Synaptic plasticity is believed to underlie the formation of long-term memories, but the mechanisms are not well understood. Elkobi and colleagues now report that induction of PSD-95, a synaptic protein, parallels taste learning, and attenuation of PSD-95 expression in taste cortex blocks learning of novel tastes, but not recollection of familiar ones.
