AMPA receptor
a glutamate receptor that can respond to a-amino-3-hydrozy-5-methyl-4-isoxazolepropionic acid (AMPA)
associativity
property that a weak input paired with a stronger input enhances its later response
BDNF (brain-derived neurotrophic factor)
a neurotrophin similar to nerve growth factor
cooperativity
tendency for nearly simultaneous stimulation by two or more axons to produce long-term potentiation much more effectively than stimulation by just one
habituation
decrease in response to a stimulus that is presented repeatedly and accompanied by no change in other stimuli
Hebbian synapse
a synapse that increases in effectiveness because of simultaneous activity in the presynaptic and postsynaptic neurons
long-term depression (LTD)
a prolonged decrease in response at a synapse where the axons have been less active than certain other axons afferent to that neuron
long-term potentiation (LTP)
phenomenon that when one or more axons connected to a dendrite bombard it with a rapid series of stimuli, some of the synapses become more responsive to new input of the same type for minutes, days, or weeks
NMDA receptor
a glutamate receptor that can respond to the drug N-methyl-D-aspartate (NMDA)
retrograde transmitter
a transmitter released by a postsynaptic cell that travels back to the presynaptic cell to modify it
