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?

03-2-5-4-1 A 04-3-1-2-5 Question 35 Which of the following shows a brain lobe correctly paired with one of its primary functions? O parietal lobe-hearing O temporal lobe-visual processing occipital lobe-control of skeletal muscles O frontal lobe-decision making Question 36 Which of the following must happen for long-term potentiation to occur in the hippocampus? the postsynaptic cell responds to glutamate by opening AMPA receptors

Based on the evidence from recordings of single neurons in the hippocampus and entorhinal cortex in rodents by Nobel Laureates John O'Keefe, May-Brit Moser and Edvard Moser, one would predict that patients like H.M. (whose bilateral medial temporal lobes were removed) would have problems with Short-term memory   Semantic memory   Spatial memory   Object memory   Face memory

A neurosurgeon probes a person’s brain to map its functions. The person is awake and feels no pain during this procedure. As each area of the brain is probed, the person perceives a different sensation, as described in the table. Which structure (or lobe) of the brain is being stimulated in each scenario? [You do not need to explain why. Just state the lobe or structure]  a) “I can hear a radio playing” _____________________  b) “I can see a flash of bright light” _____________________  c) “I can smell the flowers in my garden” ______________________  d) “I remember a happy moment from my childhood” ____________________  e) “I can feel pain in my foot” ____________________  f) “My finger just twitched” ____________________
