Low dose SST produces “quantal slowing” of fictive inspiration. A. Integrated fictive inspiratory output of C4 before (control) and after bath application of 10−13 M somatostatin. B. Instantaneous inspiratory period before and during SST application in same preparation as A. Note the clustering of periods at near integer multiples of the control baseline period. C. Period histograms of four different preparations in the presence of 10−13 M SST showing “quantal” slowing. Tn = duration of a cycle, Tref = duration of a control cycle.
