Researchers identified the energy intensity corresponding to an average rating of 7 from the participants. Subsequently, each participant underwent 30 laser stimulis and provided verbal pain ratings one by one. The pain ratings were on a scale where 0 indicated no sensation at all, 4 indicated the onset of pain, 6 represented moderate pain, 8 indicated severe pain, and 10 denoted unbearable pain.\n2.Participant task information(description of the experiment): \nParticipants underwent laser stimulation and subsequently verbally rated the intensity of pain.\n3.Participant instructions(as exact as possible):\nParticipants were instructed to focus on the laser stimulation, keep their eyes open, and fix their gaze on the crosshairs displayed on the screen. After each laser stimulation, there is a five-second pause. Participants then rated the intensity of the pain. Subsequent trials began at random 5 seconds after the score was provided.\n4.References and links:\nNone\n5.Comment:\nAll laser markers are delayed by 100ms","bids_version":"1.1.1","sessions_count":null,"publish_date":null,"embedding_dirty":0,"license_tier":"public","zarr_status":"ready","zarr_converted_at":"2026-09-06 04:48:46","zarr_store_count":30,"zarr_index_etag":"0b15d26807fddbf73b837eee167edd8f","zarr_source_commit":"fd7194026dfd2373b7e93f8f5ad3d00adebda63d","archive_status":"ready","archive_size":17041014162,"archive_retry_count":0,"records_status":"ready","archive_skip_reason":null,"zarr_errors":0,"zarr_failure_count":0,"zarr_deterministic":0,"zarr_failed_at":null,"num_dataset_citations":0,"num_datapaper_citations":0,"n_channels":32,"electrode_system":"10-10","has_hed":0,"hed_version":null,"is_exemplar":0,"bytes_present":20784775786,"data_complete":1,"withdrawn_at":null,"withdrawn_reason":null,"archive_complete":null,"archive_absent_files":null,"archive_declared_files":null,"zarr_pool_breaks":0,"total_recording_duration":76167.88399999998,"recording_duration_min":2365.416,"recording_duration_max":3046.088,"recording_count":30,"recordings_unavailable":0,"recordings_measured":30,"channel_count_min":32,"channel_count_max":56,"sampling_frequency":1000,"power_line_frequency":50,"eeg_reference":"CPz","placement_scheme":null,"sweep_stamps":"{\"enrichment_updated_at\":\"2026-06-18 10:20:22\",\"metadata_updated_at\":\"2026-06-18 10:20:26\",\"archive_checked_at\":\"2026-06-18 10:33:52\",\"zarr_checked_at\":null,\"records_checked_at\":\"2026-06-18 10:21:52\",\"citations_updated_at\":null,\"channel_montage_checked_at\":\"2026-06-28 23:40:13\",\"hed_checked_at\":\"2026-06-30 05:14:17\",\"data_checked_at\":\"2026-07-23 03:00:07\",\"availability_report_at\":\"2026-07-23 01:23:35\",\"signal_defaults_at\":\"2026-09-02 12:27:01\",\"recording_stats_at\":\"2026-09-07 03:01:09\"}","participants":30,"num_citations":0,"latest_version":"v1.0.0","zarr_verify_status":null,"zarr_verified_at":null,"owner_username":"nemarAdmin","owner_github":"nemarAdmin","file_size_formatted":"19.36 GB","zarr_data_failures":null,"zarr_index_url":"https://zarr.nemar.org/on005286/zarr/index.json","attestation_deposit_type":null,"attestation_key_status":null,"attestation_deidentified":null,"attestation_no_duplicate":null,"attestation_upstream_source":null,"attestation_accepted_at":null}}
