DOI: https://doi.org/10.1523/JNEUROSCI.2201-22.2023\n# Task Description\nPatients were resting in the hospital bed, while single pulse stimulation was performed. The stimulation had a duration of 200 microseconds, was biphasic and had an amplitude of 6mA. For subject 7 stimulation amplitude was sometimes reduced to 4mA to minimize interictal responses.\n# Code\nCode to analyses these data is available at: https://github.com/MultimodalNeuroimagingLab/HAPwave\n# Dataset\nThis data is organized according to the Brain Imaging Data Structure specification (BIDS version 1.12.0). A community- driven specification for organizing neurophysiology data along with its metadata. For more information on this data specification, see https://bids-specification.readthedocs.io/en/stable/\nEach subject has their own folder (e.g., ‘sub-01’) containing intracranial EEG (iEEG) recordings from 8 patients during single pulse electrical stimulation, as well as the metadata needed to understand the raw data and event timing.\n# Acknowledgements\nThis project was funded by the National Institute Of Mental Health of the National Institutes of Health Brain Initiative under Award Number R01 MH122258, “CRCNS: Processing speed in the human connectome across the lifespan\". The overall goal of this project is to develop a large database of single pulse stimulation data and develop tools to advance our understanding of the human connectome across the lifespan. The data was collected by Dora Hermes, Nick Gregg, Brian Lundstrom, Cindy Nelson, Gabriela Ojeda Valencia, Gregg Worrell and Kai J. Miller.

Another relevant few-shot by population clue is the pediatric epilepsy HFO dataset, which labels Pathology=\"Epilepsy\" when epilepsy is explicit and uses Clinical/Intervention when the goal is biomarker/clinical neurophysiology rather than a cognitive task. These examples guide (1) mapping stimulation paradigms to Modality=\"Other\" and (2) mapping epilepsy-linked patient iEEG contexts to Pathology=\"Epilepsy\" when supported by metadata terms (e.g., interictal).","metadata_analysis":"Key metadata facts: (1) clinical iEEG + patients: \"This dataset contains intracranial EEG (iEEG) recordings from 8 patients during single pulse electrical stimulation\". (2) no behavioral task, patient resting: \"Patients were resting in the hospital bed, while single pulse stimulation was performed.\" (3) epilepsy-specific term suggesting epilepsy monitoring context: \"stimulation amplitude was sometimes reduced ... to minimize interictal responses.\"","paper_abstract_analysis":"No useful paper information.","evidence_alignment_check":"Pathology — Metadata says: \"8 patients\" with iEEG and mentions \"interictal responses\" (epilepsy-specific clinical term). Few-shot pattern suggests intracranial stimulation datasets are typically from epilepsy monitoring/surgical evaluation cohorts; this ALIGNS with the interictal wording, so Epilepsy is selected.\nModality — Metadata says stimulus is \"single pulse electrical stimulation\" while patients rest; no auditory/visual/tactile sensory stimuli are described. Few-shot convention (SEP stimulation example) maps direct stimulation paradigms to Modality=\"Other\"; this ALIGNS.\nType — Metadata says they were \"resting\" but the core manipulation is single-pulse stimulation to study \"network interactions\" (connectome/clinical neurophysiology), not an eyes-open/closed resting-state study. Few-shot conventions: stimulation/procedure-focused datasets are typically labeled Clinical/Intervention or Other rather than Resting-state; this mostly ALIGNS, with minor ambiguity versus \"Other\".","decision_summary":"Pathology top-2: (A) Epilepsy — supported by \"intracranial EEG (iEEG) recordings from 8 patients\" plus the epilepsy-specific phrase \"minimize interictal responses\"; (B) Surgery — plausible because iEEG/stimulation occurs in a hospital clinical workflow but not explicitly stated as intraoperative. Winner: Epilepsy (interictal wording is stronger epilepsy evidence). Confidence=0.7 (one strong explicit epilepsy-linked term + patient iEEG context).\nModality top-2: (A) Other — supported by \"single pulse electrical stimulation\" (not a sensory channel); (B) Resting State — plausible because \"Patients were resting\" but stimulation is the dominant input. Winner: Other. Confidence=0.8 (2 clear quotes about stimulation + strong few-shot convention match).\nType top-2: (A) Clinical/Intervention — supported by patient iEEG, hospital-bed stimulation, and network mapping aim; (B) Other — plausible because it is mechanistic network physiology rather than an intervention trial. Winner: Clinical/Intervention. Confidence=0.7 (one clear task-context quote + clinical procedure framing, but some ambiguity vs Other)."}},"nemar_citation_count":1,"computed_title":"HAPwave_bids","nchans_counts":[{"val":201,"count":1},{"val":178,"count":1},{"val":256,"count":1},{"val":226,"count":1},{"val":194,"count":1},{"val":192,"count":1},{"val":207,"count":1},{"val":244,"count":1}],"sfreq_counts":[{"val":2048.0,"count":8}],"stats_computed_at":"2026-04-21T23:17:03.730380+00:00","total_duration_s":32840.41796875,"author_year":"Valencia2023","canonical_name":null}}
