Transcutaneous vagus nerve stimulation does not affect verbal memory performance in healthy volunteers [PDF]

, 2020
Introduction: Invasive vagus nerve stimulation (VNS) improves word recognition memory in patients with epilepsy. Recent studies with transcutaneous VNS (tVNS) have also shown positive effects on various subdomains of cognitive functioning in healthy ...

Effectiveness of neuromodulation in patients with drug-resistant epilepsy after failed surgical treatment

Эпилепсия и пароксизмальные состояния
Background. In case of ineffective conservative antiepileptic therapy, surgical treatment aimed at removing the epileptogenic focus may be applied. Resection procedures allow to eliminate seizures in most patients, but in 20–30% cases they persist or ...

Possible relationship between vagus nerve stimulation and ictal discharges revealed by long-term electroencephalographic and electrocorticographic monitoring in a non-responsive patient

Interdisciplinary Neurosurgery, 2021
Background: Vagus nerve stimulation (VNS) is a well-known palliative therapy for refractory epilepsy. However, some non-responsive patients experience persistent epileptic seizures after VNS.

From In‐Silico Optimized Microfabrication to Experimental Validation: Engineering a Tridimensional Epi‐Intraneural Interface

Advanced Functional Materials, EarlyView.
An epi‐intraneural interface is developed through in silico optimization and a novel tridimensional microfabrication pipeline. The device integrates penetrating and epineural contacts on a flexible substrate. Mechanical, electrochemical, and in vivo testing in rat and pig reveal robust implantation, low‐threshold activation, and site‐dependent ...
