Acute and persistent changes in neural oscillatory activity predict development of epilepsy following acute organophosphate intoxication in adult rats

Epilepsia, Volume 66, Issue 4, Page 1329-1342, April 2025.
Abstract Objective Acute organophosphate (OP) intoxication affects a significant number of individuals worldwide. Those who survive OP‐induced cholinergic crisis, which includes status epilepticus, often develop neurological morbidities. Here, we provide a rigorous characterization of the acute and delayed electrophysiological responses to OP ...

Reducing ECG Artifact From Left Ventricular Assist Device Electromagnetic Interference

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2020
Background Left ventricular assist devices (LVADs) generate electromagnetic interference that causes high‐frequency noise artifacts on 12‐lead ECGs. We describe the causes of this interference and potential solutions to aid ECG interpretation in patients

Human cortical high‐gamma power scales with movement rate in healthy participants and stroke survivors

The Journal of Physiology, Volume 603, Issue 4, Page 873-893, 15 February 2025.
Abstract figure legend Magnetoencephalography data from stroke survivors, healthy, age‐matched control participants and healthy young participants were measured during the execution of a thumb movement task. Movement‐related high‐gamma power was evident in all three groups with a maximum over motor cortical areas contralateral to the performed movement.
