Lesson 3: The Brain-Before you begin!
Homework Name
Period
Answer the questions below, and be prepared to share with your peers tomorrow.
1. A drug binds to receptors in the hippocampus. We might expect which of the following symptoms in a user of this drug?
Indicate ALL that are correct based ONLY on this information.
Exhaustion
Forgetfulness
Irritability
Nausea
Relief from pain
Hallucination
2. What did Phineas Gage tell us about brain organization?
3. Adenosine is a brain chemical that makes feel sleepy and which inhibits the reticular pathway. Based on this, which is
true about how caffeine works.
Caffeine is an adenosine agonist that stimulates the reticular pathway
Caffeine is an adenosine agonist that inhibits the reticular pathway
Caffeine binds outside the reticular pathway and stimulates adenosine release
Caffeine is an adenosine antagonist that inhibits the reticular pathway
Caffeine is an adenosine antagonist that stimulates the reticular pathway
4. Where is gray matter relative to white matter?
Gray matter is found in the cerebellum while white matter is found in the cerebrum
Gray matter is found in the cerebrum while white matter is found in the cerebellum
Gray matter is found on the outside of both cerebrum and cerebellum, white matter is on the inside
White and gray matter are sprinkled about randomly in the brain
Gray matter is in the spinal cord and white matter only in the brain

Guiding Questions
1.
Which brain regions are important for particular functions?
2.
3.
4.
How do we know about the relationship between brain structure and functions?
How is the brain organized?
How do brain regions integrate with others to enable different functions?
Key Terms: Some will be duplicated in the pre-lab for the brain dissection

In Lecture:
Some activities will be covered in supplemental work (Activities 2-3), supported by lecture. Activities 5-9 review
different pathways in the brain. It is advisable to review these sections on Edmodo before lecture, as we will go
through them fairly quickly. Please record responses to in-class questions on this sheet.
