MAP

function testSynapse

% testSynapse tracks the quantity of available transmitter vesicles

%  the computations are single channel using the first frequency

%  in the targetFrequency box of the expGUI.

% For, speed this function uses only probability and HSR fibers.

% This cannot be changed because of the way AN_IHCsynapse is coded.This).
