Midterm 2 Flashcards
Most valued on the lower end
Positive skew
Most values on the higher end
Negative skew
Memory formation/explicit/declarative/episodic memory
Hippocampus
Hunger/thirst/endocrine processes, pituary gland
Hypothalamus
Taste aversion experiment, rats biologically predisposed
Garcia Effect
Extrinsic rewards decrease intrinsic interest in tasks
Overjustification
Neurons stop firing because of constant stimulation
Sensory Adaptation
Ignoring a stimulus, brain stops responding to it
Habituation
Depolarized (+ in); neural impulse firing
Action Potential
Polarized (-) not firing
Resting Potential
Received messages from other neurons
Dendrites
Scan: blood and oxygen flow to active parts/glucose metabolism — show function, brain activity at higher resolution than PET
fMRI
Electrodes placed on brain to measure brain wave patterns and activity
EEG
Inhibitory neurotransmitter, helps calm nervous activity
GABA
Excitatory neurotransmitter, excess results in migraines
Glutamate
Functions, memory, movement, learning, deficit causes Alzheimer’s
Acetylcholine
Paradoxical sleep/rapid eye movement, dreams, rapid breathing, heart rate, brain waves — awake mode, less to more
REM sleep
Hypagogic sensations
NREM1
Spindles/K complexes
NREM 2
Deepest sleep/night terrors
NREM3
Under production causes Parkinson’s, Over production causes schizophrenia
Dopamine
Lobe for seeing
Occipital Lobe
Lobe for hearing
Temporal Lobe
Somatosensory cortex/touch and pain
Parietal Lobe
Executive functioning/planning higher level/emotional control
Frontal Lobes
Study across age groups, short period of time
Cross-sectional study
Study of one group over a long period of time
Longitudinal study
Fight or flight released by adrenal gland
Norepinephrine
Three types of cones: red, blue, and green. A color other than those three triggers a combination of those colors
Trichromatic theory
Monitors balance and location and position of the head in the cochlea
Vestibular system
Monitors and coordinates position of body parts sent from sensory neurons in joints and muscles
Kinesthetic sense
Small nerve fibers send a pain message to the spinal cord and then to the brain. Large nerve fibers block the pain, noiceptors
Gate control theory of pain
