Chapter 1: What is the main topic discussed in this episode?
And now for another Human Factors Minute.
Chapter 2: What is an electroencephalogram (EEG) and how does it work?
An electroencephalogram, or EEG, is a test that detects abnormalities in your brain waves, or in the electrical activity of your brain. The device works by placing electrodes consisting of small metal discs with thin wires are pasted onto a participant's scalp. The electrodes detect tiny electrical charges that result from the activity in brain cells.
The charges are amplified and appear as a graph on a computer screen, or as a recording that may be printed out on paper.
Chapter 3: How are EEGs used in Human Factors research?
In human factors, EEGs are used typically to measure performance with respect to mental fatigue, mental workload, mental effort, visual fatigue, emotion, and even stress. Many studies in human factors focus on evaluating an individual's mental states while operating a vehicle. However, there are plenty of other practical applications for using an EEG.
Chapter 4: What are the practical applications of EEGs outside of Human Factors?
Outside of human factors, the EEG can be used to evaluate several types of brain disorders, diagnose other disorders that influence brain activity, determine the overall electrical activity of the brain, and to monitor blood flow in the brain during surgical procedures.
Chapter 5: What resources are available for learning more about EEGs and Human Factors?
