Learning Curve 2b. Tools of Discovery, Older Brain Systems, and the Limbic System
A(n) _____ scan tracks radioactive glucose to reveal brain activity.
PET
The brain’s _____ helps coordinate movement and enables one type of nonverbal learning.
Cerebellum
When a scientist lesions a brain area, they _____ it.
Destroy
What structure is NOT part of the limbic system?
The Medulla
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.
fMRI
Scientists have discovered in studies with felines that damage to the brain’s _____ results in sleep difficulties.
Pons
Brent is taking part in an experiment in a cognitive neuroscience lab. Silently, he reads rapid sequences of words flashed on a computer screen. The electrical activity of his brain is simultaneously recorded through skull electrodes. The technique used in this study is:
EEG
Shelby was in a car accident and now has problems moving information from her short-term memory into her long-term memory. The _____ in Shelby’s brain was damaged in the car accident.
Hippocampus
Dr. Charles is using _____ when she conducts a series of brain scans by using radio waves to briefly disrupt the brain’s activity.
Functional Magnetic Resonance Imaging (fMRI)
Dr. Garcia is studying prejudice among White Americans using neuroimaging technology. She is particularly interested in which part of the brain is active when those who are prejudiced view photographs of White and Black people. Which neuroimaging technique is Dr. Garcia likely to use?
PET
Tina has trouble sleeping. She wakes up around the same time each night feeling like she cannot breathe. Her physician suspects she may have sleep apnea, a sleep disorder. Which neuroimaging technique is her physician likely to use to determine if Tina has a sleep disorder?
EEG
Colin was always a mild-mannered man. Suddenly his behavior changed radically. He instigated fights and was verbally abusive to the people around him. It is likely that Colin’s problem began in his brain’s _____.
Amygdala
To monitor the electrical activity in the brain that is triggered by hearing one’s own name, researchers would make use of a(n):
EEG
After suffering an accidental brain injury, Kira has difficulty walking in a smooth, coordinated manner. It is likely that she has suffered damage to her _____.
Cerebellum
Dr. Han is studying which brain structure is associated with aggressive behavior among rats. Which part of the brain is she likely to see activated when using neuroimaging techniques?
Amygdala
