Several studies highlighted the involvement of the motor system during language comprehension (Pulvermüller & Fadiga, 2010). Indeed, studies performed in neuroimaging showed in healthy subject an implication of the primary motor cortex and the premotor cortex during action verbs processing (e.g., Boulenger et al., 2006) and in patients with motor lesions a selective deficit in action verbs processing (Boulenger, et al., 2008). Furthermore, cerebral motor regions involvement seems to be related with the effector involved in the verbs (e.g., hand for clap, see Hauk et al., 2004) and also manual laterality involved in these verbs (Hauk & Pullvermüller, 2011). These and others observations support the hypothesis suggesting a functional contribution of the motor system during language comprehension. Nevertheless, the presence of a bidirectionality in their interaction is currently unclear (see Yang & Shu, 2012). Moreover, recent studies showed that the involvement of the motor cortex is not only restricted to the access of the language information but also involved in the access of the conceptual knowledge. Thus INTERLAM aims to understand the bidirectionality of the language and motor systems interaction during concept access with a multidisciplinary approach. From a fundamental point of view INTERLAM allows us to better understand the necessary and sufficient information to facilitate access to the conceptual representation. From an applied and clinical point of view INTERLAM could help to promote new rehabilitation methods based on training preserved abilities. Specifically, we plan, use these knowledge to propose rehabilitation programs for language disorders by training the motor system (see Arévalo et al., 2012 Karbach & Schubert, 2013). Finally, this theoretical knowledge could also benefit in the construction of new learning methods for several developmental learning disorder (such as dyslexia and dyspraxia).
