Discussion Question
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.
•
•
•
•
Broca’s area?
Hippocampus?
Hypothalamus?
Occipital lobe?
• 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.
