However, the dataset at hand involves an 'n-back' task, potentially linked to cognitive assessment similar to working memory in healthy participants as seen in other datasets, like 'EEG, pupillometry, ECG and photoplethysmography, and behavioral data in the digit span task and rest'.","metadata_analysis":"The metadata for the given dataset provides minimal details. The 'Name: ODE' and its association with 'nback' suggest a potential focus on cognitive functions such as working memory or attention, commonly assessed using n-back tasks, but no explicit participant population or modality is clearly mentioned.","paper_abstract_analysis":"No useful paper information.","evidence_alignment_check":"For pathology, the metadata lacks specifics on participant demographics, suggesting more likely a 'Healthy' sample, as commonly expected when no condition is defined. No conflicting evidence from the few-shot is present. For modality, without specific mention of visual, auditory, or multisensory stimuli the assignment remains 'Unknown'. For type, 'nback' strongly suggests a cognitive function focus such as 'Attention' or 'Memory', given common usage of n-back tasks in cognitive assessment — alignment with few-shot examples points towards 'Memory' as n-back tasks are often used for such purposes.","decision_summary":"The metadata suggests: Pathology aligns with 'Healthy' due to lack of explicit clinical population. Modality remains 'Unknown' due to insufficient data on stimuli. Type aligns with 'Memory' due to the task being 'nback', which often involves working memory tests in healthy cohorts. Confidence higher for pathology given clear alignment pattern, less for modality and type due to lack of explicit details."}},"nemar_citation_count":0,"computed_title":"ODE","nchans_counts":[{"val":64,"count":1}],"sfreq_counts":[{"val":128.0,"count":1}],"stats_computed_at":"2026-05-31T19:34:32.600050+00:00","total_duration_s":1926.1796875,"canonical_name":null,"name_confidence":0.18,"name_meta":{"suggested_at":"2026-04-14T10:18:35.343Z","model":"openai/gpt-5.2 + openai/gpt-5.4-mini + deterministic_fallback"},"name_source":"author_year","author_year":"Johnson2023_ODE","bad_channels_info":null,"references_and_links":[""]}}
