title: The precision of remote context memories does not require the hippocampus.
abstract: Although the clarity of many memories fades with time, some memories may maintain their original precision. Here we used a context discrimination procedure to evaluate whether the hippocampus is important in maintaining precision as memories mature. Spared discrimination in hippocampal-lesioned mice indicated that precise, remote context memories may be supported by extra-hippocampal brain regions.
