FIGURE 7.

Bradykinin‐induced inward currents in the nodose neurons acutely isolated from adult female rats. The inward currents were recorded under voltage‐clamp configuration with gap‐free protocol in the neurons identified by electrophysiological validation, such as the action potential (AP) firing threshold, AP duration, the maximal up and downstroke velocity with or without the repolarization hump (the details see the Figure S7). (A1‐A4): The four representative recordings of inward currents with significant instant firing during the depolarization in the presence of 30 nM of BK (arrowheads) in identified myelinated Ah‐types; (B1‐B4): The four representative recordings of inward currents without significant instant firing during the depolarization in the presence of 300nM of BK (arrowheads) in identified unmyelinated C‐types. The vertical scale bar in the (A1) and (B1) apply for all other recordings
