Which of these is least likely to trigger an action potential in a post-synaptic cell?  A)EPSPs and IPSPs arrive simultaneously at multiple synapses.  B)The other choices are equally likely to trigger an action potential. C)Single EPSPs arrive simultaneously at multiple synapses.  D)Multiple EPSPs arrive rapidly at a single synapse.

Which of the following occurs during synaptic transmission? Select ALL that apply A) vesicles filled with neurotransmitter are released into the synapse B) an action potential travels through a neuron like a wave C) neurotransmitter binds to receptors on the sending neuron D) neurotransmitter binding to a receptor triggers the opening of an ion channel E) ions enter the receiving neuron's dendrites

Calcium entry through NNDA receptor can potentiate synaptic transmission through the following mechanisms EXCEPT:  a.) Insertion of AMPA receptors to postsynaptic membrane b.) Synthesis of NO to increase presynaptic transmitter release c.) Phosphorylation of AMPA  receptors d.) Slowing down glutamate reupdate, so it remains longer in the synapse

Which of the following statements concerning synapses is FALSE? O A) Modulation of synaptic strength can be presynaptic of postsynaptic B) High frequency stimulation in the presynaptic neuron often leads to DECREASED neurotransmitter release O C) Modulation of synaptic strength can either be short term, lasting seconds, or long term, lasting as long as a lifetime. D) Agonists are drugs that mimic neurotransmitters and antagonists are drugs that block the action of neurotransmitters O E) Certain drugs prevent the reuptake of neurotransmitter from the synapse
