The primary cue\nwas preceeded by a visual pre-cue and an auditory pre-cue, which occurred at the same time (500ms before arrow cue).\nEach trial had either standard for both pre-cues, oddball visual pre-cue, or oddball auditory pre-cue.\nOur analysis focused only on trials with both pre-cues standard or oddball auditory pre-cue.","recording_modality":["eeg"],"senior_author":"Nandakumar Narayanan nandakumar-narayanan@uiowa.edu","sessions":[],"size_bytes":14469987580,"source":"openneuro","study_design":null,"study_domain":null,"tasks":["Oddball"],"timestamps":{"digested_at":"2026-04-22T12:26:42.692725+00:00","dataset_created_at":"2023-05-24T16:38:44.641Z","dataset_modified_at":"2023-05-24T17:01:42.000Z"},"total_files":146,"storage":{"backend":"s3","base":"s3://openneuro.org/ds004574","raw_key":"dataset_description.json","dep_keys":["CHANGES","README","participants.json","participants.tsv","task-Oddball_events.json"]},"nemar_citation_count":1,"computed_title":"Cross-modal Oddball Task.","nchans_counts":[{"val":63,"count":116},{"val":64,"count":29},{"val":66,"count":1}],"sfreq_counts":[{"val":500.0,"count":146}],"stats_computed_at":"2026-04-22T23:16:00.307947+00:00","tags":{"modality":"Multisensory","pathology":"Parkinson's","type":"Clinical/Intervention"},"total_duration_s":111754.4,"author_year":"Singh2023_Cross_modal","canonical_name":null}}
