= Pattern separation
A transformation that makes representations of similar inputs less overlapping, helping reduce interference between stored events. It must retain enough information for useful downstream learning and retrieval. The <dentate gyrus> is a proposed substrate, with quantitative input–output evidence from spatial cue-conflict experiments.<CA3 retrieves coherent representations from degraded input: direct evidence for CA3 pattern completion and dentate gyrus pattern separation by Joshua P. Neunuebel and others>[Abstract; simultaneous DG/<CA3> recordings during local/global cue conflict]{ref}
