Working memory (WM) is the means by which a limited amount of information is actively maintained and processed for a short period of time (Sala et al, 2003). Attention orienting is strongly dependent on WM (Lepsien et al, 2006). WM is also important for Mental Imagery (Mellet et al, 1998) associated with text understanding. Here we assume that FM1 is associated with WM and the Executive Control of Attention required to pay attention to the text being listened and to understand it, that is to extract its meaning. Meaning extraction is supposed to involve mental imagery.
Lef frontal and temporal cortex are the neural correlates of language processing (e.g. Perani et al, 1999). Here, we assume that FM2 is associated with this language processing.
Mental Imagery required to the text understanding is a very complex process that may include different networks (Mellet et al, 1998) and it is attained by recruinting posterior associative areas (Thompson-Schil et al, 2005; Wallentin et al, 2006). Here, we assume that FM3 is correlated with the action of these posterior areas associated with the text understanding.
