Average inhibitory strength displayed by noncommon cell pairs according to brain state and cell type and the layer distribution in the EC of the postsynaptic cell

Strength (%) in noncommon pairs	During theta state only		During SO state only
	Target cell type		Target cell type
	PC	Int	PC	Int
EC2	0	42 ± 5 (n = 5)	53 ± 4 (n = 15)	34 ± 3 (n = 6)
EC3	0	35 ± 2 (n = 3)	58 ± 4 (n = 20)	40 ± 5 (n = 7)*
EC5	0	0	58 ± 6 (n = 4)	63 (n = 1)

Values represent mean ± SEM. Tables list the average strength of inhibition displayed by noncommon cell pairs according to the brain state, cell type, and layer location of the postsynaptic cell. We found that the postsynaptic interneurons from the EC3 pairs during SO alone showed significantly lower average inhibition than the corresponding principal cells (*p < 0.01).
