Parts of the Brain
What is responsible for automatic survival functions; made of the hypothalamus, pons, thalamus, medulla, reticular formation, cerebellum
Brainstem
What are the short fibers that branch out from the cell body and pick up incoming messages?
Dendrites
A regular sequence of biological processes, such as temperature and sleep, occurs every 24 hours.
Circadian Rhythm
The brain and spinal cord
Central nervous system
A technique psychologists use to measure electrical activity in the brain is a(n)
EEG
Rewards center...maintenance activities: eating, drinking, body, and temperature; it governs the endocrine system via the pituitary gland and is linked to emotion
Hypothalamus
Passes messages to its terminal branches.
Axon
A period of sleep lasting about 90 minutes and including one or more stages of NREM sleep, followed by REM sleep.
Sleep Cycle
Connects CNS to the limbs and organs, essentially serving as a communication relay going back and forth between the brain and the extremities.
Peripheral Nervous System (PNS)
To identify which specific brain areas are most active during a particular mental task, researchers would most likely use a(n)
PET scan
Controls heart rate and breathing
Medulla
A layer of tissue that covers the axon and speeds up neural impulses.
Myelin Sheath
A recurring sleep stage during which vivid dreams commonly occur. Also known as paradoxical sleep, because the muscles are relaxed (except for minor twitches) but other body systems are active.
REM Sleep
The division of the PNS controls the body's skeletal muscles. Also known as the skeletal nervous system.
Somatic Nervous System
Areas of the brain that are damaged or removed are referred to as
lesions
Controls one’s balance and voluntary movements
Cerebellum
Pass on chemical messages to other cells and parts of the body
The Axon's Terminal Branches
The relatively slow brain waves of a relaxed, awake state
Alpha Waves
The part of the PNS that controls the glands and the muscles of the internal organs. Controls the sympathetic and parasympathetic nervous systems.
Autonomic Nervous System
Which of the following brain imaging techniques produces the most detailed picture of brain structure?
MRI
A part of the brain that is associated with emotions that drives the body to do certain things
Limbic System
The neuron's support center
Cell body
Recurring problems in falling or staying asleep.
Insomnia
The division of the autonomic nervous system arouses the body, mobilizing its energy in stressful situations.
Sympathetic Nervous System
Which of the following is the structure of the limbic system that plays an essential role in the formation of new memories?
Hippocampus
