Visual and somatosensory evoked potentials abnormalities among Behçet’s disease patients and their relation to disease activity, severity and antiphospholipid antibodies: a cross-sectional study

Egyptian Rheumatology and Rehabilitation
Background Behçet’s disease (BD) is a common disease with high morbidity and mortality. Ocular, neurological, and vascular affection in BD are a major cause of such morbidity and mortality. Evoked potential (EP) studies including visual evoked potentials

NeuroSense: A non-invasive and configurable somatosensory stimulator with OPENVIBE communication

HardwareX
Understanding the somatosensory system and its abnormalities requires the development of devices that can accurately stimulate the human skin. New methods for assessing the somatosensory system can enhance the diagnosis, treatments, and prognosis for ...

A Randomized, Sham‐Controlled Trial of Repetitive Transcranial Magnetic Stimulation Targeting M1 and S2 in Central Poststroke Pain: A Pilot Trial

Neuromodulation: Technology at the Neural Interface, EarlyView., 2021
Abstract Objectives Central poststroke pain (CPSP), a neuropathic pain condition, is difficult to treat. Repetitive transcranial magnetic stimulation (rTMS) targeted to the primary motor cortex (M1) can alleviate the condition, but not all patients respond. We aimed to assess a promising alternative rTMS target, the secondary somatosensory cortex (S2),

Electrophysiological Evidence for Impaired Central Pain Modulation in Parkinson's Disease

Movement Disorders, EarlyView.
Our study demonstrates electrophysiological evidence of impaired central pain modulation in Parkinson's disease (PD) patients using laser‐evoked potential habituation and quantitative sensory testing. PD patients exhibited reduced habituation to painful stimuli, independent of reported pain or medication.

The Wire Is Not the Territory: Understanding Representational Drift in Olfaction With Dynamical Systems Theory

Topics in Cognitive Science, EarlyView., 2023
Abstract Representational drift is a phenomenon of increasing interest in the cognitive and neural sciences. While investigations are ongoing for other sensory cortices, recent research has demonstrated the pervasiveness in which it occurs in the piriform cortex for olfaction.

Somato‐Cognitive Action Network in Focal Dystonia

Movement Disorders, EarlyView.
Abstract Background The central pathology causing idiopathic focal dystonia remains unclear. The recently identified somato‐cognitive action network (SCAN) has been implicated. Objective We tested whether the effector‐agnostic SCAN may constitute a central pathology shared across dystonia subtypes, whereas the effector‐specific regions in the primary ...

Vagus Nerve Stimulation in Movement Disorders, from Principles to a Systematic Review of Evidence

Movement Disorders, EarlyView.
Abstract Background The vagus nerve (VN), the principal component of the parasympathetic branch of the autonomic nervous system (ANS), mediates bidirec communication between the central nervous system (CNS) and peripheral organs. Vagus nerve stimulation (VNS), delivered through invasive (iVNS) or non‐invasive (transcutaneous cervical [tcVNS] and ...

Predictive Performance of Machine Learning with Evoked Potentials for SCI and MS Prognosis: A Meta-Analysis

Clinical and Translational Neuroscience
Evoked potentials (EPs), including somatosensory evoked potentials (SSEPs) and motor evoked potentials (MEPs), are used to assess neural conduction in spinal cord injury (SCI) and multiple sclerosis (MS), conditions marked by demyelination, inflammation,

The Second Hit Hypothesis in Animal and Human Dystonia: The Role of Peripheral Nerve Trauma and Spinal Cord Injury

Movement Disorders, EarlyView.
The “second‐hit” hypothesis proposes that both a genetic predisposition and an environmental insult—such as peripheral nerve trauma or spinal cord injury—are required for dystonia development. This review explores how neuroinflammation and maladaptive plasticity, triggered by nerve and spinal cord injury, contribute to dystonia pathogenesis.

A Network Centered on the Visual‐Motor Cortex Is Critically Involved in Postural Abnormality in Parkinson's Disease

Movement Disorders, EarlyView.
Abstract Background Postural abnormality (PA) is a key motor symptom in Parkinson's disease (PD) that leads to disability and death. However, the pathophysiology underlying PA is still unknown. Objective The objective of this study was to explore the neural patterns behind PAs and measures toward functional restoration using repetitive transcranial ...
