Ch 8: The Brain & Nervous System in Older Adults

About This Chapter

Watch engaging video lessons to learn more about the various changes that take place in older adults' brains and nervous systems. These video lessons are short and engaging and make learning easy!

The Brain & Nervous System in Older Adults - Chapter Summary and Learning Objectives

Some changes that take place with aging are obvious even to the untrained eye, while others are more hidden and difficult to detect. In this chapter, instructors will introduce you to the human brain and explain the various types of changes that normally take place as the aging process progresses. You can also learn how moderate use of aerobic exercise may improve the health and functioning of our brains even as we age. After completing this chapter, you should have a better understanding of the topics listed below:

  • How our brains and thinking change with age
  • Effects of age on our autonomic nervous systems
  • Differences between cognitive and emotional processing in aging adults
  • Ways that exercise can be a benefit to our brains

Parts of the Brain

1. 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.

How the Brain & Cognition Change with Age

2. How the Brain & Cognition Change with Age

As brains change over time, there are measurable results that effect a person's cognition. This lesson will explore some of the changes that occur to a person's brain as they age.

HAROLD & STAC Models of Brain Activation & Aging: Definition & Major Differences

3. HAROLD & STAC Models of Brain Activation & Aging: Definition & Major Differences

This lesson explores the HAROLD and STAC models of how the brains of younger people will slowly generalize neural activity from one area to many as they get older.

How Changes in the Dopaminergic System Affect Cognitive Aging

4. How Changes in the Dopaminergic System Affect Cognitive Aging

This lesson examines the changes that occur to the four tracts of the dopaminergic system. We will look at how depredations to each tract lead to a particular type of issue.

Bilateral Activation & Cognitive Functioning: Definition & Overview

5. Bilateral Activation & Cognitive Functioning: Definition & Overview

This lesson looks into what bilateral and unilateral activation is, as well as the machines that allow us to perceive the electrical activity of the brain.

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.

The Benefits of Exercise on the Developing Brain

7. The Benefits of Exercise on the Developing Brain

The brain continues to change as you age and develop. This lesson examines the interaction of exercise with the brain, and subsequent changes to cognition.

Emotional Processing vs. Cognitive Processing in the Aging Adult: Differences & Examples

8. Emotional Processing vs. Cognitive Processing in the Aging Adult: Differences & Examples

This lesson explores some of the changes that occur in people as they age. Specifically, we will look at the interaction between the changes in cognition and the changes in emotional processing.

What is a Neuron? - Definition, Parts & Function

9. 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.

Changes to the Glia with Age

10. Changes to the Glia with Age

Most people have heard of neurons, but did you know that there's another type of brain cell? In this lesson, we'll explore glial cells, what they do, the way they work, what happens to them as we age, and how that can affect us.

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

11. 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.

How Age Affects Our Neurons: Major Changes & Their Effects

12. How Age Affects Our Neurons: Major Changes & Their Effects

This lesson briefly explores the process of aging at a cellular level. The neuron is the most vital component of the brain and follows a particular path when aging.

How Age Affects Our Autonomic Nervous System: Changes & Examples

13. How Age Affects Our Autonomic Nervous System: Changes & Examples

In this lesson, we will look at the autonomic nervous system. We'll focus on areas such as reflex and sensations, expanding our understanding of how these change over time.
