Behavioral effects of lipopolysaccharide. (a) Non-social and (b) social pokes exhibited by rats 3 hr, 6 hr, or 24 hr after injection with either 100 μg/kg lipopolysaccharide (LPS; black squares) or saline (white circles). In this figure (as well as in all subsequent figures), data are expressed as mean ± S.E.M. Plus signs (+) indicate a significant difference between saline- and LPS-exposed animals at a given testing time.
