Comparison of prelimbic cortex- and infralimbic cortex-evoked responses in the BLA

Stimulation intensity	Inputs to projection neurons		Inputs to interneurons
	Infralimbic cortexn = 10 (%)	Prelimbic cortex n = 11 (%)	Infralimbic cortex n = 14 (%)	Prelimbic cortexn = 13 (%)
Threshold (T)	6.8  ± 1.2	6.4  ± 1.1	9.5  ± 1.7	5.8  ± 0.9
0.1 mA above T	22.8  ± 7.6	26.1  ± 6.5	60.0  ± 12.5	64.5  ± 15.3
0.2 mA above T	52.1  ± 10.5	36.1  ± 7.8	115.9  ± 15.7	138.7  ± 24.9
0.3 mA above T	60.7  ± 11.5	46.9  ± 7.9	183.3  ± 28.3	214.5  ± 44.4
0.4 mA above T	62.3  ± 10.2	44.6  ± 8.2	214.0  ± 68.6	241.9  ± 51.2

Percent values in this table represent the number of spikes per 100 stimuli. Significant differences were not observed between infralimbic cortical and prelimbic cortical inputs to projection neurons or to interneurons (ANOVA; p > 0.05).
