Hippocampal acute slice electrophysiology seven days following Sham or ACA procedure.

<p><b>A)</b> Mean (± S.E.M.) input/output curve (I/O) of fEPSP amplitudes across stimulation intensities (4–15 V) in control and ACA animals (not normalized). <b>B)</b> Example tracings of sham fEPSP recorded in the CA1 stratum radiatum region of hippocampal slices, before (black) and after (gray) LTP-induction. <b>C)</b> Average slope of fEPSP (averaged to the 30 min pre-tetanus values) before and after the induction of LTP. LTP was induced by 100-Hz tetanic stimulation for 1 s and is indicated by the arrow. <b>D)</b> Example tracings of sham paired-pulse response. <b>E)</b> Average fold increase of paired-pulse response; Stimulation 2 (S₂)/Stimulation 1 (S₁) amplitude following sham and ACA procedures (*<i>p</i><0.05, n = 6).
