From: Chronic itch induced by thalamic deep brain stimulation: a case for a central itch centre
Perspective view of the estimated volume of tissue activated (VTA) in relation to the involved thalamic nuclei (a). Tractography (b) and connectivity study of the left hemisphere (c, d) revealing fibers passing through the VTA with cortical projection to the primary sensory cortex and the posterior cerebral quadrant (light blue area overlaid on normalized T1 MRI scan). VTA (red spheres), ventral posterolateral nucleus anterior (yellow); ventral posterolateral posterior (blue); medial lemniscus (light yellow)
