DEMOS & CLASSROOM ACTIVITIES--BIOLOGICAL BASES OF BEHAVIOR

I. Topic: Damage to the Brain and its Effects on Behavior

II. Purpose: To aid student understanding of the strong links between brain structure and function and behavior.

III. Description: Handout/Worksheet

This worksheet contains 3 short problems for students to solve. Each problem describes a specific brain injury and its effects on behavior. The student's task is to identify the brain area correlated with the injury and those effects.

Answers to problems: (1) cerebellum; (2) hippocampus; (3) Broca's area (frontal lobe of left hemisphere)

IV. Procedure:

1. Have students work through each problem. When they are finished with all the problems, have students share their answers. Open discussion to the connection between damage to specific brain areas and its effects on subsequent behavior.

Instructions. Below are 3 problems. Each describes a brain injury and its effects on behavior. Your task is to identify the precise area of the brain that has been damaged.
