Evoked firing properties of APP/PS1 PCs. HoxhaEriola BodaEnrica MontaroloFrancesca ParolisiRoberta TempiaFilippo 2012 <p>(<b>A</b>) Wild-type (blue) and APP/PS1 (red) PC evoked action potential firing. In the wild-type trace, the first three interspike intervals (ISI) are shown. (<b>B</b>) Mean latency of the first spike for PCs from wild-type (n = 14) and APP/PS1 (n = 20). The difference is not significant (P>0.05). (<b>C</b>) Plot of the first three ISIs of wild-type (n = 14) and APP/PS1 (n = 20) mice PCs. The second and third ISIs are significantly prolonged in APP/PS1 mice (*p<0.05, t test).</p>
