Unformatted text preview: a. Ca 2+ ions act as second messengers during synaptic transmission. b. Following neurotransmitter release, large numbers of ion channels in the postsynaptic cell open and close almost simultaneously. c. The intracellular Ca 2+ concentration at the active zone changes significantly during an action potential. d. Choline cannot activate the acetylcholine receptor. e. EPSPs at the NMJ are much larger than those in the CNS. 4. Synaptic transmission a. Glutamate predominates at excitatory synapses in the CNS. b. Inhibiting its M-channels will make a neuron more excitable. c. NMDA receptors are essential to long term potentiation. d. Glutamate can mediate slow synaptic transmission. e. Neurons in the CNS receive predominantly either excitatory or inhibitory input....
