system that sends messages throughout body thru bloodstream, secretes hormones
endocrine system
neurotransmitter - memory. excitatory
glutamate
pons
transmitter of motor info, coordinating muscles, regulating sleep
central core
functionalism
- what mind does a- what role behavior palys in allowing ppl to adapt to enviornments- how ppl satisfy needs thry behavior- how SOC permits adapt to environment
neurotransmitter - muscle movement, cognitive functioning
acetylocholine
double blind

neurons are either on or off. when there is enough force to be on, neuron fires
he study of the relationship between the physical aspects of stimuli and our psychological experience of them
psychophysics
absolute threshold
smallest intensity of a stim that must be present for it to be detected
difference threshold
smallest level of added or reduced stimulation required to sense a change in stim
law that says that a just noticeable difference is a constant proportion of the intensity of an initial stimulus

bipolar cells
what do ganglion cells do
collect adn summarize visual info which is moved to back of eyeball and sent to brain thru optic nerve
