Resting-state intracranial high-frequency oscillations and human cognition

Daniel Wendelken, Brian Ervin, Taylor B. Cummins, Anna W. Byars et autres

In 59 drug-resistant epilepsy patients undergoing stereo-electroencephalography, we evaluated relationships between rates of 80-250 Hz high-frequency oscillations (HFO-Rs) and standardized neuropsychological scores. We also quantified how local HFO-Rs modulate functional connectivity among brain regions showing significant HFO-R-cognitive score associations. We hypothesized that …

Stereo‐ EEG mapping of visual working memory with task‐related high‐gamma modulations

Brian Ervin, Jason Buroker, Taylor B. Cummins, Anna W. Byars et autres

OBJECTIVE: We describe a safe, informative, and easy-to-implement approach for presurgical mapping of visual working memory (VWM) with stereo-electroencephalography (SEEG). METHODS: Twenty-four patients with drug-resistant epilepsy, 11-23 years of age, performed a single-probe change detection VWM task, during SEEG monitoring. High-gamma modulations …

Behavior‐ iEEG ‐Spectral‐Power‐Correlation: Defining Neural Substrates of Naturalistic Behavior

Brian Ervin, Clayton Frink, Jason Buroker, Paul S. Horn et autres

OBJECTIVE: Intracranial language localization with electrical stimulation mapping (ESM) and high-gamma modulation (HGM) mapping relies on artificial, repetitive tasks, requiring sustained cooperation from patients. Herein, we tested the validity of unstructured, interpersonal, naturalistic conversation for language localization, using a novel methodology: Behavior-iEEG-Spectral-Power …

Intracranial High-Frequency Oscillations and Epileptogenic Zone: Incorporating Neuroanatomic Variation

Daniel R Wendelken, Brian Ervin, Jason Buroker, Craig Scholle et autres

PURPOSE: To determine if incorporating neuroanatomic or intersubject variation in the occurrence rate of intracranial high-frequency oscillations improves its diagnostic performance for localization of epileptogenic zone (EZ). METHODS: Five minutes of awake stereo-electroencephalography data from 59 patients were analyzed. High-frequency oscillations were …

Chronobiological Spatial Clusters of Cortical Regions in the Human Brain

Ravindra Arya, Gabrielle T. Petito, Jeremy B. Housekeeper, Jason Buroker et autres

PURPOSE: We demonstrate that different regions of the cerebral cortex have different diurnal rhythms of spontaneously occurring high-frequency oscillations (HFOs). METHODS: High-frequency oscillations were assessed with standard-of-care stereotactic electroencephalography in patients with drug-resistant epilepsy. To ensure generalizability of our findings beyond patients …

High‐gamma modulation language mapping and cognitive outcomes after epilepsy surgery

Brian Ervin, Christina Kargol, Anna W. Byars, Jason Buroker et autres

OBJECTIVE: We evaluated changes in cognitive domains after neurosurgical lesioning of cortical sites with significant high-gamma power modulations (HGM) during a visual naming task, although these sites were found language-negative on standard-of-care electrical stimulation mapping (ESM). METHODS: In drug-resistant epilepsy patients who …

Prediction of post-surgical neuropsychological outcomes from high-gamma modulation language mapping and cortical resections (S30.003)

Christina Kargol, Brian Ervin, Clayton Frink, Craig Scholle et autres

Objective: We developed a mathematical model to determine long-term neuropsychological outcomes after epilepsy surgery based on high-gamma modulations during a visual naming task and anatomy of neurosurgical resection. Background: About 30% of patients with epilepsy are drug resistant (DRE) and require surgical …

Neuronal Circuits Supporting Development of Visual Naming Revealed by Intracranial Coherence Modulations

Ravindra Arya, Brian Ervin, Jason Buroker, Hansel M. Greiner et autres

Background: Improvement in visual naming abilities throughout the childhood and adolescence supports development of higher-order linguistic skills. We investigated neuronal circuits underlying improvement in the speed of visual naming with age, and age-related dynamics of these circuits. Methods: Response times were electronically …

Diurnal Periodicity in Spontaneously Occurring High-Frequency Oscillations in Intracranial EEG (P12-5.004)

Gabrielle T. Petito, Jeremy B. Housekeeper, Jason Buroker, Craig Scholle et autres

We studied spontaneously occurring high-frequency oscillations (HFOs) in intracranial EEG (iEEG) for diurnal periodicity.
