Problem
Sean is a 19 year old college student who was involved in a head-on collision with another vehicle on "the stretch" leading to Alcorn State University. He is transported to Natchez General Hospital with suspected head trauma and traumatic brain injury. There, he complains of several symptoms including visual disturbance. Upon examination of Sean's vision, it is apparent that he is exhibiting left side neglect (not responding to stimuli and ques from the left side of his body.) What structure might be affected that is leading to Sean's left sided neglect?
