Effects of slice to island conversion onpopulation burst parameters. A. The frequency of population bursts generated by the preBötC was unchanged by cutting away regions of the slice preparation adjacent to the preBötC (see text), thereby converting the section to an island preparation (frequency = 0.33 ± 0.02 Hz in slices vs. 0.37 ± 0.04 Hz in islands; n = 13 of each; paired t-test, P = 0.73). B. By contrast, the amplitude of integrated population bursts decreased by 30.1% with conversion of the slice to the island preparation (*, P < 0.05, paired t-test).
