Figure 1.

Tractographic reconstructions of masticatory muscular complex. (a, b) Sagittal and frontal view of the masticatory muscular complex with a directional color coding representation, overimposed on a T₁ weighted image (the mandible is reconstructed as a white volume). (c) Frontal view of the masticatory muscular complex with a local index of FA color coding representation overimposed on a T₁ weighted image (lateral scale represents FA values from 0 to 1). (d–f) Volume rendering of the upper portion of the head of the patient with tractographic reconstructions of masticatory muscular complex (axial and coronal T₁ weighted images are underlaid). Arbitrary colors were given to fibers: masseter muscles are represented in red, lateral pterygoid muscles are represented in yellow and medial pterygoid muscles are represented in blue.
