Study 1: 80 healthy participants (2 removed) + 5 placebo session from a pilot of the drug study.  Total n=83.  Study 2: 30 healthy participants (3 dropout) in a double-blind drug study.    Total n=27.   Drug was Cabergoline 1.25 mg.   Study 1 subjects had IDs 101-180 and the 5 placebo were 301/401 - 305/405.   Study 2 subjects had IDs 305/405 - 330/430.   The dual numbers were for session:  300s were first session, 400s were second session.  Here we have simply put them in as session 1 and session 2.   So Joe Smith would have been 305 on visit 1, then 405 on visit 2.  If he got cab first we indicated that in the Sess1_Drug column.   EEG published here: 10.1038/ncomms6394.   Task included in Matlab programming language.   Data collected circa 2012-2013 in Laboratory for Neural Computation & Cognition at Brown.  Check the .xls sheet under code folder for more meta data.   Triggers are complicated.  See CC_Triggers.mat under code folder.  A few old analysis scripts are included.  - James F Cavanagh 02/15/2021","bids_version":"1.1.1","sessions_count":2,"publish_date":null,"embedding_dirty":0,"license_tier":"public","zarr_status":"ready","zarr_converted_at":"2026-09-06 20:23:57","zarr_store_count":137,"zarr_index_etag":"94d6b31772bdb4fd3647f13b22f4ea00","zarr_source_commit":"b4a67d3b272c1bcd6f0fbb4ec31fe67a44d6ad68","archive_status":"ready","archive_size":37569161687,"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":76,"n_channels":64,"electrode_system":"10-10","has_hed":0,"hed_version":null,"is_exemplar":0,"bytes_present":42406585164,"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":323595.66799999995,"recording_duration_min":1850.264,"recording_duration_max":2806.68,"recording_count":137,"recordings_unavailable":0,"recordings_measured":137,"channel_count_min":64,"channel_count_max":64,"sampling_frequency":500,"power_line_frequency":60,"eeg_reference":"CPz","placement_scheme":null,"sweep_stamps":"{\"enrichment_updated_at\":\"2026-06-22 02:39:18\",\"metadata_updated_at\":\"2026-06-22 02:39:18\",\"archive_checked_at\":\"2026-06-22 03:05:43\",\"zarr_checked_at\":null,\"records_checked_at\":\"2026-06-22 02:40:32\",\"citations_updated_at\":\"2026-09-08 03:00:47\",\"channel_montage_checked_at\":\"2026-06-28 23:12:13\",\"hed_checked_at\":\"2026-06-30 04:43:45\",\"data_checked_at\":\"2026-08-01 03:01:00\",\"availability_report_at\":\"2026-07-23 01:14:12\",\"signal_defaults_at\":\"2026-09-02 12:00:08\",\"recording_stats_at\":\"2026-09-07 03:01:05\"}","participants":110,"num_citations":76,"latest_version":"v1.0.0","zarr_verify_status":null,"zarr_verified_at":null,"owner_username":"nemarAdmin","owner_github":"nemarAdmin","file_size_formatted":"39.51 GB","zarr_data_failures":null,"zarr_index_url":"https://zarr.nemar.org/on003518/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}}
