Dr. snell studies the part of the brain that is active when people are lying. she asks half of her participants to tell the truth about an event from their childhoods and half to tell a lie about an event from their childhoods. she will then use to detect brain areas that are active when the participants are lying.

Brain Imaging Techniques

Explanation: 1- Brain Imaging Techniques, also know as Neuroimaging or Brain-Scanning, are techniques used to image the brain and it serves multiple purposes.

2- In this particular case, Dr. Snell wants to do a functional imaging, which is one of the two broad categories of neuroimaging.

3- Functional Imaging allow doctors to see the brain while is functioning and brain information processing can be visualized directly because the areas that are functioning in any type of mental state "Lights up" on the scan.

4- In this case, Dr. Snell will use Brain Imaging Techniques, in order to detect brain areas that are active when the participants are lying.
