The closest example involves the Parkinson's dataset, where a clinical intervention involving sensory modalities and physiological response to stimuli was labeled as 'Clinical/Intervention' for Type. While the Parkinson's dataset involved multisensory input and metrics of cognitive functioning, the 'Electrical_Morphine_Placebo_2018' dataset involves morphine as a pharmacological factor and electrical stimuli aimed at measuring physiological responses, thus fitting into the 'Clinical/Intervention' label for research into anesthetics or pain modulation.","metadata_analysis":"The dataset is titled 'Electrical_Morphine_Placebo_2018' with a detailed description mentioning authors focused on morphine's effects as reflected in a Frontiers in Human Neuroscience publication. The participant group includes those under morphine and placebo conditions. Events types, 'Electrical VAS 3' and 'Electrical VAS 7', suggest an experimental approach involving pain thresholds or perception measures, hinting at an intervention-focused paradigm involving sensory input.","paper_abstract_analysis":"No useful paper information.","evidence_alignment_check":"1. Pathology: Metadata SAYS it's investigating morphine effects (likely pharmacological or sensory study without a specified pathology) → Suggests Healthy or Other if linked to non-pathological sensory studies. 2. Modality: Metadata describes 'Electrical' stimuli, aligning with Tactile modality suggested by electric stimuli affecting perception. 3. Type: The focus on morphine and placebo response is consistent with Clinical/Intervention type. Few-shot suggests similar intervention context → Matches Clinical/Intervention.","decision_summary":"Pathology: Runner-up labels were Healthy and Other due to generic pharmacological study scope without a patients' cohort. Selected Healthy because there is no explicit clinical population. Modality: Chooses Tactile for clear evidence of electrical stimulation, aligning with sensory manipulation patterns. Type: Clearly aligns with Clinical/Intervention due to intervention method involving morphine/placebo and its evaluation. Confidence sourced from task alignment with paradigms and interventions described in parallel literature."}},"computed_title":"Electrical_Morphine_Placebo_2018","nchans_counts":[{"val":66,"count":113}],"sfreq_counts":[{"val":25.0,"count":113}],"stats_computed_at":"2026-05-31T19:34:32.601823+00:00","total_duration_s":44388.0,"canonical_name":null,"name_confidence":0.58,"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":"Peng2025","bad_channels_info":null,"acknowledgements":"This work was supported by the National Institutes of Health (NIH), the National Institute of General Medical Sciences (NIGMS) under grants NIH-NIGMS 1-R01-GM104986, 1-R01-GM122405, and the Mayday Fund, New York.
