  • Values are means ± SE with number of cells in parentheses. Washout values are taken >30 min after theta frequencies (TBS) and exclude cells with mono- or polysynaptic long-term potentiation (LTP) but include measurements in 2 cells made after short-term potentiation (STP) had declined to baseline. MCPG, (R, S)-α-methyl-4-carboxyphenylglycine; AHP, afterhyperpolarizing potential.
