Motor imagery and action execution [PDF]

, 2020
What triggers the execution of actions? What happens in that moment when an action is triggered? What mental state is there at the moment of action-execution that was not there a second before?

Low intensity focused ultrasound stimulation in stroke: A phase I safety & feasibility trial

Brain Stimulation
Objective: We aimed to determine the maximum safe spatial-peak pulse-average intensity (ISPPA) of low-intensity focused ultrasound stimulation (LIFUS) in stroke patients and explore its effect on motor learning and corticospinal excitability. Methods: We

Effect of Cutaneous Heat Pain on Corticospinal Excitability of the Tibialis Anterior at Rest and during Submaximal Contraction

Neural Plasticity, 2018
Previous studies have shown that pain can interfere with motor control. The neural mechanisms underlying these effects remain largely unknown. At the upper limb, mounting evidence suggests that pain-induced reduction in corticospinal excitability is ...

Effects of Leg Motor Imagery Combined With Electrical Stimulation on Plasticity of Corticospinal Excitability and Spinal Reciprocal Inhibition

Frontiers in Neuroscience, 2019
Motor imagery (MI) combined with electrical stimulation (ES) enhances upper-limb corticospinal excitability. However, its after-effects on both lower limb corticospinal excitability and spinal reciprocal inhibition remain unknown. We aimed to investigate

Corticospinal Excitability Preceding the Grasping of Emotion-Laden Stimuli

PLoS ONE, 2014
Les théories évolutionnistes postulent que les émotions amènent les organismes à agir. Cette étude a examiné si l'excitabilité corticospinale (ECS) est modulée par la valence émotionnelle d'un stimulus à saisir. Le CSE a été estimé sur la base de l'amplitude des potentiels évoqués moteurs (MEP) suscités par la stimulation magnétique transcrânienne (TMS)

The modulatory effect of electrical stimulation on the excitability of the corticospinal tract varies according to the type of muscle contraction being performed

Frontiers in Human Neuroscience, 2014
Afferent input caused by electrical stimulation of a peripheral nerve increases corticospinal excitability during voluntary contractions, indicating that proprioceptive sensory input arriving at the cortex plays a fundamental role in modulating ...

No changes in corticospinal excitability, biochemical markers, and working memory after six weeks of high‐intensity interval training in sedentary males

Physiological Reports, 2019
A single bout of aerobic exercise modulates corticospinal excitability, intracortical circuits, and serum biochemical markers such as brain‐derived neurotrophic factor (BDNF) and insulin‐like growth factor 1 (IGF‐1).

Changes in Magnitude and Variability of Corticospinal Excitability During Rewarded Time-Sensitive Behavior

Frontiers in Behavioral Neuroscience, 2019
Reward expectation and time estimation are important for behavior and affect corticospinal excitability. This study investigated changes in corticospinal excitability during rewarded time-sensitive behavioral tasks.

Effects of Wrist Tendon Vibration on Targeted Upper-Arm Movements in Poststroke Hemiparesis [PDF]

, 2011
Background. Impaired motor control of the upper extremity after stroke may be related to lost sensory, motor, and integrative functions of the brain. Artificial activation of sensory afferents might improve control of movement by adding excitatory drive ...
