However, the few-shots illustrate two relevant catalog conventions: (1) when the dataset is primarily about a physiological/clinical manipulation or biomarker in a non-cognitive protocol, the Type tends to be labeled \"Clinical/Intervention\" (e.g., the dementia resting-state cohort labeled Clinical/Intervention rather than Resting-state as a research aim). (2) Modality labels reflect the dominant state/input manipulation rather than responses; here the dominant manipulation is sedation/anesthetic drugs, so we follow the same principle and use the dedicated \"Anesthesia\" modality label (no close few-shot exists, but this follows the catalog’s stimulus/state-driven modality convention).","metadata_analysis":"Key metadata facts: (1) This is an animal sedation/anesthesia and ischemia model: \"This sedation, ischemia, recovery experiment contains 11 animals (juvenile pigs).\" (2) The main experimental manipulations are anesthetic/analgesic sedation levels and induced ischemia: \"monitored under sedation states 1-5 (isoflurane, fentanyl, propofol), followed by 1 or 2 episodes of gradual ischemia\" and \"Two crude groups are indicated: 1) sedation - animals had no ischemia and 2) ischemia - animals had sedation, followed by ischemia episodes and followed by recovery.\" (3) Surgical instrumentation is part of the protocol: \"Animals were surgically instrumented\".","paper_abstract_analysis":"No useful paper information.","evidence_alignment_check":"Pathology: Metadata SAYS it is an animal model with induced ischemia and surgery (\"11 animals (juvenile pigs)\", \"surgically instrumented\", \"episodes of gradual ischemia\"). Few-shot pattern SUGGESTS that when there is a disease cohort (e.g., Parkinson’s, dementia) use that pathology label; here there is no recruited human clinical cohort. ALIGNMENT: partial—there is a medical manipulation but not a standard human diagnosis label; therefore use a non-diagnostic bucket.\n\nModality: Metadata SAYS sedation/anesthetic drugs are central (\"sedation states 1-5 (isoflurane, fentanyl, propofol)\"). Few-shot pattern SUGGESTS modality should reflect dominant input/state condition (e.g., Sleep vs Resting State vs Auditory). ALIGNMENT: yes—this supports choosing \"Anesthesia\".\n\nType: Metadata SAYS the study is about physiological communication under drug-induced sedation and ischemia/recovery rather than a cognitive task (\"sedation, ischemia, recovery experiment\"; no task/stimulus paradigm described). Few-shot pattern SUGGESTS labeling such manipulation-focused datasets as \"Clinical/Intervention\" (e.g., dementia dataset labeled Clinical/Intervention as primary aim). ALIGNMENT: yes—primary purpose is intervention/manipulation effects on brain function.","decision_summary":"Top-2 candidates per category:\n\nPathology: (1) Other — supported by \"11 animals (juvenile pigs)\", \"surgically instrumented\", and induced \"gradual ischemia\" (not a standard human recruited diagnosis in the allowed list). (2) Surgery — supported by \"Animals were surgically instrumented\", but surgery is procedural and not clearly the recruited condition; ischemia is the modeled condition. Winner: Other. Alignment: few-shot conventions don’t provide a direct pathology mapping for animal ischemia; metadata facts dominate.\n\nModality: (1) Anesthesia — supported by \"sedation states 1-5 (isoflurane, fentanyl, propofol)\" and the protocol being explicitly a \"sedation, ischemia, recovery experiment\". (2) Unknown — if one treated this as non-stimulus physiological recording without a modality; but the dataset explicitly centers anesthesia/sedation. Winner: Anesthesia. Alignment: matches modality-by-state convention.\n\nType: (1) Clinical/Intervention — supported by the intervention/manipulation focus: sedation drugs, induced ischemia, recovery (\"sedation... followed by ... gradual ischemia ... and recovery\"), and lack of a cognitive task. (2) Other — if treated as basic physiology/animal model outside clinical framing. Winner: Clinical/Intervention, consistent with few-shot convention that primary purpose being a physiological/clinical manipulation leads to Clinical/Intervention.\n\nConfidence basis: Pathology confidence is moderate because it’s clearly non-healthy/medical manipulation but not a named allowed diagnosis; Modality and Type have direct supporting quotes."}},"canonical_name":[],"name_confidence":0.62,"name_meta":{"suggested_at":"2026-04-14T10:18:35.342Z","model":"openai/gpt-5.2 + openai/gpt-5.4-mini + deterministic_fallback"},"name_source":"author_year","author_year":"Frasch2020","size_human":"19.7 MB"}}
