Table 2.

Percentage of animals able to successfully complete the learning/memory task

	4 Wks	8 Wks	12 Wks	16 Wks
Sham	64	100	100	100
FPI	13^a	53^a	78	89
FPI and HH	0^a	18^a	57^a	71

FP, fluid percussion; HH, hemorrhagic hypotension.

p < .05 in comparison to sham. Values are percentages. There were significant injury related deficits in both the isolated FP and the FP and HH groups up to 8 weeks postinjury, but only the FP and HH group had a significantly lower percentage of animals able to complete the task at 12 weeks postinjury.
