Comparison of the neurophysiological properties of CA3 pyramidal cells in experimental and control rats

	Control	Experimental
n	4	5
Vm, mV	−65  ± 4.2	−66  ± 3.6
Rm, MΩ	180  ± 21	161  ± 14.6
Spike amp, mV	73.9  ± 2.7	80.4  ± 3.2
Spike duration, ½ amplitude, msec	1.3  ± .01	1.1  ± .03
Intrinsic burst duration, msec	60.3  ± 1.4	63.2  ± 3.1
Number of spikes per burst	2.5  ± 0.5	2.3  ± 0.3

n = number of cells. Data are presented as mean ± SEM. Differences between all measures made in saline-infused (control) and TTX-infused (experimental) rats were not significant (p > 0.05).
