Prenatal stress does not modify the intrinsic excitability of layer II/III pyramidal neurons.

<p>(A) Example of a response of a cell from a stressed rat (upper trace) to a depolarizing current pulse (lower trace). (B) Example of an injected current vs. spiking rate relationship in a cell shown in (A). (C) The mean firing threshold (± SEM) and (D) the mean gain (a slope of injected current vs. spiking rate relationship; ± SEM) of pyramidal neurons prepared from control (white bars; 19 cells from 5 rats) and prenatally stressed animals (black bars; 16 cells from 5 rats). The differences are not significant.
