Evidence for presynaptic expression of nicotine facilitated LTP.

<p>Percent changes induced by 10-pulse bursts in EPSC amplitude, release probability (<i>p</i>), coefficient of variation (<i>CV</i>), and failure rate (<i>FR</i>) between 15 and 20 min after the induction of plasticity in the experiments A-C of Fig. 2 (p<0.01 for all parameters).
