Participants performed four different motor imagery conditions (reach, twist, lift, grasp) across three sessions with 40 trials each, following a standardized paradigm with visual cueing and fixation periods. The multimodal biosignal acquisition provides complementary hemodynamic and electrophysiological measures of motor imagery processing in a clinical population.\",\n  \"methods_description\": \"EEG and fNIRS data were acquired simultaneously during motor imagery tasks. Each trial consisted of a 3-second fixation cross, followed by a 4-second visual cue indicating the motor imagery task, a 3-second ready state with gray screen, and a 5-second motor imagery execution period. Four motor imagery conditions (reach, twist, lift, grasp) were presented in random order across 40 trials per session.\",\n  \"keywords\": [\n    {\n      \"term\": \"EEG\"\n    },\n    {\n      \"term\": \"fNIRS\"\n    },\n    {\n      \"term\": \"motor imagery\"\n    },\n    {\n      \"term\": \"brain-computer interfaces\"\n    },\n    {\n      \"term\": \"orthopedic impairment\"\n    },\n    {\n      \"term\": \"neuroimaging\"\n    }\n  ],\n  \"source_hash\": \"82718dd30da5fff3e627021f515abe47585ee3ac270e56fc45206ea302b9e77d\"\n}","last_activity_at":"2026-05-13 06:39:44","source":"openneuro","source_id":"ds004022","subject_count":7,"modalities":"eeg","age_min":48,"age_max":83,"file_size":665716670,"total_files":64,"tasks":"motorimagery","metadata_columns_error":null,"staleness_warn_stage":null,"staleness_admin_notified_at":null,"authors":"Seho Lee, Hee Ra Jung, In-Nea Wang, Min-Kyung Jung, Hakseung Kim, Dong-Joo Kim","license":"CC0","readme":null,"bids_version":null,"sessions_count":0,"publish_date":"2026-05-13 06:39:44","embedding_dirty":0,"license_tier":"public","zarr_status":"ready","zarr_converted_at":"2026-09-03 12:30:53","zarr_store_count":21,"zarr_index_etag":"36a8d601051d25c7c14c44fe90b6b3ba","zarr_source_commit":"8e31aa5d239e024ba70d568b2c3bbbb73ea697c3","archive_status":"ready","archive_size":570896876,"archive_retry_count":0,"records_status":null,"archive_skip_reason":null,"zarr_errors":0,"zarr_failure_count":0,"zarr_deterministic":0,"zarr_failed_at":null,"num_dataset_citations":2,"num_datapaper_citations":0,"n_channels":18,"electrode_system":null,"has_hed":0,"hed_version":null,"is_exemplar":0,"bytes_present":null,"data_complete":null,"withdrawn_at":null,"withdrawn_reason":null,"archive_complete":null,"archive_absent_files":null,"archive_declared_files":null,"zarr_pool_breaks":0,"total_recording_duration":16920.48,"recording_duration_min":769.92,"recording_duration_max":849.84,"recording_count":21,"recordings_unavailable":0,"recordings_measured":21,"channel_count_min":18,"channel_count_max":18,"sampling_frequency":null,"power_line_frequency":60,"eeg_reference":"FCz","placement_scheme":"extended 10% system","sweep_stamps":"{\"enrichment_updated_at\":\"2026-05-25 00:22:26\",\"metadata_updated_at\":\"2026-05-25 00:22:26\",\"archive_checked_at\":\"2026-06-05 01:33:26\",\"zarr_checked_at\":\"2026-06-07 17:58:43\",\"records_checked_at\":null,\"citations_updated_at\":\"2026-09-10 03:00:19\",\"channel_montage_checked_at\":\"2026-06-28 23:18:30\",\"hed_checked_at\":\"2026-06-30 04:51:02\",\"data_checked_at\":null,\"availability_report_at\":\"2026-07-23 01:16:28\",\"signal_defaults_at\":\"2026-09-02 12:06:21\",\"recording_stats_at\":\"2026-09-04 03:00:31\"}","participants":7,"num_citations":2,"latest_version":"v1.0.0","zarr_verify_status":null,"zarr_verified_at":null,"owner_username":"nemarAdmin","owner_github":"nemarAdmin","file_size_formatted":"635 MB","zarr_data_failures":null,"zarr_index_url":"https://zarr.nemar.org/on004022/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}}
