The effects of expectancy on corticospinal excitability: passively preparing to observe a movement [PDF]
, 2014 [Abstract] The corticospinal tract excitability is modulated when preparing movements. Earlier to movement execution, the excitability of the spinal cord increases waiting for supraspinal commands to release the movement.

Occasional essay: upper motor neuron syndrome in amyotrophic lateral sclerosis [PDF]
, 2020 The diagnosis of amyotrophic lateral sclerosis (ALS) requires recognition of both lower (LMN) and upper motor neuron (UMN) dysfunction.1 However, classical UMN signs are frequently difficult to identify in ALS.2 LMN involvement is sensitively detected ...

Neuromuscular fatigability with repeated exercise in hypoxia: From single‐joint paradigms to sprints
The Journal of Physiology, EarlyView.Abstract figure legend Acute hypobaric or normobaric hypoxic exposure accelerates neuromuscular fatigability during repeated exercise. Indices of peripheral and central fatigue are not different at exhaustion in mild, moderate and severe hypoxia compared with normoxia, but task failure occurs earlier.

Corticospinal excitability during the observation of social behavior
Brain and Cognition, 2013 Evidence suggests that the observation of an action induces in the observers an enhancement of motor evoked potentials (MEPs) recorded by the observer's muscles corresponding to those involved in the observed action. Although this is a well-studied phenomenon, it remains still unclear how the viewer's motor facilitation is influenced by the social ...

Cortical excitability correlates with the event-related desynchronization during brain-computer interface control [PDF]
, 2018 Objective Brain-computer interfaces (BCIs) based on motor control have been suggested as tools for stroke rehabilitation. Some initial successes have been achieved with this approach, however the mechanism by which they work is not yet fully understood ...

Probabilistic Lesion Mapping to Optimize Thalamotomy Targets for Focal Hand Dystonia
Annals of Neurology, Volume 99, Issue 5, Page 1227-1238, May 2026.Objective Focal hand dystonia (FHD) severely impairs task‐specific motor control, yet the optimal surgical target for stereotactic intervention remains uncertain. This study aimed to identify the precise thalamic lesion site associated with symptomatic improvement and to clarify its network connectivity. Methods We retrospectively analyzed 164 patients

Testing rTMS-Induced Neuroplasticity: A Single Case Study of Focal Hand Dystonia [PDF]
, 2018 Focal hand dystonia in musicians is a neurological motor disorder in which aberrant plasticity is caused by excessive repetitive use. This work's purposes were to induce plasticity changes in a dystonic musician through five daily thirty-minute sessions ...

Food Science &Nutrition, Volume 14, Issue 5, May 2026.The review examines the nootropic effects of substances used in sports through their impact on neurotransmission, neuroendocrine control, energy production, synaptic plasticity, and neurovascular connections. The four key neurotransmitters dopamine, acetylcholine, serotonin, and GABA function to control motivation, attention, fatigue perception, and ...

Asymmetry of parietal interhemispheric connections in humans [PDF]
, 2011 Visuospatial abilities are preferentially mediated by the right hemisphere. Although this asymmetry of function is thought to be due to an unbalanced interaction between cerebral hemispheres, the underlying neurophysiological substrate is still largely ...
