Effects of acute inhibition of C1 neurons on the respiratory and sympathetic activities of in situ preparations of control rats. (A) Raw and integrated (∫) records of tSN, AbN and PN activities from one in situ preparation of control rat transduced with PRSx8-AlstR-GFP-LVV into C1 region before and after arterial perfusion of Alst. PN-triggered averages of tSN and AbN from the same in situ preparation before (Bi) and after (Bii) Alst perfusion. Note that C1 neuronal inhibition reduced the amplitude of the tSN activity during I and PI, but affected neither the inspiratory (PN frequency and amplitude) nor expiratory (AbN) activities. Summary of data showing the changes in the PP (C), HR (D), baseline tSN activity (E) and in tSN activity during I, PI and E2 (F) 5 minutes after perfusion of Alst in in situ preparations of control rats transduced with PRSx8-AlstR-GFP-LVV into the C1 region.
