Their solution involves the very gradual incorporation of the new information from the
hippocampus into the neocortical structure (i.e., long-term memory). Hippocampal
representations very gradually train the neocortex. This is very likely correct. The problem,
as we will show below, is that no matter how slowly the hippocampal information is passed
to the neocortex, radical forgetting of the old information can result, unless a way is found to
interleave the already stored neocortical patterns with the new patterns being learned
