Title The effect of visual and auditory enhancements on excitability of theprimary motor cortex during motor imagery

چکیده
22 The effect of visual (VIS) and auditory (AUD) enhancement of finger movement on corticospinal 23 excitability during motor imagery (MI) was investigated using transcranial magnetic stimulation 24 (TMS) technique. Motor evoked potentials (MEPs) were elicited from the abductor digit minimi 25 muscle during MI with information of AUD, VIS, AUD and VIS (AUD+VIS), and no information 26 (NI). Ten healthy subjects were instructed to imagine repetitive abduction and adduction of the fifth 27 finger. After each condition, the extent of vividness of MI was rated using a visual analogue scale 28 (VAS). The results showed that mean VAS score and MEP amplitude for the AUD+VIS condition 29 were higher than those of other conditions, indicating enhanced excitability of the primary motor 30 cortex with a clearer image of motor action during MI.

Visual cortex excitability increases during visual mental imagery--a TMS study in healthy human subjects.
Previous neuroimaging studies provided evidence that visual mental imagery relies, in part, on the primary visual cortex. We hypothesized that, analogous to the finding that motor imagery increases the excitability of motor cortex, visual imagery should increase visual cortex excitability, as indexed by a decrease in the phosphene threshold (PT). In order to test visual cortex excitability, the...

There is increasing interest in electroencephalogram (EEG)-based brain-computer interface (BCI) as a tool for rehabilitation of upper limb motor functions in hemiplegic stroke patients. This type of BCI often exploits mu and beta oscillations in EEG recorded over the sensorimotor areas, and their event-related desynchronization (ERD) following motor imagery is believed to represent increased se...

متن کاملInfluence of imagined posture and imagery modality on corticospinal excitability.
Single pulse transcranial magnetic stimulation (TMS) was used to test the assumption that kinesthetic imagery of action is more 'motor' than visual imagery of action. We assessed corticospinal excitability during motor imagery of a thumb-palm opposition movement by recording potentials evoked by TMS from two hand muscles that would (opponens pollicis, OP, target) or would not (abductor digiti m...
متن کاملCorticospinal excitability is specifically modulated by motor imagery: a magnetic stimulation study.
Transcranial magnetic stimulation (TMS) was used to investigate whether the excitability of the corticospinal system is selectively affected by motor imagery. To this purpose, we performed two experiments. In the first one we recorded motor evoked potentials from right hand and arm muscles during mental simulation of flexion/extension movements of both distal and proximal joints. In the second ...
