Human entorhinal cortex electrical stimulation evoked short‐latency potentials in the broad neocortical regions: Evidence from cortico‐cortical evoked potential recordings

Brain and Behavior, 2019
Objective We aimed at clarifying the clinical significance of the responses evoked by human entorhinal cortex (EC) electrical stimulation by means of cortico‐cortical evoked potentials (CCEPs). Methods We enrolled nine patients with medically intractable

Neonatal Cortical Auditory Evoked Potentials Are Affected by Clinical Conditions Occurring in Early Prematurity [PDF]

, 2015
Purpose: Cortical auditory evoked potentials may serve as an early indicator of developmental problems in the auditory cortex. The aim of the study was to determine the effect on neonatal cortical auditory processing of clinical conditions occurring in ...

Direct Current Auditory Evoked Potentials During Wakefulness, Anesthesia, and Emergence from Anesthesia [PDF]

, 2001
Direct current auditory evoked potentials (DC-AEPs) are a sensitive indicator of depth of anesthesia in ani-mals. However, they have never been investigated in humans. To assess the potential usefulness of DC-AEPs as an indicator of anesthesia in humans,

Pain-motor integration in the primary motor cortex in Parkinson's disease [PDF]

, 2017
In Parkinson's disease (PD), the influence of chronic pain on motor features has never been investigated. We have recently designed a technique that combines nociceptive system activation by laser stimuli and primary motor cortex (M1) activation through ...

Mapping the cortical representation of the lumbar paravertebral muscles [PDF]

, 2007
Objective: The aim of this study was to map the cortical representation of the lumbar spine paravertebral (LP) muscles in healthy subjects. Methods: Transcranial magnetic stimulation (TMS) was employed to map the cortical representations of the LP ...

Clinical utility of contact heat evoked potentials (CHEPs) in a case of mentalis nerve lesion

Clinical Neurophysiology Practice, 2018
Objective: Nociceptive evoked potentials are still infrequently used in electrodiagnostic studies of single patients. We report a case in which the results of contact heat evoked potentials (CHEPs) provided unique information for the diagnosis.

The Objective Method of the Evaluation of the Visual Acuity [PDF]

International Journal of Electronics and Telecommunications, 2019
The paper presents the use of visual evoked potentials VEP to the objective assessment of visual acuity. Methods of using visual evoked potentials (VEP) rely on the assessment of changes of the electrical action potentials generated within the cortex. To

Steady-state visual evoked potentials and phase synchronization in migraine [PDF]

, 2004
We investigate phase synchronization in EEG recordings from migraine patients. We use the analytic signal technique, based on the Hilbert transform, and find that migraine brains are characterized by enhanced alpha band phase synchronization in presence ...

Exploring the Mechanisms of Exercise-Induced Hypoalgesia Using Laser Evoked Potentials

Frontiers in Physiology, 2016
Exercise-induced hypoalgesia is well described, but the underlying mechanisms are unclear. The aim of this study was to examine the effect of exercise on somatosensory evoked potentials, laser evoked potentials, pressure pain thresholds and heat pain ...
