From: A single baroreceptor unit consists of multiple sensors
Typical baroreceptor unit response recorded in the left depressor nerve of an anesthetized, open-chest and mechanically ventilated rabbit. Traces are: BP, arterial blood pressure; IMP/s, unit activity, impulses counted at a bin width of 0.05 s; IMP, unit activity; Paw, airway pressure. A, control; B, unit response to intravenous injection of phenylephrine (10 mM, 0.2 ml, indicated by the two arrows on top of the BP trace). Time periods between B–C, C–D, and D–E were 40, 10, and 30 s, and between E–F was 3 min. Please note that the unit discharges at very high frequencies as the BP is maintained at a high level (C); unit activity became irregular before inactivating (D). Please also note that A, E, and F have the same paper speed, so do B, C and D.
