(FRAME-INFO (STRING "Spinoreticular Pathway. \(Spinal cord image modified from N.B. Everett, Functional Neuroanatomy. Lea & Febiger 1971, with permission of Williams & Wilkins\). There are other pathways in the brainstem that may serve as alternate routes for somatosensory information, particularly pain. Most of the anterolateral quadrant fibers terminate in the brainstem reticular formation \(throughout the tegmentum\), including the periaqueductal gray. Only a portion of the anterolateral bundle actually reaches the thalamus directly. Reticulothalamic fibers carry some of the pain information to thalamic nuclei more widespread than the ventral posterior nucleus."))
