About This Chapter
Biology in Psychology - Chapter Summary and Learning Objectives
Although we tend to think of our minds as separate from our bodies, there are many biological functions that affect our psyches in different ways. In this chapter, you'll learn about the brain's structure and how it receives chemical and electrical signals via neurons and neurotransmitters. You'll also learn about our complex system of glands, which secrete hormones that affect our mood and temperament. The nature versus nurture debate is one of the biggest questions scientists have asked, and we'll look at how genetics play a role in the formation of personality and behavior. This chapter is designed to teach you:
- The physical structures that form our nervous and endocrine systems
- How genetics can affect human behavior
- The types of scans researchers use in studying physiological connections
- The unique functions and abilities of brain tissue
|Physiological Techniques||Learn about techniques like CAT scans, MRIs, fMRIs, and PET scans and how these help researchers find links between the brain and behavior.|
|Intro to Biological Psychology||Explore the biological processes that can affect our mental states, moods, and behaviors.|
|Neurons||Understand the structure and function of nerve cells in your brain, muscles, and glands.|
|Neurotransmitters||Learn how the chemical signals fired by neurons tell your body and mind what to do.|
|Parts of the Brain||Explore the various parts of our brain and learn what each part does.|
|Neuroplasticity||Understand the brain's ability to change and adapt to damage and why this is a useful function.|
|Endocrine System||Learn about the body's glands and hormones and how these affect body functions and behavior.|
|Genetics and Behavior||Explore the role of genetics in human behavior and what may be inherited versus what is environmental.|
1. Intro to Biological Psychology
What are the biological factors that affect our behavior? In this lesson, you'll take a look at biological psychology, which looks at the interplay between biological processes and mental states.
2. Techniques to Study the Brain and Behavior
Why do you behave the way you do? Human behavior begins in the brain. To study the brain, psychologists use a variety of tools, like EEG, PET and CAT scans, MRI, DTI, and studying pathology in individuals.
3. What is a Neuron? - Definition, Parts & Function
What are the parts of a neuron? You'll watch Neuron Garciaparra work up a sweat as he throws baseballs to demonstrate the structures and functions of the billions of neurons that reside in your body.
4. What is a Neurotransmitter? - Definition, Types, Function & Examples
How do our bodies communicate with our brains and vice versa? In this video, you'll see how neurons and neurotransmitters can be likened to billions of tiny baseball players engaged in a non-stop game of catch.
5. Parts of the Brain
Is there a way to easily remember the many parts of the brain? Don't be afraid of all these complex terms; this lesson outlines some easy and fun phrases to help you memorize the brain's anatomy. Let's take a look.
6. What is Neuroplasticity? - Definition & Examples
Is your brain preprogrammed and unchangeable or adaptive and malleable? As you watch this video, you'll explore how the brain, a more resilient and resourceful machine than any computer, responds to damage and new experiences.
7. Endocrine System Function & Hormone Regulation
Our hormones play a big part in how we feel and behave throughout the day. Hormones also affect important bodily functions. What other functions do our hormones regulate? Find out in this lesson on the endocrine system!
8. Biological Influences on Human Behavior: Genetics & Environment
Humans are a product of both our genetic makeup and our environmental surroundings. Does one influence our behavior more than the other? It can be difficult to tell, but there are ways that scientists can better understand why we do the things we do.
