About This Document

This assignment covers various topics in neuroscience such as levers, breathing, neurotransmitters, spinal cord anatomy, brain injury, autonomic nervous system, memory, equilibrium, hormones, and enuresis. It includes questions on the three categories of levers, muscles used in breathing, drugs that modify neurotransmitter effects, spinal reflex arc, brain injury case study, effects of anticholinergic medication, sympathetic and parasympathetic divisions, reticular activating system, short-term and long-term memory, smell sensation, equilibrium, lipid-soluble and water-soluble hormones, and vasopressin for enuresis.

(3 marks)5.In 1848, a railroad worker named Phineas Gage was seriously injured during an explosion on the job. A tapered metal rod ranging from 0.25 inches to 1.25 inches in diameter and over 3 feet long entered his skull just under his left cheek bone and exited through the top of his skull. The rod was found over twenty feet away. Amazingly, Gage lived even though he suffered massive damage to the left front ofhis brain. His personality and intellectual abilities changed, however. Before the accident, he was respected as a smart, capable and even-tempered man. After theaccident, he was foul-mouthed and bad-tempered and could not make up his mind. In the years immediately preceding his death, he began to have epileptic seizures. Explain the changes observed in Mr. Gage based on your knowledge of the brain. (4 marks)
