Case Study
A research technique in which one person is studied in depth in the hope of revealing universal principles
Computerized Axial Tomography (CT or CAT)
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)
A technique that sues magnetic fields and radio waves to produce computer-generated images that distinguish among types of soft tissue;
this allows us to see structures within the brain
Electroencephalogram (EEG)
An amplified recording of the waves of electrical activity that sweep across the brain's surface
Positron Emission Tomography Scan (PET Scan)
A visual display of brain activity
Brainstem
The oldest part and central core of the brain, responsible for automatic survival functions.
Medulla
Located at the base of the brainstem. It controls basic life-supporting functions like heartbeat and breathing
Reticular Formation
A nerve network in the brainstem that plays an important role in controlling wakefulness and arousal
Thalamus
The brain's sensory switchboard, located on top of the brainstem; it directs messages to the sensory receiving areas in the cortex
Cerebellum
The "little brain", attached to the rear of the brainstem; it helps coordinate voluntary movements and balance
Limbic System
A ring of structures at the border of the brainstem and cerebral cortex; it helps regulate functions such as memory, fear, aggression, hunger, and thirst
Hypothalamus
A neural structure lying below the thalamus;
it helps regulates the body's maintenance activities, such as eating, drinking, body temperature, and it linked to emotion
Hippocampus
A neural center located in the limbic system that wraps around the back of the thalamus; it helps process new memories for permanent storage
Amygdala
An almond shaped neural cluster in the limbic system that controls emotional responses such as fear and anger
Cerebral Cortex
The intricate fabric of interconnected neurons that form the body's ultimate control and information processing center
