Figure 5. Substance-P (SP) injections in preBötC-surface slices.
(A) SP bolus injected in an un-lesioned preBötC-surface slice. XII output magnitude is plotted with cycle period as a time series. (B) Semi-log plot of regularity score (RS) for 30 min after SP injection from the slice preparation in A. RS axis is continuous but plotted with two scales. (C) preBötC-surface slice shown in the acquisition phase (left) and during the ablation phase (right), which were separated by a time gap of 3 hr. After 120 s of quiescence (data point circled in red), SP injection revived the rhythm transiently. (D) Semi-log plot of RS for 15 min after SP injection from the slice preparation in C. Data in C and D were from the same preparation as in Figure 2A.
