Synaptic Transmission Study Question Bank

Questions: 16 | Attempts: 2050 | Last updated: Mar 21, 2025

Sample Question
Sequential excitatory postsynaptic potentials (EPSPs) from a given presynaptic terminal will be most effective at bringing a postsynaptic neuron to threshold when:

Inhibitory inputs are present on the soma

EPSPs are arriving very close together in time

EPSPs are arriving from presynaptic cells that form synapses at a great distance from the axon hillox
