That example shows that when the dataset goal is largely methodological/recording-optimization around evoked responses (SEP) rather than a cognitive construct, the catalog convention is to use Type=\"Other\" rather than \"Perception\". A secondary match is \"Braille letters - EEG\" (Other / Tactile / Learning), which supports using Modality=\"Tactile\" when stimuli are delivered to somatosensory receptors (here: whiskers).","metadata_analysis":"Key facts from the provided README: (1) population/context: \"DISC were implanted in rat somatosensory cortex.\" (non-human, implanted device validation context). (2) state and stimulus: \"While anesthetized, whiskers were being stimulated using an air puffer.\" (tactile whisker stimulation, under anesthesia). (3) purpose framing: \"Project Title: DISC Validation in Rat Somatosensory Cortex\" (suggests methodological/validation focus rather than a cognitive construct).","paper_abstract_analysis":"No useful paper information. (Only a biorxiv link is provided; no abstract text included in metadata.)","evidence_alignment_check":"Pathology: Metadata says \"rat\" and \"implanted\" but no disease/diagnosis; few-shot patterns label non-standard/non-clinical populations as \"Other\" (e.g., visually deprived braille study). ALIGN.\nModality: Metadata says \"whiskers ... stimulated using an air puffer\" (somatosensory/tactile input). Few-shot braille example maps somatosensory stimulation to \"Tactile\". ALIGN.\nType: Metadata emphasizes \"DISC Validation\" and anesthesia with whisker stimulation; few-shot intraoperative SEP example suggests methodological evoked-response/recording validation is Type=\"Other\" rather than a cognitive construct label. ALIGN (leans to Other over Perception).","decision_summary":"Pathology top-2: (1) Other — supported by \"rat\" population and no clinical recruitment: \"DISC were implanted in rat somatosensory cortex.\" (2) Healthy — plausible because no disorder is mentioned, but conventionally \"Healthy\" is used for normative human cohorts; here it is non-human/device-validation. Final: Other. Evidence alignment: aligned with few-shot convention. Confidence=0.7 (one clear quote supports non-clinical, but limited participant metadata).\nModality top-2: (1) Tactile — \"whiskers were being stimulated using an air puffer.\" (2) Anesthesia — anesthesia is present (\"While anesthetized\"), but anesthesia is a state not the stimulus channel; stimulus channel is tactile. Final: Tactile. Confidence=0.8 (two explicit quotes: whiskers + air puffer; plus strong few-shot analog to tactile stimulation).\nType top-2: (1) Other — project framed as validation: \"DISC Validation in Rat Somatosensory Cortex\" and implanted device context; resembles methodological SEP-style datasets. (2) Perception — could be considered somatosensory processing due to whisker stimulation, but no behavioral/perceptual task and anesthesia reduces a cognition framing. Final: Other. Confidence=0.7 (one explicit quote indicating validation focus; limited task/event detail)."}},"nemar_citation_count":1,"computed_title":"Somatosensory Cortex Rat DISC Data","nchans_counts":[{"val":128,"count":28},{"val":104,"count":9},{"val":102,"count":9},{"val":110,"count":9},{"val":112,"count":9},{"val":105,"count":6},{"val":106,"count":2},{"val":111,"count":1}],"sfreq_counts":[{"val":20000.0,"count":73}],"stats_computed_at":"2026-04-22T23:16:00.307111+00:00","total_duration_s":null,"author_year":"Abrego2022","canonical_name":null}}
