Switching gears: translational mastery of transcription during memory formation.

A critical molecular requirement underlying many forms of long-lasting synaptic plasticity and memory is the de novo synthesis of mRNAs and proteins. In a recent paper in Cell, Costa-Mattioli et al. present data from a pharmacogenetic study that places a key regulatory event in the "neural decision" to undergo these persistent neuronal changes under translational control mediated by eIF2alpha.
