In TRPV1+ NTS neurons, temperature increased the rate of action potential firing.

<p>(A) In this current clamp recording trace, warming the bath temperature (red) near 37°C briskly increased the rate of action potentials. The shapes of the action potentials changed little from 32°C (blue) to 37°C (red) in expanded traces (B). Resting membrane potential ~ 57 mV at 32°C.
