Simultaneously collected EEG and BOLD signals for each participant were recorded and organized at each folder. EEG data were collected using a 32 channel MR-compatible EEG system (Brain Products, Munich, Germany). R128 in the EEG signals corresponds to the BOLD fMRI volume trigger.\n\nEach scanning section consisted of an anatomical session, two 10-min resting-state sessions, and several 15-min sleep sessions. The first resting-state session was conducted before a visual-motor adaptation task (Albouy et al, Journal of Sleep Research, 2013) and the second resting-state session was conducted after a visual-motor adaptation task. The scored sleep stages for these 33 subjects were organized under sourcedata folder. Each TSV file contained the sleep stages for each 30-sec epoch across different sessions for each subject.\n\nFor more information or any questions about this dataset, please see the manuscript on bioRxiv or contact Yameng Gu (ymgu95@gmail.com)\n\n\n\n","bids_version":"1.4.1","sessions_count":null,"publish_date":null,"embedding_dirty":0,"license_tier":"public","zarr_status":"ready","zarr_converted_at":"2026-08-04 17:05:08","zarr_store_count":253,"zarr_index_etag":"370f73c6fcfac851e107917b008c8cd1","zarr_source_commit":"630a85f1a80122c7d0dc713c6e5916818a2f537d","archive_status":"ready","archive_size":87854105797,"archive_retry_count":0,"records_status":"ready","archive_skip_reason":null,"zarr_errors":2,"zarr_failure_count":2,"zarr_deterministic":1,"zarr_failed_at":"2026-08-04 17:05:08","num_dataset_citations":16,"num_datapaper_citations":0,"n_channels":null,"electrode_system":null,"has_hed":0,"hed_version":null,"is_exemplar":0,"bytes_present":92839189492,"data_complete":1,"withdrawn_at":null,"withdrawn_reason":null,"archive_complete":null,"archive_absent_files":null,"archive_declared_files":null,"zarr_pool_breaks":null,"total_recording_duration":217552.1759999999,"recording_duration_min":525.204,"recording_duration_max":1113.92,"recording_count":255,"recordings_unavailable":2,"recordings_measured":253,"channel_count_min":32,"channel_count_max":32,"sampling_frequency":null,"power_line_frequency":null,"eeg_reference":null,"placement_scheme":null,"sweep_stamps":"{\"enrichment_updated_at\":\"2026-06-22 15:42:14\",\"metadata_updated_at\":\"2026-06-22 15:42:25\",\"archive_checked_at\":\"2026-06-22 16:38:43\",\"zarr_checked_at\":null,\"records_checked_at\":\"2026-06-22 16:09:13\",\"citations_updated_at\":\"2026-09-10 03:00:17\",\"channel_montage_checked_at\":\"2026-06-28 23:15:26\",\"hed_checked_at\":\"2026-06-30 04:47:31\",\"data_checked_at\":\"2026-08-03 03:00:18\",\"availability_report_at\":\"2026-07-23 01:15:10\",\"recording_stats_at\":\"2026-09-02 11:32:33\",\"signal_defaults_at\":\"2026-09-02 12:03:17\"}","participants":33,"num_citations":16,"latest_version":"v1.0.0","zarr_verify_status":null,"zarr_verified_at":null,"owner_username":"nemarAdmin","owner_github":"nemarAdmin","file_size_formatted":"86.46 GB","zarr_data_failures":{"count":2,"detail_ref":"zarr/index.json","compacted_by":"migration_0074"},"zarr_index_url":"https://zarr.nemar.org/on003768/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}}
