Module 6: The Brain Exam Questions
With Complete Solutions Graded A+
case study - ANSWER-A research technique in which one person is studied in depth in
the hope of revealing universal principles
computed axial tomography (CAT or CT) - ANSWER-a series of x-ray photographs
taken from different angles and combined by computer into a composite representation
of a slice through the body
magnetic resonance imaging (MRI) and functional magnetic resonance imaging (fMRI) -
ANSWER-Techniques using magnetic fields and radio waves to produce computer-
generated images of the brain (fMRI shows brain activity, including blood flow)
Electroencephalogram (EEG) - ANSWER-An amplified recording of the waves of
electrical activity that sweep across the brain's surface. These waves are measured by
electrodes placed on the scalp.
Positron Emission Tomography (PET) - ANSWER-a visual display of brain activity that
detects where a radioactive form of glucose goes while the brain performs a given task
brainstem - ANSWER-the oldest part and central core of the brain, beginning where the
spinal cord swells as it enters the skull; it is responsible for automatic survival functions
medulla - ANSWER-located at the base of the brainstem, it controls basic life-support
functions like heartbeat and breathing
reticular formation - ANSWER-a nerve network in the brainstem that plays an important
role in controlling wakefulness and arousal
