding of senses: They bind all the senses together in the brain. In other words, they help your brain process smells, sights, and sounds simultaneously.
Focus: Individuals with high level mental processing and functioning tend to exhibit greater gamma activity throughout the brain.
Compassion: In a study with Buddhist monks, it was found that gamma activity increased when they entered a meditative state of compassion.
Consciousness: The gamma waves throughout your brain help you understand your environment and dictate your experience of consciousness.
Meditation: Advanced monks have been documented as having increased amounts of gamma activity. This is a result of their meditative practices.
Mental Processing: Your overall mental processing is influenced by your gamma brain waves.
Perception: How you perceive reality and how aware you are is directly tied to 40 Hz gamma activity.
R.E.M. Sleep: Gamma brain waves play an important role in the R.E.M. or Rapid-Eye Movement sleep stage.
Subjective awareness: Some have suggested that gamma wave activity correlates with subjectivity. However, this is a claim that is not scientifically supported.
Unity of consciousness: One popular theory suggests that these brain waves contribute to “unity of consciousness.” This is just a theory – take it with a grain of salt.
