|
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 |
|
|
sensitization |
an increase in response to mild stimuli as a result of exposure to more intense stimuli |
|
|
specificity |
property that highly active synapses become strengthened and less active synapses do not |
