(FRAME-INFO (STRING "Ventral Posterior Nucleus. \(Image modified with permission from a drawing by C. Kaiser\).  The thalamic ventral posterior nucleus \(VP\) is divided into its lateral \(VPL\) and medial \(VPM\) components. The leg \(white\) and arm \(black\) are represented in VPL and the head \(green\) in VPM. The pain and temperature fibers of the spinothalamic tract are distributed more widely in the posterior thalamus than is shown here. The cortical substrate of pain perception is not well understood. However, recent functional MRI and PET scan studies suggest that the anterior cingulate gyrus and insula cortex may be involved in processing pain information. There is also evidence that pain can be perceived at the thalamic level."))
