“…The question remains open whether more practice with motor imagery could also result in the development of motor representation, which has been shown to be effector dependent (Hikosaka et al 1999 ; Park and Shea 2003 ; Verwey and Wright 2004 ). Our results are in accordance with the study performed by Mizuguchi ( 2014 ), showing that activation of brain regions during motor imagery is effector independent. Similar brain activation has been found during motor imagery while imaging an extension and a flexion of right/left hand and right/left foot (Mizuguchi 2014 ), i.e., the left supplementary motor area and inferior frontal gyrus/ventral premotor cortex.…”

Future research needs to clarify whether comparable results can be obtained when learning a motor skill with motor execution and motor imagery with other effectors, i.e., the arms or legs.…”

How effector-specific is the effect of sequence learning by motor execution and motor imagery?

The aim of the present study was twofold. First, we wanted to examine how effector specific the effect of sequence learning by motor execution is, and second, we wanted to compare this effect with learning by motor imagery. We employed a Go/NoGo discrete sequence production task in which in each trial a spatial sequence of five stimuli was presented. After a Go signal the corresponding spatial response sequence had to be executed, while after a NoGo signal, the response sequence had to be mentally imagined. For the training phase, participants were divided into two groups. In the index finger group, participants had to respond (physically or mentally) with the left or right index finger, while in the hand group they had to respond with four fingers of the left or right hand. In a final test phase both execution modes were compared and all trials had to be executed. Response times and the percentage of correct responses were determined to establish learning effects. Results showed that sequence learning effects as assessed in the test phase were independent of the effector used during the training phase. Results revealed the presence of aspecific learning effects in the case of learning a required motor task with an index finger, but sequence-specific learning effects, both due to motor execution and to motor imagery, were not effector specific.Electronic supplementary materialThe online version of this article (doi:10.1007/s00221-017-5096-z) contains supplementary material, which is available to authorized users.

“…In particular, they found that expert athletes showed greater activation than novices in the inferior frontal gyrus and the parietal operculum, when passively listening to familiar sport sounds. Other studies on motor imagery suggest that the inferior frontal gyrus is involved also during mental representation of action [114,115]. Therefore, in the study by Woods and colleagues, the exposition to familiar action-related sounds probably evoked a major representation of action in expert athletes compared to novices, owing to their motor experience.…”

Previous studies have demonstrated that physical therapy accompanied by Rhythmic Auditory Stimulation (RAS) can improve the motor skills of patients with Parkinson’s disease and, in particular, their gait disturbances. In the present work we describe the neurological bases and perceptual-motor deficits generally associated with Parkinson’s disease, with a specific focus on gait disturbances. Within this framework, we review the role of auditory cueing in the modulation of patients’ gait, addressing this issue from the cognitive, neurological and biomechanical perspectives. In particular, we focus on the new frontiers of both assessment and intervention. With regards to the assessment, we describe the advantages of the three-dimensional quantitative multifactorial gait analysis. As concerns the intervention, we illustrate the potential impact of the administration of ecological footstep sounds as rhythmic cues.

“…Though discrepancies have been reported regarding the role of more ventral portions of the PMC (PMCv), a 1995 study demonstrated activation of the PMCv during both MI and motor execution [30]. A 2014 study also confirmed activity in the left PMCv during MI of upper and lower extremities [36]. Additionally, studies on primates have shown that both the PMCd and the PMCv play a key role in the planning, preparation, and execution of motor actions [37].…”

Motor imagery (MI), defined as the mental implementation of an action in the absence of movement or muscle activation, is a rehabilitation technique that offers a means to replace or restore lost motor function in stroke patients when used in conjunction with conventional physiotherapy procedures. This article briefly reviews the concepts and neural correlates of MI in order to promote improved understanding, as well as to enhance the clinical utility of MI-based rehabilitation regimens. We specifically highlight the role of the cerebellum and basal ganglia, premotor, supplementary motor, and prefrontal areas, primary motor cortex, and parietal cortex. Additionally, we examine the recent literature related to MI and its potential as a therapeutic technique in both upper and lower limb stroke rehabilitation.
