There's a somewhat similar mechanism which underlies all learning. It's "what fires together, wires together", meaning that neural connections with correlated activity patterns tend to get strengthened over time. While that mechanism operates on what at first seems to be the forward pass, the neurosystem seems to often operate in loops, with "useful" signals continuing to go around for a while to provide the learning signal.
