EEG asymmetry refers to differences in electrical activity recorded from the two hemispheres of the brain using electroencephalography (EEG). This asymmetry can manifest as differences in the amplitude or frequency of brain waves between the left and right hemispheres. Research in this area often focuses on understanding how these asymmetries are related to various cognitive and emotional processes, such as attention, emotion regulation, and language processing. EEG asymmetry has been studied in relation to conditions such as depression, anxiety, and other mental health disorders, as well as in healthy individuals to better understand normal brain functioning. The results of EEG asymmetry studies can provide valuable insights into brain function and potential biomarkers for assessing and diagnosing neurological and psychiatric conditions.
