Prenatal stress impairs the induction of LTP.

<p>(A) Plot of the amplitude of FPs (mean ± SEM) recorded in slices obtained from control rats (white circles) and from rats subjected to prenatal stress (black circles). Arrows denote the time of theta-burst stimulation (TBS, repeated 3 times). Insets show superposition of FPs recorded during representative experiments before and after TBS at times indicated by numbers. (B) Mean (± SEM) amplitude of FPs recorded between 60–75 min after TBS in slices prepared from control (n = 10) and prenatally stressed (n = 10) rats. The numbers on the bars indicate the numbers of slices in each group. *** p < 0.001; Mann-Whitney U test.
