Excitability Changes in the Human Primary Motor Cortex During Observation with Motor Imagery of Chopstick Use
[Purpose] The aim of this study was to investigate whether the performance of a combination of observation and motor imagery of chopstick use (complex task) increased corticospinal excitability more than the performance of observation alone. [Subjects and Methods] We recruited 10 healthy subjects with no history of neurological diseases. Corticospinal excitability was assessed with the particip...
متن کاملThe relationship between corticospinal excitability during motor imagery and motor imagery ability.
It is commonly reported that transcranial magnetic stimulation (TMS) of the motor cortex during action observation and motor imagery results in increases in the amplitude of motor evoked potentials (MEPs) in muscles specific to the observed or imagined action. This study aimed to determine whether MEP amplitude was related to the motor imagery ability of participants. Participants were 15 healt...
متن کاملInfluence of somatosensory input on corticospinal excitability during motor imagery.
Our previous studies showed that corticospinal excitability during imagery of squeezing a foam ball was enhanced by somatosensory input generated by passively holding the ball. In the present study, using the same experimental model, we investigated whether corticospinal excitability was influenced by holding the object with the hand opposite to the imagined hand. Corticospinal excitability was...
متن کاملThe effect of somatosensory input on motor imagery depends upon motor imagery capability
We investigated that the relationship between motor imagery ability and the effect of tactile input associated with holding a tennis racket on motor imagery of the forehand and backhand swings. The effect was assessed by the time utilized for motor imagery (mental chronometry). Seventeen tennis players imagined forehand and backhand swings with a forehand grip, a backhand grip or while holding ...
متن کاملIncreased motor cortex excitability during motor imagery in brain-computer interface trained subjects
BACKGROUND Motor imagery (MI) is the mental performance of movement without muscle activity. It is generally accepted that MI and motor performance have similar physiological mechanisms. PURPOSE To investigate the activity and excitability of cortical motor areas during MI in subjects who were previously trained with an MI-based brain-computer interface (BCI). SUBJECTS AND METHODS Eleven he...
