Brain rhythms refer to the patterns of electrical activity that can be measured in the brain using tools such as electroencephalography (EEG) or magnetoencephalography (MEG). These rhythms are typically categorized based on their frequency, such as delta waves (0.5-4 Hz), theta waves (4-8 Hz), alpha waves (8-13 Hz), beta waves (13-30 Hz), and gamma waves (30-100 Hz). Research in brain rhythms focuses on understanding how these patterns of activity are generated, how they are related to different cognitive processes and behaviors, and how they may be disrupted in neurological and psychiatric disorders. This research area also explores the potential role of brain rhythms in communication between different brain regions and the integration of sensory information. Overall, studying brain rhythms provides valuable insights into the functioning of the brain and has applications in areas such as cognitive neuroscience, neuroimaging, and the development of new therapeutic interventions for brain disorders.
