Figure 4. Older rats exhibit more anxiety than young rats.

Figure 4

Rats were treated on P4 with PBS or E. coli, and tested for anxiety at 2 months (A) or 16 months (B) of age. Time spent in the open vs. closed arms of the elevated plus maze did not differ between neonatal treatment groups at either age, but 2 month old rats spent significantly more time in the open arms than older rats, **p<0.05.
