Characteristics of deep layer EC intracellular evoked responses

	Control	Epileptic

n ^*	30	44
Total duration of depolarization, ms	8.6 ± 1.3	256 ± 39^{^†}
Number of APs per response	1 ± 0	13 ± 4^{^†}
Clonic response present, %	0	10^{^‡}
With GABA_A and GABA_B IPSPs,^ρ %	77	0^{^‡}
With GABA_A IPSP only,^ρ %	13	0^{^‡}
Without IPSPs, %	10	100^{^‡}
AP stimulation threshold to angular bundle stimulation, V	40 ± 6.0	21 ± 6.17
AP stimulation threshold to superficial stimulation, V	7.8 ± 3.4	6.8 ± 1.8

Values for continuous variable are means ± SE. Continuous variables compared by ANOVA and proportions compared by Fisher's exact test. AP, action potential; GABA_A and GABA_B, γ-amino butyric acid-A and -B.
↵* n, number of responses with the given inhibitory postsynaptic potential (IPSP). ^† Difference between control and epileptic is statistically significant at P < 0.05. ^‡ Difference between control and epileptic is statistically significant at P < 0.001. ^ρ GABA_A and GABA_B are early and late IPSPs, respectively.
