Questions for Brave New Brain, Chapter 4 by Nancy C. Andreasen
Read this packet carefully & completely. The reading is very long, complex & detailed. Consider it a primer reading to help you study the brain. As you read feel free to highlight or underline the actual text as needed. These study questions are to help you key in on what is important. Be sure to answer each question fully and completely. I expect you to TYPE the answers. You may find it easier to save a copy from my webpage and fill in the questions as you go instead of retyping the questions. Due to the length of this assignment it will count as a test grade.
(HINT: Questions go in order)
1. What are the three (3) types of brain tissue?
~Gray matter, white matter, and Cerebrospinal fluid (CSF)
2. List the two (2) neurodegenerative disorders that destroy cell bodies.
~Alzheimer’s and Parkinson’s
3. What does the cell body do for the neuron?
~Performs basic command functions
4. Why does “cerebral cortex” mean “bark of the brain”?
~The nerve cell bodies are highly concentrated on the surface of the brain, causing it to look like tree bark
5. What does “subcortical” literally mean?
~Below the cortex
6. Name the two (2) demyelinating diseases listed in the text. What do these types of diseases do?
~Multiple sclerosis (MS) and Amyotrophic lateral sclerosis (ALS) both harm the white matter of the brain and cut the ties that allow the neurons to communicate with one another
7. What are ventricles?
~Parts inside the brain that carry CSF
8. Name two of the three important functions that CSF carries out.
~Contain nutrients and byproducts of brain activity to help the brain
~Replace missing brain tissue
9. What are gyri and sulci? Why do we have them? Draw a diagram to explain.
~Ridges and dips that cover the surface of the human brain in order for the brain to have enough neurons and stay at a healthy size, because the
