Figure 5.

The proposed covert verb generation model based on group ICA maps shown in Figure 1. This model is based on our previous publication (Karunanayaka et al., 2010; Figure 4). The brain cartoon shows the approximate locations of each IC map from Figure 1. Transparent ellipses indicate regions located medially within the brain and not visible from the lateral surface whereas opaque ellipses correspond to regions that are mainly located on the lateral surface of the brain. IC d is represented in both frontal and temporal–parietal regions as reflected in the distributed nature of this left-lateralized network. The network is divided into word processing (shown in blue) and word generation modules (shown in green). The SEM block diagram at bottom shows how these brain networks are graphically connected forming the basis for the cognitive model for the covert verb generation task. Only the Feed Forward Connections are evaluated.
