Each electrode has 10 leads evenly spaced 3-7mm apart. \r\n\r\nWith the exception of patients SD012 and SD022, all implants are depth electrodes. Patients SD012 and SD022 had grid and strip electrodes implanted in addition to several depth electrodes.\r\n\r\nAny channel names beginning with ``C'' were not used and should be dropped from analyses.\r\n\r\nTASK\r\n\r\nParticipants passively listened to 30-45s passages of conversational speech and  verbally answered a 2AC content question after each passage. 6 blocks with 7 passages per block.\r\n\r\nMISSING DATA\r\n\r\nAnatomical scans for particpant SD012 are not available due to excessive movement artifacts.\r\n","bids_version":"1.6.0","sessions_count":2,"publish_date":null,"embedding_dirty":0,"license_tier":"public","zarr_status":"ready","zarr_converted_at":"2026-08-13 23:33:40","zarr_store_count":7,"zarr_index_etag":"406abe035fc1f7fe9d1c0d308cb5e317","zarr_source_commit":"b66dcebba3a87ea4d01004c9956ceba1d4216994","archive_status":"ready","archive_size":8699915388,"archive_retry_count":0,"records_status":"ready","archive_skip_reason":null,"zarr_errors":4,"zarr_failure_count":4,"zarr_deterministic":1,"zarr_failed_at":"2026-08-13 23:33:40","num_dataset_citations":0,"num_datapaper_citations":0,"n_channels":null,"electrode_system":null,"has_hed":0,"hed_version":null,"is_exemplar":0,"bytes_present":13940356006,"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":21019.811999999998,"recording_duration_min":1146.5,"recording_duration_max":4687.5,"recording_count":11,"recordings_unavailable":4,"recordings_measured":7,"channel_count_min":148,"channel_count_max":278,"sampling_frequency":null,"power_line_frequency":null,"eeg_reference":null,"placement_scheme":null,"sweep_stamps":"{\"enrichment_updated_at\":\"2026-06-25 08:13:03\",\"metadata_updated_at\":\"2026-06-25 08:13:10\",\"archive_checked_at\":\"2026-06-25 08:20:46\",\"zarr_checked_at\":null,\"records_checked_at\":\"2026-06-25 08:14:45\",\"citations_updated_at\":null,\"channel_montage_checked_at\":\"2026-06-28 23:32:19\",\"hed_checked_at\":\"2026-06-30 05:05:07\",\"data_checked_at\":\"2026-08-14 03:00:42\",\"availability_report_at\":\"2026-07-23 01:20:32\",\"recording_stats_at\":\"2026-09-02 11:32:55\",\"signal_defaults_at\":\"2026-09-02 12:19:30\"}","participants":10,"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":"13.20 GB","zarr_data_failures":{"count":4,"detail_ref":"zarr/index.json","compacted_by":"migration_0074"},"zarr_index_url":"https://zarr.nemar.org/on004703/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}}
