  • Numbers in parentheses, number of pairs. Values are mean ± SD;

  • **p < 0.01.

  • aIncludes some data from the work of Morishima and Kawaguchi (2006) [latency, rise time, decay time constant, amplitude, CV of the amplitude, n = 24; paired-pulse ratio, n = 15].

  • bData taken from Morishima and Kawaguchi (2006).

  • cTime from 20% to 80% of EPSC peak amplitude.
