  • Results of quantal analysis of synaptic currents for the tonic axon at three recording sites. Freq., stimulation frequency; Event, number of quantal units counted per stimulus; Obs., observed number of each event; Theoretical, best-fitted distributions; n andp, binomial parameters for best-fitted binomial distributions according to the Akaike Information Criterion (AIC); Embedded Image and Embedded Image, mean values of binomial parameters resulting from the Bootstrap method; m, calculated value for mean quantal content.
