I am reading the paper Cooperative subnetworks of molecularly similar interneurons in mouse neocortex and have encountered the term: "Unitary (excitatory or inhibitory) post synaptic potential". I know what is an excitatory (or inhibitory) post synaptic potential. But what does the unitary refers to?

    $\begingroup$ Unitary EPSPs is the EPSP contributed by a single presynaptic fibre. $\endgroup$ – user24284 Apr 27 '17 at 12:55
  • $\begingroup$ Does it mean a single synapse? $\endgroup$ – user135172 Apr 27 '17 at 13:01
  • $\begingroup$ No, it means a single presynaptic fibre (which can make several synapses with a postsynaptic fibre). $\endgroup$ – user24284 Apr 27 '17 at 13:02
