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 Take the quiz found at http://faculty.washington.edu/chudler/compare2.html REQUIRED READING From your A&P text. Define all key terms. Brain organization, pg. 260 sections 8.5-8.7 From Internet http://rsabbatini.tripod.com/phineas5.htm http://faculty.washington.edu/chudler/functional.html http://faculty.washington.edu/chudler/sagittal.html http://faculty.washington.edu/chudler/brainsize.html o somatosensory cortex part http://learn.genetics.utah.edu/content/addiction/reward/ o Reward Pathway Reinforces Behavior part 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 Gray matter vs. White matter Cerebrum Cerebellum Brain stem Meninges Thalamus Hypothalamus Hippocampus Corpus Callosum Amygdala Insula Hemisphere PET and MRI scans Limbic Pathway Reticular Pathway Reward Pathway Nucleus accumbens Ventral tegmental area 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.
