title: Fluctuating responses at a central synapse: n of binomial fit predicts number of stained presynaptic boutons.
abstract: Binomial predictions provided a better description than the Poisson law of fluctuating unitary inhibitory postsynaptic potentials evoked in the goldfish Mauthner cell by impulses in presynaptic interneurons. The number of terminal boutons established on this target cell by each horseradish peroxidase-filled interneuron corresponded to the value of the binomial parameter n.
