Textbook Question
Chapter 43, Problem 10TYPSS
Alzheimer’s disease is a common form of dementia affecting millions of people, especially the elderly. Two regions of the brain are particularly affected, often shrinking dramatically and accumulating large deposits of extracellular material. Based on your knowledge of memory, what two brain regions do you think these are? Explain.

Epilepsy is a neurological disorder that disrupts neural activities and causes recurrent seizures. About 70% of people with epilepsy can be treated with medication to prevent seizures from occurring. If medication does not work, surgery is an option for some patients. One of the procedures involves cutting the brain so that the seizures cannot be spread to other parts of the brain.
A common goal of the surgical procedure to treat epileptic seizures is to reduce the connection between the two hemispheres of the brain. By cutting through this structure, an epileptic seizure occurring on one side of the brain will not be spread to the other side.
Identify the structure that connects the two hemispheres of the brain.
In PET scans, red areas are brain regions that are most active, while blue, yellow, and green areas are least active. Figure 13.24 shows PET scans of normal brain activity (left) and (right) of the brain of a person while using cocaine. The frontal lobes of the brain hemispheres are toward the top of the scans. Their neurons play major roles in reasoning and other intellectual functions. Looking at these scan images, how do you suppose cocaine may affect mental functioning?
Leonard in Memento (2000) has total anterograde memory loss but no loss of retrograde memory (he can even remember sustaining the injury). Discuss: a) What he can and can't do well cognitively? b) What Hollywood got wrong about amnesia or memory?
