Textbook Question
Chapter 13, Problem 2CRCAQ
When Ralph had brain surgery to remove a small intracranial hematoma (blood mass), the operation was done under local anesthesia because he was allergic to general anesthetic agents. The surgeon removed a small part of the skull, and Ralph remained conscious. The operation went well, and when Ralph asked the surgeon to stimulate his (unharmed) postcentral gyrus mildly with an electrode, the surgeon did so. Indicate which of the following happened, and explain why: (a) Ralph was seized with uncontrollable rage. (b) He saw things that were not there. (c) He asked to see what was touching his hand, but nothing was. (d) He started to kick. (e) He heard his mother's voice from 30 years ago.

Peyton felt strange when she awoke one morning. She could not hold a pen in her right hand when trying to write an entry in her diary, and her muscles were noticeably weaker on the right side of her body. Additionally, her husband noticed that she was slurring her speech, so he took her to the emergency room. What does the ER physician suspect has occurred? Where in the brain might the physician suspect that abnormal activity or perhaps a lesion is located, and why?
A 40 year old male has just been diagnosed with amyotrophic lateral sclerosis, better known as Lou Gehrig’s Disease. A recent MRI has shown significant demyelination of the gracile nucleus of the dorsal columnar-medial lemniscal pathway. Describe the physiology of this pathway and discuss what neurological deficits this patient will experience due to his lesion.
