Electrophysiological parameters for spontaneous putative synaptic events during the down state in current clamp (PSP) and voltage clamp (PSC)

	Spiny projection neuron (n = 11)	Fast spiking interneuron (n = 7)
PSP amplitude (mV)a	2.0 ± 0.31	1.7 ± 0.35
PSP rise time (msec)	7.0 ± 0.7	5.4 ± 1.4
PSP IEI (msec)	141 ± 19	70 ± 13
PSP slope (mV/msec)	469 ± 103	323 ± 49
PSC amplitude (pA)a	−14 ± 3	−26 ± 9
PSC rise time (msec)	1.2 ± 0.1	1.0 ± 0.1
PSC IEI (msec)	321 ± 78	131 ± 39
PSC slope (pA/msec)	−11.8 ± 2.6	−30.45 ± 11.0

Results are mean ± SEM. No significant differences were found (MANOVA). PSP,F = 1.62;p = 0.24. PSC,F = 1.05; p = 0.44.
