Table 2.

Number of slices from 30- to 40-day-old offspring showing PTP, STP, and LTP of f-EPSP

	Vehicle-exposed (n* = 22, from 10 rats)		WIN-exposed (n* = 21, from 9 rats)
	n†	%	n†	%
PTP	22	100.00	21	100.00
STP	22	100.00	17	80.95
LTP	20	90.91	3	14.29‡

Values indicate the occurrence of tests where slices exhibited temporal changes of EPSP as described in Materials and Methods. 

^*Number of slices tested. 

^†Number of slices exhibiting changes. 

^‡ P < 0.001 with respect to vehicle (Fisher's exact test).
