Neurobiology: From genome and connectome to understanding behavior.

ABSTRACT

Many forms of synaptic plasticity are mediated by changes in the abundance, density, and expression levels of postsynaptic ionotropic receptors. A new study identifies the endogenous ligands of five 'orphan' aminergic ligand-gated ion channels in Caenorhabditis elegans, functionally characterizes these channels, and explores the role of one of them in a simple form of learning.
