Effects of vagal nerve stimulation parameters on heart rate variability in epilepsy patients

Frontiers in Neurology
IntroductionVagal nerve stimulation (VNS) is used as an alternative treatment in drug-resistant epilepsy patients. Effects of VNS on the cardiac autonomic system are controversial.

Growth Rate of the Weight Distribution of Doubly-Generalized LDPC Codes: General Case and Efficient Evaluation

, 2009
The growth rate of the weight distribution of irregular doubly-generalized LDPC (D-GLDPC) codes is developed and in the process, a new efficient numerical technique for its evaluation is presented.

Similarities between the responses to ANT‐DBS and prior VNS in refractory epilepsy

Brain and Behavior, 2018
Neurostimulation has offered new treatment options in refractory epilepsy, first with vagus nerve stimulation (VNS) and more recently with deep brain stimulation (DBS).

Epileptic drop attacks: More than just atonic seizures

Epilepsia Open, EarlyView.
Abstract “Drop attacks” are not officially defined by the International League Against Epilepsy. Seizures are characterized by a sudden loss of control over the trunk and posture, leading to falls and injuries, and resolving within a few seconds. Accurately diagnosing the type of seizure is usually difficult due to limitations in clinical documentation

The Role of the Vagus Nerve in Depressive Disorders: A Literature Review and the Potential of Vagotomy to Create a Depression Phenotype in Rodents

Acta Medica Bulgarica
Major depressive disorder (MDD) affects 280 million people worldwide and is a major global health burden due to its link with suicide, physical comorbidities, and inadequate response to pharmacotherapy in many patients. The monoamine theory of depression

Use of a physiological reflex to standardize vagal nerve stimulation intensity improves data reproducibility in a memory extinction assay

Brain Stimulation, 2021
Background: Modulating brainstem activity, via electrical vagus nerve stimulation (VNS), influences cognitive functions, including memory. However, controlling for changes in stimulus efficacy during chronic studies, and response variability between ...

New error measures and methods for realizing protein graphs from distance data

, 2016
The interval Distance Geometry Problem (iDGP) consists in finding a realization in $\mathbb{R}^K$ of a simple undirected graph $G=(V,E)$ with nonnegative intervals assigned to the edges in such a way that, for each edge, the Euclidean distance between ...

Two-Stage Code Acquisition Employing Search Space Reduction and Iterative Detection in the DS-UWB Downlink [PDF]

, 2008
—In this paper we propose and investigate an iterative code acquisition scheme assisted by both search space reduction and iterative Massage Passing (MP), which was designed for the Direct Sequence-Ultra WideBand (DS-UWB) DownLink (DL).

sEEG‐guided responsive neurostimulation to treat neocortical epilepsy: A multicenter retrospective study of the efficacy and safety of depth electrode‐mediated neuromodulation

Epilepsia Open, EarlyView.
Abstract Objectives Pivotal trials have established the effectiveness of the Responsive Neurostimulation System (RNS® System) in treating focal epilepsy. In clinical trials, depth leads were primarily used to treat mesial temporal seizure onsets while cortical strip leads were used to treat neocortical seizure onsets.

The effect of vagus nerve stimulation on heart rate and respiration rate and their impact on seizure susceptibility in anaesthetized rats under pentylenetetrazol

Frontiers in Neuroscience
Despite the proven efficacy of vagus nerve stimulation (VNS) in seizure control, its precise mechanism of action remains unclear. VNS is known to impact the cardiorespiratory system.
