A study of Preksha meditation using electroencephalography (EEG) found that different forms of the meditation could not be clearly distinguished by brain activity. Thirteen novice meditators (10 females, 3 males; ages 19-49) had EEG data collected before and after an eight-week intervention (three sessions per week). A support vector machine algorithm classified brain activity among meditation forms with only 6-12% accuracy, indicating no clear EEG changes. The format of Preksha meditation studied did not elicit discernable brain activity differences using this method.
