Figure 1. Percent freezing to the context in the pre-exposure task does not differ among groups.
Rats were treated on postnatal day (P) 4 with PBS or E. coli, and tested for memory at 2 month or 16 month of age using a task which requires the animal to make a simple association between a shock and exploration of a novel environment the previous day. There were no significant differences as a consequence of either age or neonatal treatment.
