“…In the context of the principle of functional equivalence and the simulation theory (Jeannerod, 2001, 2004, 2006), the study of action representation from a neurophysiological point of view has received tremendous research interest (for overviews, see e.g., Decety, 2002; Guillot et al, 2014). While considerable research attention has been directed to comparing the different states of action, such as the imagery and the execution of an action (e.g., Decety, 1996, 2002; Jeannerod and Frak, 1999), only few studies exist that compare learning by way of imagery and execution and respective changes in the brain (e.g., Pascual-Leone et al, 1995; Jackson et al, 2003; Nyberg et al, 2006; Zhang et al, 2012, 2014; Allami et al, 2014; Avanzino et al, 2015; for a review, see Di Rienzo et al, 2016). …”
