MicroRNAs are a class of small RNA molecules that regulate the expression of a wide variety of genes. In this issue of Neuron, Rajasethupathy and colleagues identify 170 distinct microRNAs in Aplysia, including one, miR-124, that plays a critical role in the regulation of signaling molecules underlying synaptic plasticity and memory. © 2009 Elsevier Inc.
