For Type, few-shot examples like “Meta-rdk: Preprocessed EEG data” (visual discrimination) and “Subcortical responses to music and speech…” (auditory stimulus processing) illustrate the convention that datasets focused on sensory stimulus processing are labeled Type=Perception (regardless of response mechanics).","metadata_analysis":"Key available metadata is sparse.

(2) Readme contains no participant/clinical details: \"## Please provide a description for your dataset.\" (3) Only participant count is provided: \"Subjects: 14\". (4) Tasks explicitly suggest somatosensory/electrical stimulation and tactile processing: tasks = [\"Electrical\", \"TactilePerception\"].","paper_abstract_analysis":"No useful paper information.","evidence_alignment_check":"Pathology: Metadata SAYS nothing about a recruited clinical diagnosis (only \"Subjects: 14\" and an empty placeholder readme). Few-shot pattern SUGGESTS labeling specific disorders only when explicitly stated (e.g., Parkinson’s, schizophrenia, epilepsy). ALIGNMENT: insufficient metadata facts to assign a disorder or confirm healthy recruitment; therefore use Unknown.\n\nModality: Metadata SAYS tasks include \"TactilePerception\" and \"Electrical\" (somatosensory stimulation). Few-shot pattern SUGGESTS labeling somatosensory stimulation as Tactile (e.g., Braille tactile stimulation). ALIGNMENT: aligns → Tactile.\n\nType: Metadata SAYS \"TactilePerception\" (explicitly naming perception). Few-shot pattern SUGGESTS sensory processing tasks map to Type=Perception (e.g., visual discrimination labeled Perception; auditory stimulus-response studies labeled Perception). ALIGNMENT: aligns → Perception.","decision_summary":"Pathology top-2: (A) Unknown — supported by lack of any diagnosis/healthy-control statement (\"## Please provide a description for your dataset.\", only \"Subjects: 14\"). (B) Healthy — weak inference from typical placebo/morphine experimental design, but not stated. Winner: Unknown (no explicit recruitment info). Confidence justified by absence of supporting quotes for any pathology.\n\nModality top-2: (A) Tactile — supported by task label \"TactilePerception\" and \"Electrical\" (somatosensory). (B) Other — if “Electrical” were non-sensory (e.g., stimulation not perceived), but the explicit \"TactilePerception\" favors tactile input. Winner: Tactile. Confidence justified by 1 strong explicit task quote + clear few-shot tactile convention.\n\nType top-2: (A) Perception — supported by task label \"TactilePerception\" (explicit). (B) Other — could be pharmacology/analgesia focus, but no metadata states pain/affect/clinical endpoints. Winner: Perception. Confidence justified by explicit task naming + few-shot convention mapping sensory tasks to Perception."}},"computed_title":"Electrical_Morphine_Placebo_2018","nchans_counts":[{"val":66,"count":113}],"sfreq_counts":[{"val":25.0,"count":113}],"stats_computed_at":"2026-04-22T23:16:00.310877+00:00","total_duration_s":null,"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"}}
