Transcranial magnetic and electrical stimulation compared: Does TES activate intracortical neuronal circuits?

open access: closedClinical Neurophysiology, 2005
To determine whether, and under which conditions, transcranial electrical stimulation (TES) and transcranial magnetic stimulation (TMS) can activate similar neuronal structures of the human motor cortex, as indicated by electromyographic recordings.Focal TMS was performed on three subjects inducing a postero-anterior directed current (p-a), TES with ...

Transcranial electrical stimulation of the occipital cortex during visual perception modifies the magnitude of BOLD activity: A combined tES–fMRI approach

open access: closedNeuroImage, 2015
The aim of this study was to investigate if the blood oxygenation level-dependent (BOLD) changes in the visual cortex can be used as biomarkers reflecting the online and offline effects of transcranial electrical stimulation (tES). Anodal transcranial direct current stimulation (tDCS) and 10Hz transcranial alternating current stimulation (tACS) were ...

P495: Selective loss of the D-wave evoked by contralateral hemispheric transcranial electric stimulation (TES)

Clinical Neurophysiology, 2014
Methods: Description of a case series. Eight NF1 patients underwent interventions in order to remove spinal roots neurofibromas causing cervical spinal cord compression. A second intervention at the lumbosacral spine was necessary to remove neurofibromas located at the cauda equina in 2 cases.

S 1 New methods for electrode optimization for high-definition transcranial electric stimulation (hd-tES)

Clinical Neurophysiology, 2017
Background/problem description tES is a non-invasive brain stimulation technique which modifies neural excitability by providing weak currents through scalp electrodes. The aim of my presentation is to introduce and analyze new forward and inverse simulation methods for safe and well-targeted multi-electrode tES. Methods Continuous Galerkin Finite
