All participants had normal or corrected vision and hearing, apart from sub-16.\n### Task\nThe task consisted of imagining and perceiving stimuli from three modalities; visual pictorial, visual orthographic (writing) or auditory. Each of the stimuli belonged to one of three categories: guitar, flower and penguin. These categories were selected based on being semantically dissimilar to one another, and because there were all of 2 syllables.\n### Dataset Versions\nThe dataset provided consists of the raw EEG data, a pre-processed version, and an epoched version.","recording_modality":["eeg"],"senior_author":"Eamonn O'Neill","sessions":["01","02","03"],"size_bytes":686761341,"source":"openneuro","study_design":null,"study_domain":null,"tasks":["experiment"],"timestamps":{"digested_at":"2026-04-22T12:26:26.643791+00:00","dataset_created_at":"2022-10-25T17:34:10.377Z","dataset_modified_at":"2023-09-27T14:44:14.000Z"},"total_files":15,"storage":{"backend":"s3","base":"s3://openneuro.org/ds004306","raw_key":"dataset_description.json","dep_keys":["CHANGES","README","participants.json","participants.tsv"]},"nemar_citation_count":1,"computed_title":"EEG Semantic Imagination and Perception Dataset","nchans_counts":[{"val":128,"count":15}],"sfreq_counts":[{"val":1024.0,"count":15}],"stats_computed_at":"2026-04-22T23:16:00.307347+00:00","tags":{"modality":"Multisensory","pathology":"Healthy","type":"Perception"},"total_duration_s":65459.5205078125,"author_year":"Wilson2022","canonical_name":null}}
