Abstract
Mental imagery is a cognitive function that includes sub-functions such as generation, transformation, and matching. However, the neural substrates for each sub-function are not yet clear. In the present study, we used event-related functional MRI during a modified version of a mental clock task to investigate these neural substrates. While participants were mentally transforming the clock hands, we found activations in the left inferior parietal lobule, left motor related regions (premotor area and supplementary motor area), and left insula, which were contra-lateral to the right hand used to manipulate a 3-D mouse in the learning phase. These results suggest that motor imagery was utilized for transformation of mental imagery.
