Corticospinal excitability across lower limb muscles in humans
Journal of Neurophysiology, 2023We provide evidence on how corticospinal output differs across muscles in the leg in intact humans. We found that corticospinal responses were larger in a distal intrinsic foot muscle and were smaller in the biceps femoris compared to all other muscles in the leg.

Assessing Corticospinal Excitability During Goal-Directed Reaching Behavior
Journal of Visualized Experiments, 2022Reaching is a widely studied behavior in motor physiology and neuroscience research. While reaching has been examined using a variety of behavioral manipulations, there remain significant gaps in the understanding of the neural processes involved in reach planning, execution, and control.

Dynamic changes in corticospinal excitability during motor imagery
Experimental Brain Research, 1999We investigated temporal changes in the amplitudes of motor-evoked potentials (MEPs) induced by transcranial magnetic stimulation over the left motor cortex during motor imagery. Nine subjects were instructed to imagine repetitive wrist flexion and extension movements at 1 Hz, in which the flexion timing was cued by a tone signal.

Modulation of Corticospinal Excitability with Contralateral Arm Cycling
Neuroscience, 2020This is the first study to examine the influence of activity in one limb on corticospinal excitability to the contralateral limb during a locomotor output. Corticospinal and spinal excitability to the biceps brachii of the ipsilateral arm were assessed using transcranial magnetic stimulation (TMS) of the motor cortex and transmastoid electrical ...

Vibration-Induced Kinesthetic Illusions and Corticospinal Excitability Changes
Journal of Motor Behavior, 2016The authors' aim was to investigate the changes of corticospinal excitability during kinesthetic illusions induced by tendon vibration. Motor-evoked potentials in response to transcranial magnetic stimulation were recorded from the vibrated flexor carpi radialis and its antagonist, extensor carpi radialis.

Corticospinal excitability changes following downhill and uphill walking
Experimental Brain Research, 2019Locomotor exercise may induce corticospinal excitability and/or cortical inhibition change in the knee extensors. This study investigated whether the mode of muscle contraction involved during a locomotor exercise modulates corticospinal and intracortical responsiveness.

Increased corticospinal excitability induced by unpleasant visual stimuli
Neuroscience Letters, 2010Pleasant and unpleasant emotional stimuli are frequently conceptualized as motivators for action. This notion was examined using focal transcranial magnetic stimulation (TMS). Ten healthy participants viewed pleasant, neutral, and unpleasant pictures from the International Affective Picture System (IAPS).

Corticospinal excitability changes following prolonged muscle tendon vibration
NeuroReport, 2003The present experiment addressed the time course of corticospinal excitability changes following interventional muscle tendon vibration. Using transcranial magnetic stimulation, motor evoked potentials of the flexor carpi radialis and extensor carpi radialis brevis muscle were recorded for a period of 60 min after cessation of vibration (80 Hz, 0.5 mm,

Lower limb immobilization is associated with increased corticospinal excitability
Experimental Brain Research, 2007Temporary immobilization of the leg serves as a useful model for the brain's adaptive responses to casting, long-term confinement to bed rest and possibly to trauma. As part of a larger program using TMS to investigate changes associated with bed rest, we sought to determine whether casting of the leg causes brain excitability changes measurable with ...
