Parietal conditioning enhances motor surround inhibition

Brain Stimulation, 2020
Background: Motor surround inhibition (mSI) is a phenomenon supportive for executing selective finger movements, wherein synergist muscles are selectively facilitated while surround muscles are inhibited.

Multimodal imaging of essential tremor and dystonic tremor

NeuroImage: Clinical, 2022
Despite recent advances in tremor and dystonia classification, it remains difficult to discriminate essential tremor from dystonic tremor as they are similar in appearance and no biomarker exists.

Functional Impact of Sydenham's Chorea: A Case Report

Tremor and Other Hyperkinetic Movements, 2013
Background: Sydenham's chorea (SC) is the most common type of acquired chorea in childhood. In some cases, symptoms (most commonly described in terms of neurological signs) last up to 2 years, and many cases relapse.

BacAv, a new free online platform for clinical back-averaging

Clinical Neurophysiology Practice, 2020
Objective: The back-average technique is very useful to study the relation between the activity in the cortex and the muscles. It has two main clinical applications, Bereitschaftspotential (BP) recording and myoclonus studies.

Inter-Individual Variability in Motor Output Is Driven by Recruitment Gain in the Corticospinal Tract Rather Than Motor Threshold

Brain Sciences, 2022
Variability in the response of individuals to various non-invasive brain stimulation protocols is a major problem that limits their potential for clinical applications. Baseline motor-evoked potential (MEP) amplitude is the key predictor of an individual’

Dissociative Motor Disorder

Indian Journal of Psychological Medicine, 2017
Conversion disorders are more prevalent in childhood and adolescence, especially in females. They are usually associated with stressors and symptoms usually reflect a means to avoid the stressor, or also with a primary and secondary gain. This case report involves a similar situation where a young girl was treated successfully with diazepam ...

Response repetition biases in human perceptual decisions are explained by activity decay in competitive attractor models

eLife, 2016
Animals and humans have a tendency to repeat recent choices, a phenomenon known as choice hysteresis. The mechanism for this choice bias remains unclear.

Enhanced Motivational Modulation of Motor Behaviour with Subthalamic Nucleus Deep Brain Stimulation in Parkinson’s Disease

Parkinson's Disease, 2019
Background. Motivational improvement of movement speed in Parkinson’s disease (PD) is observed in life-threatening situations and has been empirically demonstrated in experimental studies using reaction time paradigms. Objectives.

Variability and Predictors of Response to Continuous Theta Burst Stimulation: A TMS-EEG Study

Frontiers in Neuroscience, 2018
Continuous theta-burst stimulation (cTBS) is a repetitive transcranial magnetic stimulation paradigm reported to decrease the excitability of the stimulated cortical area and which is thought to reflect a form of inhibitory synaptic plasticity.

The Immediate and Short-Term Effects of Transcutaneous Spinal Cord Stimulation and Peripheral Nerve Stimulation on Corticospinal Excitability

Frontiers in Neuroscience, 2021
Rehabilitative interventions involving electrical stimulation show promise for neuroplastic recovery in people living with Spinal Cord Injury (SCI). However, the understanding of how stimulation interacts with descending and spinal excitability remain ...
