Module 5 Flashcards
What is a case study
1 person studied in depth (usually done with brain accidents)
-No one can ethically do experiments on the brain
Brain scans are divided into how many categories
2: Brain structure and Brain Function
What two scans studies brain structure
Computerized axial tomography (CT or CAT)- takes x-rays of different angles
Magnetic resonance imaging (MRI)- uses magnetic fields and radio waves to distinguish different soft tissue. (can find tumors or locate brain damage)
What two scans studies brain function
Electroencephalogram (EEG)- an amplified recording of waves of electrical activity. (sleep disorders/seizures)
Positron emission tomography (PET)- injection of radioactive glucose to detect where it goes in the brain when performing a specific task.
What is the Brainstem
Central core of the brain
What is the Medulla
Controls heartbeat, breathing, circulation, and swallowing
-located at the bottom of the brainstem
What is the Reticular Formation
Nerve Network that helps control wakefulness
What is the Thalamus
It directs messages for processing
-it’s at the top of the brainstem
-The sensory switchboard
What is the Cerebellum
Controls voluntary movements and balance
Plays a role in governing emotions, hearing, and balance
-“little brain”
Controls memory on how to use your body like walking and dancing
What is the Limbic System
Regulates functions like fear, memory, aggression, hunger, and thirst
How many structures is the Limbic System made up of
3: Hypothalamus, Hippocampus, and the Amygdala
What is the Hypothalamus
Regulates maintenance functions
-hunger, thirst, reaction to stress, and body temp.
What is the Hippocampus
Helps process new memories for permanent storage
What is the Amygdala
Controls many emotional responses especially fear and anger
What is the Cerebral Cortex
The wrinkled outer surface that covers your brain
-made up of interconnected neurons that make up the body’s ultimate control of info processing
