Participants were asked to keep their eyes closed, and all lighting in the room was turned off during data collection. An intercom allowed communication between the experimental and the recording room.\nParticipants performed four blocks, 2 meditation blocks interspaced by two thining blocks (in which they are instructed to think actively). Half of the participants start with a meditation block, and half of them start with a thinking block. The first meditation block is a breath counting meditation for all participants. The second block is a tradition-specific meditation - except for the control group, for which it is a breath counting meditation.","recording_modality":["eeg"],"senior_author":"Claire Braboszcz","sessions":[],"size_bytes":58478045346,"source":"openneuro","study_design":null,"study_domain":null,"tasks":["med1breath","med2","think1","think2"],"timestamps":{"digested_at":"2026-04-22T12:25:55.218510+00:00","dataset_created_at":"2021-12-23T05:36:27.844Z","dataset_modified_at":"2021-12-10T18:20:38.000Z"},"total_files":392,"storage":{"backend":"s3","base":"s3://openneuro.org/ds003969","raw_key":"dataset_description.json","dep_keys":["CHANGES","README","participants.json","participants.tsv"]},"nemar_citation_count":7,"computed_title":"Meditation vs thinking task","nchans_counts":[{"val":79,"count":294},{"val":72,"count":98}],"sfreq_counts":[{"val":1024.0,"count":386},{"val":2048.0,"count":6}],"stats_computed_at":"2026-04-22T23:16:00.306682+00:00","tags":{"modality":"Auditory","pathology":"Healthy","type":"Attention"},"total_duration_s":239521.0,"author_year":"Delorme2021","canonical_name":null}}
