Structures of Brain
Four main lobes
Frontal, parietal, temporal, occipital
Function of Motor Cortex
Utilize the recieved information from lobes to carry out body movements
Describe hemispherectomy
Removal of one halves of the brain; used to treat behavioral disorders or illnesses
The cycle of physiological & biological processes that fluctuate on a roughly 24-hour timetable
Circadian Rhythm
Describe Insomnia
Inability to sleep, stay asleep, or get a good quality of sleep
Called "little brain" (hint: underneath occipital lobe)
Cerebellum
Function of Medulla
Controls life sustaining functions (heart rate, breathing, blood pressure)
This provides information about structure or activity of the brain
Brain Scanning
Sleep has a biological rhythm, cycle every 90-110 minutes
Wake/Sleep Cycle
Location & Function of Pons
Brainstem, stimulates breathing & controls sleep cycles
Two cortices (plural of cortex) of the frontal lobe.
Prefrontal & Motor
Function of Somatosensory Cortex
Recieves & processes sensory information from entire body
This machine records brain-wave patterns from the electrical activity from surface of the brain.
Electroencephalograph (EEG)
Amount of stages sleep cycle has & the stage REM happens
5 stages & occurs in 5th stage
Location & Function of Amygdala
Temporal lobe, proccesses emotion & fighting responses
Bundle of nerve fibers that connects the two hemispheres
Corpus Callosum
Difference between Hypothalamus & Hippocampus
Hippocampus: Formation, organization, storage of new memories & connecting emotions to them
Describe CT/CAT scan
2d x-ray photographs from different angles, used to create 3d representation of organ
Chronic medical condition where the affected person repeatedly stops breathing during sleep
Sleep Apnea
This is a brain-imaging method using radio waves & magnetic fields of the body to produce 3d images of the brain
Magnetic Resonance Imaging (MRI Scan)
Locations (lobe & hemisphere) of BOTH Broca's Area & Wernicke's Area
Broca's Area: Frontal lobe, left hemisphere
Wernicke's Area: Temporal lobe, left hemisphere
Difference between Broca's Area & Wernicke's Area
Broca's Area: Determines movements needed for vocalization
Wernicke's Area: Responsible for comprehension of speech
Describe Positron Emission Tomography (PET) scans
Uses trace amounts of short-lived radioactive material to map functional processes in the brain (glucose)
Describe Narcolepsy
Sleep disorder in which a person falls immediately into REM sleep during the day without warning
Functional Plasticity vs. Structural Plasticity
Functional P: Brain's ability to move functions from damaged area to undamaged areas
Structural P: Brain's ability to change its physical structure as a result from learning
