Lesson Plan—Brain Imaging
Summary
During this 60 minute lesson, students will learn about MRI techniques and demonstrate an understanding
of brain anatomy and function. Students will have learned about the lobes of the brain and neuron function
in the previous lesson.
Key
•
•
•
Concepts
Location of lobes of the brain
Functions of each brain lobe
Understanding of the use of MRI techniques
Objectives
• Observe and locate lobes of the brain from MRI images
• Demonstrate understanding of brain lobe functions
• Synthesize opinions of future neuroscience applications
Materials
• Brain Imaging Worksheet
•
MRI images
•
Mind Reading Video
Procedure
1. Explanation of fMRI and MRI techniques and purposes: Teacher and students will discuss what fMRI is,
how it works and why it is useful. (10-15 minutes)
2. Brain Imaging Station Activity: Students will be broken up into groups of 2. They will then visit one of
four stations. At each station they will obtain an image of a “particular patient’s” MRI scan. The students
will have to use the scan to “diagnose” what part of the brain is damaged, what area is affected and what
functions might be involved. Students will be able to look at their textbooks for research. (20-25
minutes)
3. Discussion of Brain Imaging Station Activity answers: Student volunteers will take turns diagnosing a
patient in front of the class and explaining their reasoning. (10 minutes)
4. Mind Reading video and discussion: Students will watch the 60 Minutes Video “Mind Reading” and will
then discuss opinions of video and the future of neuroscience as a class. (20 minutes)

Assessment
• Using the MRI station activity, students will identify regions of the brain that are damaged. They will
also need to list possible functions that will be affected by these damaged areas. They will graded on
their answers.
• General understanding will also be assessed orally by asking questions and discussing opinions of the
video.

4.4 Explain how the nervous system (brain, spinal cord, sensory neurons, motor neurons) mediates communication
among different parts of the body and mediates the body’s interactions with the environment. Identify the basic
unit of the nervous system, the neuron, and explain generally how it works.
