Group data summarizing changes of respiratory activity parameters by pharmacologically disrupting GABAAergic and glycinergic inhibition in the pre-BötC of juvenile rat perfused brainstem–spinal cord in situ. A–D, Mean time series from the start of microinjection showing developing changes of normalized TI (A, red curve), TE (B, blue curve), respiratory frequency (fR; C, green curve), and integrated PN discharge amplitude (D, amp, magenta curve), which were computed from integrated phrenic nerve activity for a representative experimental group (n = 6). Solid colored curves are group mean time and normalized parameter values; gray bands are ±1 SEM for the mean normalized parameter values as in Figure 4B–E .
