Amplitude and Latency of Early and Late components in the Different Recording Sites in Naive Animals

Component	Parameter	Structure
		Anterior part of piriform cortex	Posterior part of piriform cortex	Lateral entorhinal cortex	Dentate gyrus
Late	Amplitude (μV)	296 ± 82	616 ± 63b	262 ± 52	333 ± 59
	Latency (msec)	58.9 ± 2.1	54.7 ± 1.6a	59.2 ± 1.7	63.3 ± 1.2a
Early	Amplitude (μV)	642 ± 74bd	408 ± 27bc	194 ± 18b	286 ± 33b
	Latency (msec)	7.7 ± 0.1b	9.7 ± 0.1b	12.4 ± 0.2b	35.8 ± 1.3b

^aP < 0.01, ^bP < 0.005, significant difference with the values in the same rcw; ^cP < 0.01, ^dP < 0.005: significant difference with late-component amplitude in the same column.
