Functional heterogeneity in the left lateral posterior parietal cortex during visual and haptic crossmodal dot-surface matching.

Taken together, the findings suggest that functional heterogeneity of the left LPPC during visuo-haptic crossmodal dot-surface retrieval processing reflects that the left LPPC does not simply contribute to retrieval of past information; rather, each subregion has a specific functional role in resolving different task requirements.
