How the Brain & Cognition Change with Age

1. 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

2. 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

3. 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

4. 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.

The Benefits of Exercise on the Developing Brain

5. 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

6. 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.

How Age Affects Our Neurons: Major Changes & Their Effects

7. 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

8. 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.
