L060, the enantiomer of LEV, does not reduce normalized EPSC amplitudes. A: average normalized EPSC amplitudes during an 80-Hz train of 20 stimulation pulses. B: averages of the normalized amplitudes of the 2nd EPSCs and 18th through 20th EPSCs of the 80-Hz trains for slices incubated for 3 h in 300 μM L060 compared with previous 3-h 300 μM LEV data. All data shown are means ± SE (n = nos. shown in bar diagram are from at least 3 different animals per group; P values from Student's t-test). *Significant difference.
