THE intrinsic membrane properties of giant neurons of the caudal pontine reticular nucleus (PnC) were evaluated in a rat brain slice preparation. These neurons show low RP levels, long membrane time constants, low membrane resistance, tonic AP firing, and a lack of rectification behavior. The results are compared to those measured in adjacent areas of the reticular formation and discussed for their impact on triggering and modulating the acoustic startle response.
