103. Donovan had a stroke last year, and doctors were unsure whether or not he would ever fully recover.  Donovan did very little physical exercise to help speed up his recovery, but the damaged cells in his nervous system still managed to regenerate and reestablish their network connections.

105. Which of the following developmental changes in the brain occurs after birth? 
A. The number of dendrites and synapses increases until adolescence, when they are reduced.
B. The number of axons increases and the number of dendrites decreases throughout adolescence and adulthood.
C. No developmental changes occur after birth because all the neurons the brain will ever have are present at birth.
D. New neurons grow until adolescence, when they begin to die.

106. At which of the following ages will you show the greatest number of dendrites in neurons of your cerebral cortex?

D. Gases

109. Donald is seventy years old. For the past few years, he has developed a memory loss that is getting worse, and his personality has become very erratic. His doctors say he has Alzheimer’s disease, but you aren’t sure. What finding should most convince you that the doctors are right?
