Abbreviations: Nwk, Nervous wreck; RP, reserve SV pool; RRP, readily releasable SV pool. Note that 22 thin sections from Canton-S boutons and 72 thin sections from nwk2 null mutant boutons were examined.
a
SVs localized within 200 nm from the stub of T-AZs were considered the RRP.
b
SVs localized farther than 200 nm from the stub of T-AZs were considered the RP.
