The study characterizes EEG signatures associated with COVID-19 infection and recovery, comparing neurophysiological patterns between affected and control groups. Data collection included 8 minutes of eyes-closed resting EEG followed by alternating eye-state conditions, providing a comprehensive neurophysiological profile relevant to understanding post-COVID neurological sequelae.\",\n  \"methods_description\": \"EEG was acquired using a 10-20 standard montage.
