摘要
Long-term memory formation requires new synthesis of proteins that regulate synaptic plasticity. Recently, microRNAs （rniRNAs） have been identified as master regulators of protein synthesis, miRNAs are an extensive class of small noncoding RNAs （21-25 nt） that preferentially bind to the 3＇ un- translated regions （UTRs） of mRNAs, thereby either inducing translational repression or degradation of the target mRNA. In the nervous system, miRNAs control diverse processes,
