We have previously developed protocols for Caenorhabditis elegans to form short- and long-term associative memories by massed and spaced training, respectively. Here, detailed protocols are described for the conditioning of C. elegans by pairing 1-propanol and hydrochloric acid as conditioned and unconditioned stimuli, respectively, to form aversive associative memory.
