NEUROSCIENCE: BRAIN AND BEHAVIOR
The Impact of Stress on Body and Mind
How does stress affect the body, brain and behavior? What are the current stressors in your life? How can we better manage stress? View the Power Point presentation below. Note: You need Power Point software on your computer to view. Also visit other related links on stress listed below. Then go to Web Board to post your response.

Anger and Its Impact on the Brain and Body and How To Manage It
How does anger have an effect on the body? What are the psychological and physiological effects? What does the current research say about anger? Does anger kill? Why? What are ways we can manage anger?

This excellent web site provides a variety of online multimedia activities related to neurobiology. Visit the site by clicking on the hyperlink on the title above. When you get to the site, on the home page in the left frame, click on, "Explore." Go to the section on Neurons (and if you have time, explore the entire site.) Check out the virtual tour of the nervous system. Tour a gallery of photographs of nerve cells. Compare the brains of different animal species. Travel through time and review the history of brain science.
Prepare answers to the following questions:
1. How many neurons are there in the average human brain? What features do neurons have in common
with other cells in the body? In what ways are neurons unique? What's inside a neuron?
2. Did you know that neurons are the oldest cells in your body? Unlike other body cells, which routinely die and are replaced, neural cells are not replaced when they die. This means that you have fewer neurons as you get older, but the ones you have are the very same ones you were born with! Why do you think this is so? In other words, what evolutionary advantage does this "quirk" of neurons convey to our species?
3. The axons of neurons differ in the speed with which they conduct neural impulses. How many different basic neural speeds are there? Is there a relationship between the type of information conveyed by an axon and the speed at which it conducts?
4. What defensive weapon do spiders, snakes, scorpions, and some bees share in common? List three of
these weapons and explain the effect of each on the neurons of a predator. How are these substances similar to nerve agents and other chemical weapons?
5. Why are glial cells referred to as the "forgotten brain cells?" State five ways that glia differ from neurons.
What would happen to your behavior if your glia suddenly stopped functioning?

Prepare answers to the following questions:
1. What differences in the brains of women and men have been found in research studies using MRI and NMR?
Are differences in people's cognitive abilities (for example, memory) related more to individual differences or to whether they are male or female?
2. Is it true that people only use 10 percent of their total brain capacity? How did this fact (or falsehood) originate?
3. September 13, 1998, was the anniversary of what important event in the history of brain science?
4. What ever became of Albert Einstein's brain? Did Einstein's brain differ physically from the average human brain?
5. Throughout history, people have compared the brain to different inventions, such as the telephone. What is the
current metaphor for the brain? In what ways does this metaphor hold up? In what ways does it fail?
(Hint: State the similarities and differences between the brain and this invention.)
Mastering Brain Structure and Functioning
Review your textbook and some of the web sites under related links on the structure and functions of the various parts of the brain. Come to class prepared to report on the following question, indicating function and reaction: How might each of the following parts of the brain be active while you drive a car? While you drive a car experiencing stress from sitting in traffic? While you are displaying road rage?
Limbic System (as a whole)
Three Case Studies on Brain Activation
In each case described below, indicate the parts of the brain activated in the situation.
Anne, the landscape artist, is standing at her easel, painting with her right hand as she looks out the window at her garden. She's listening to classical music as she paints.
Crazy Eddie, the professional wrestler, is in the ring wrestling. The crowd is yelling and his opponent is taunting him. Eddie yells back at his opponent. The two of them are out of breath and sweating profusely. They continue their well-orchestrated series of wrestling moves.
Jill is a law student studying for her exam. She is reading about violent rape and murder cases. She is snacking on popcorn and drinking coffee.
The Endocrine System
Visit the links below on the endocrine system, and along with your textbook, answer the following questions:
1. What is Endocrinology?
2. What are the functions of the each endocrine gland: hypothalamus, pituitary, thryoid and parathyroid,
adrenal, gonads, and others? List the hormones produced by each. List some of the disorders that can
occur with excesses and deficiencies of each gland.
This is the largest web site for understanding the endocrine system and its disorders. It includes an introduction to endocrinology and endocrine surgery. Discusses the hormones produced by the endocrine system and discusses each endocrine gland. Begin with the introduction and then move through each link discussing each endocrine gland. An excellent site!
This site is a comprehensive overview of the endocrine system, including the fundamental concepts in endocrinology, with a definition. The site will provide you with a tour of the endocrine system.
