We test the hypothesis that the stability and precision of context and visual discrimination memories depend upon interactions between the hippocampus (HPC) and other memory storage networks. In four experiments we tested the properties of memories acquired in the absence of the HPC. Long-Evans male rats were exclusively used in all experiments. Experiment 1 evaluated acquisition and retention of context fear memories in rats with prior partial or complete HPC damage. Confirming an earlier report (Zelikowsky, et al., 2012) a very small but statistically reliable slowing in a single session of context fear conditioning was found after HPC damage. In contrast, retention of context fear memory was normal after HPC damage up to 30 days after learning. In Experiment 2 we found that discrimination between a context paired with foot shocks and a different context never paired with foot shock was retained normally for 15 days. In Experiment 3 we replicated the finding of intact context discrimination for at least ...
