13 You are a neurologist in a large hospital. The wife of a construction worker visits you and describes that her husband has experienced a serious injury to his frontal lobe. She is perplexed by his behavior. Which of the following would you tell her is “ normal behavior ” for a person with frontal lobe damage? A. not much decline in memory or intelligence B. poor judgment C. irritability and other personality changes D. ALL of these are commonly seen in frontal lobe damage

15 As Allison reaches for a box in her garage, out jumps a big spider. Her heart immediately begins to race as she withdraws her hand, but soon she realizes that the spider is harmless, and she begins to calm down. Which part of her nervous system is responsible for brining her back to a normal state of arousal? A. sympathetic nervous system B. somatic nervous system C. parasympathetic nervous system D. skeletal nervous system

33 Discussion Question

34 Your best friends invite you over for pizza and a friendly game of cards. Describe how the following parts of the brain are involved during your evening of eating pizza, socializing, and playing cards: Broca’s area, hippocampus, hypothalamus, and occipital lobe.

35 Broca’s area? Hippocampus? Hypothalamus? Occipital lobe?

36 Broca’s area is involved with socializing and helps everyone talk to one another. The hippocampus is involved with socializing and helps everyone form immediate and long-term memories of the evening. The hypothalamus is involved with eating pizza and lets everyone know if they are hungry or full. The occipital lobe is involved with all aspects because it helps everyone to see the cards, the pizza, and each other.
