| abstractText | To investigate the roles phosphatases play in hippocampal- dependent memory, we studied transgenic mice overexpressing a truncated form of calcineurin. These mice have normal short-term memory but defective long-term memory evident on both a spatial task and on a visual recognition task, providing genetic evidence for the role of the rodent hippocampus in spatial and nonspatial memory. The defect in longterm memory could be fully rescued by increasing the number of training trials, suggesting that the mice have the capacity for long-term memory. We next analyzed mice overexpressing calcineurin in a regulated manner and found the memory defect is reversible and not due to a developmental abnormality. Our behavioral results suggest that calcineurin has a role in the transition from short-to long-term memory, which correlates with a novel intermediate phase of LTP. |
