“…This is still a controversial issue, however. Bonnet et al [30] found increased spinal reflexes during a mentally simulated isometric foot pressure. Increase was more marked for the limb used for pressing than for the contralateral limb.…”

“…Modulation of F wave amplitude is equivocal [10,41,52,53] while the H reflex tends to be inactive. Although Bonnet et al [3] reported H reflex modulation, the imagery and execution trials were interspersed which may have contributed to the accompanying background EMG activity. Investigations where imagery trials formed a separate block [1] or were no execution trials were performed [27,21] report no change in H reflex amplitude.…”

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 minimi, ADM, control) be activated during actual performance of the very same movement. Participants were asked to imagine the thumb-palm opposition movement while maintaining first person imagery that was either purely visual or predominately kinesthetic. The motor imagery task was performed in two conditions in which the imagined and the actual hand could be either congruent or incongruent. Facilitation of potentials recorded from OP was higher during imagery carried out in mentally congruent than incongruent postures. This effect was largely due to lack of excitability recorded during incongruent kinesthetic imagery, which was indistinguishable from baseline imagery of the static hand. All other conditions differed from static imagery regardless of position. No significant effects were found in a control muscle (ADM) thus indicating that the effect was not related to spatial coding. Subjective reports obtained after the experiment indicate that the results cannot be ascribed to qualitative differences in the imagery experienced. For relatively simple motor tasks requiring no 'expertise' we found no detectable difference in the motor cortex due to imagery modality.

“…Studies revealing the strong relationship between motor simulations and motor system activation, functioning independently of motor performance (Abbruzzese et al, 1999, Bonnet et al, 1997, Decety, 1996, Fadiga et al, 1999, Jeannerod, 1995, Jeannerod, 2001, Porro et al, 1996and Schnitzler et al, 1997 have given rise to the hope that motor imagery will provide a backdoor to the motor system after impairments (Jackson et al, 2001, Lehéricy et al, 2004and Sharma et al, 2006. To this end, motor imagery has been shown in neurofeedback task paradigms to increase regional cortical activation: long-term effects of increased activation of motor areas involving neural circuitries associated with motor skill learning can last up to several days (Kober et al, 2014 andYoo et al, 2008).…”

This study investigates if anodal and cathodal transcranial direct current stimulation (tDCS) of areas above the motor cortex (C3) influences spontaneous motor imagery experienced in the waking resting state. A randomized triple-blinded design was used, combining neurophysiological techniques with tools of quantitative mentation report analysis from cognitive linguistics. The results indicate that while spontaneous motor imagery rarely occurs under sham stimulation, general and athletic motor imagery (classified as athletic disciplines), is induced by anodal tDCS. This insight may have implications beyond basic consciousness research. Motor imagery and corresponding motor cortical activation have been shown to benefit later motor performance. Electrophysiological manipulations of motor imagery could in the long run be used for rehabilitative tDCS protocols benefitting temporarily immobile clinical patients who cannot perform specific motor imagery tasks -such as dementia patients, infants with developmental and motor disorders, and coma patients.
