101. The 100+-year-olds of the future are more likely to be comfortable because of a. advances in genetics. b. advances in pharmaceuticals. c. improved replacement parts. d. all of these 102. Walking on the six-inch curbs can stimulate which part of the brain? a. amygdala b. hypothalamus c. cerebellum d. hippocampus 103. Which of the following is FALSE regarding the aging brain? a. Brains begin shrinking as early as age 30 and more clearly after the age of 50. b. We actually generate new neurons in the brain well into our 70s. c. The aging of the brain that occurs between 30 and 60 has little effect on how we perform because it does not affect neural processing and we compensate by how we approach tasks. d. Two of the neurotransmitters that decrease are serotonin and lipofuscin. 104. Which of the following is NOT a change that takes place in the brain as we age? a. We experience a large reduction in the number of neurons after age 60 and are unable to generate new ones. b. There is decreased production of the neurotransmitters dopamine and acetylcholine. c. Lipofuscin, a yellowish-brown pigment is deposited as unwanted debris in the neurons in the cerebellum and cerebral cortex. d. The gaps between the folds of the cortex called the sulci widen and the ventricles get bigger. 105. Which of the following is NOT a change that takes place in the brain as we age? a. Neurons shrink as we age because we lose synapses. b. There is decreased production of the neurotransmitters dopamine and acetylcholine. c. Lipofuscin, a yellowish-brown pigment is deposited as unwanted debris in the neurons in the cerebellum and cerebral cortex. d. The gaps between the folds of the cortex called the sulci narrow and the ventricles get smaller. 106. As the brain shrinks, the gaps between the folds of the cortex called the sulci become_______ and the ventricles get ______. a. narrow; smaller. b. narrow; large c. wider; larger. d. wider; smaller. 107. As one ages, there is significant loss of ________, which is the outer layer of cell bodies and ________, which is the layer of myelinated axons that connect various parts of the brain. a. gray matter; white matter b. white matter; gray matter c. the hippocampus; the corpus callosum d. the corpus callosum; the hippocampus 108. Which of the following are the two neurotransmitters that show significantly decreased production in the brain as we age? a. serotonin and lipofuscin b. epinephrine and serotonin c. acetylcholine and dopamine d. lipocfusin and acetylcholine 109. ________ is a yellowish-brown pigment that is deposited as unwanted debris in the neurons of the cerebellum and cerebral cortex as we age. a. Serotonin b. Acetylcholine c. Dopamine d. Lipocfusin 110. Compared to younger adults, older adults a. use more areas of the brain to complete certain tasks. b. use fewer areas of the brain to complete certain tasks. c. use the same number of areas of the brain to complete certain tasks, but complete them significantly slower. d. are unable to use the same brain areas to complete certain tasks because of a massive reduction in lipofusin.
