The task required volunteers to solve a charade by first listening or reading a sentece and then selecting a figure associated with the phrase's meaning. This required decoded verbal information to be hold in verbal WM in the left hemisphere in order to guide the recall of the visual memory required to solve the charade (e.g. Cabeza et al, 2000). We assume that FM1 pictures these WM activities. In the case of listening, these activities predominated in the left hemisphere whereas in the case of reading they predominated over the righ hemisphere.
The charade's verbal decoding is supported by the activity ofthe lef frontal and temporal cortices (e.g., Perani et al, 1999, Kuperberg et al, 2000, 2006; Xu et al, 2005). Also, the Broca´s areas, the temporal and occipital cortices are involved in face and scene processing (Lundstrom et al, 2005; Nakamjura et al, 2000; Wallentin et al, 2006). We assumed that FM2 is associated with these activities. In the case of listening, such a decoding envolved also a bilateral occiptal activity.
Both the right and temporal and parietal lobes are involved in semantically integrating verbal and visual information (e.g., Nakamura et al, 2000; St George et al, 1999; Wallentin et al, 2006). Here we assume that FM3 is associated with the posterior left/right semantic integration.
