Biology Flashcards
left hemisphere
dominant; letters, words, language, speech, reading, writing, math, complex voluntary movement
right hemisphere
faces, emotions, music, creativity, sense of direction, spatial
oligodendrocytes
provide myelin in cns
schwann cells
provide myelin in pns
resting potential
inactivated state of neuron; negative charge and does not let positive charged ions in
presynaptic cell
fires and releases neurotransmitters from its terminal buttons
postsynaptic cell
detect the presence of neurotransmitters and cause channels to open
excitatory postsynaptic potential
positive charges from outside allowed in cell - called depolarization, increase chance cell will fire
inhibitory postsynaptic potential
positive charges let out - hyperpolarized, decrease chance a cell will fire
luteinizing hormone
associated with ovulation, release of egg
follicle stimulating hormone
secreted by pituitary; stimulates growth of ovarian follicle -
stage 2 sleep
theta waves; light sleep, EEG activity shows sleep spindles; k complexes
stage 3
delta waves; deep sleep, steeper sleep spindles
sleep waves
beta, alpha, theta, theta, delta, delta, rem
BATT-DD
james lange theory of emotion
physiological reaction and then become aware of emotions
cannon bard theory
physiological arousal and cognitive experience of emotion - occur simulataneously
schachter singer theory
interaction between changes in physio arousal and cognitive interpretations
order of electrical activity when passing through cell
dendrite, cell body (soma), axon hillock, axon, terminal buttons
Galton
individual differences
weber
just noticeable difference
signal detection theory
suggests that other non sensory factors influence what the subject says she senses
swets
Stevens
stevens power law - relates intensity of the stimulus to intensity of sensation
commonalities of sensory systems
receptors, transduction, projection areas
young helmholtz
trichromatic theory of color - 3 different types of color receptors - red, blue, and green
