What is a Neurotransmitter? - Definition, Types, Function & Examples

3. 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.

Nervous System Overview: Central & Peripheral

4. Nervous System Overview: Central & Peripheral

What happens in your nervous system when you react to stimuli? Did you know that the brain is sometimes uninvolved with reflexes? Find out the answer to these questions, and more, in this lesson on the human nervous system.

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.

What is Neuroplasticity? - Definition & Examples

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.

Techniques to Study the Brain and Behavior

7. 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.

Endocrine System Function & Hormone Regulation

8. 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!

What Is a Gene? - Definition & Structure

9. What Is a Gene? - Definition & Structure

Genes are little codes found in our cells that make up who we are. This lesson covers where genes are located, how we get our genes, and the functions of genes.

How Genetics and the Environment Interact in Human Development

10. How Genetics and the Environment Interact in Human Development

Everyone is different. But what makes a person unique? In this lesson, we'll examine the way genes and the environment affect who a person is, including looking at the nature vs. nurture debate and looking at how nature and nurture influence one another.

Twin and Adoption Studies: Practices & Findings

11. Twin and Adoption Studies: Practices & Findings

What is more influential, nature or nurture? How can scientists know for sure? In this lesson, we'll look at studies designed to separate the effects of genetics and environment on people's behavior, twin and adoption studies.
