Storing Information in the Nervous System

Cards (8)

  • is excited by the neurotransmitter glutamate, but it can also respond to a drug called a-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid
    AMPA receptor
  • Pairing a weak input with a strong input enhances later response to the weak input
    associativity
  • brain-derived neurotrophic factor, a neurotrophin similar to nerve growth factor

    BDNF
  • —Nearly simultaneous stimulation by two or more axons produces LTP much more strongly than does repeated stimulation by just one axon.
    cooperativity
  • is a decrease in response to a stimulus that is presented repeatedly and accompanied by no change in other stimuli.
    habituation
  • A synapse that increases in effectiveness because of simultaneous activity in the presynaptic and postsynaptic neurons is called a ___________
    Hebbian synapse
  • a prolonged decrease in response at a synapse, occurs for axons that have been less active than others
    long-term depression (LTD)
  • One or more axons connected to a dendrite bombard it with a rapid series of stimuli.
    long-term potentiation (LTP)
