Olfactory associative learning in Caenorhabditis elegans is impaired in lrn-1 and lrn-2 mutants.

Behavioral neuroscience - 1 Apr 1999

Morrison G E, Wen J Y, Runciman S, van der Kooy D

Abstract excerpt

The C. elegans mutants, lrn-1 and lrn-2, are impaired in associative learning using conditioned taste cues. Both mutants are defective in associative learning about appetitive and aversive events, indicating that lrn-1 and lrn-2 exert effects across motivational boundaries. In a new olfactory associative learning paradigm, in which wild type worms learn to avoid a previously attractive diacetyl odor after it has...
