The Aging Brain and Nervous System - Chapter Summary
Feel confident that you have a good grasp of how age affects how we feel, think and understand the world around us by reviewing video lessons in this chapter. Each lesson is devoted to a single topic, enabling you to review these concepts at a comfortable pace. When ready, test your knowledge by taking short quizzes and a chapter exam. Any questions you have about the aging brain and nervous system can be sent to our experts. In no time, you will have a good understanding of the following:
- Why cognitive functions and the structure of the brain change with age
- Differences between STAC and HAROLD models of brain activation and aging
- How age-related changes in the dopaminergic system and cognitive aging relate
- What the relationship is between activation patterns in the brain and cognitive functions in older adults
- Why aerobic exercise has a positive impact on brain development
- Similarities and differences between emotional and cognitive processing in older adults
- Ways age impacts neurons and the automatic nervous system
- What neuroplasticity means and how it works
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.
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.
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.
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.
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.
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.
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.
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.
