cerMz1180 flies show a short-term memory defect. These flies also display a sugar response defect after 21 hours of starvation.
Mutant flies show a decrease in 24 hour long-term memory (LTM) after spaced training, but a normal 24 hour memory capacity after massed training (a conditioning protocol that does not induce LTM). The flies show normal short-term memory after a single training cycle. The LTM defect is recessive.
