Expression of CaMKII^{dsRNA.Scer\UAS} under the control of Scer\GAL4^VGlut-OK371 results in a decrease in bouton number/area for type Ib boutons at the larval neuromuscular junction.

Flies expressing CaMKII^{dsRNA.Scer\UAS} under the control of either Scer\GAL4^ey-OK107, Scer\GAL4^c305a, Scer\GAL4^Mef2.247 or Scer\GAL4^CaMKII.7 show normal learning (measured as 2 minute memory) in an olfactory aversive conditioning assay.

Flies expressing CaMKII^{dsRNA.Scer\UAS} under the control of either Scer\GAL4^ey-OK107, Scer\GAL4^c305a or Scer\GAL4^Mef2.247 show normal middle-term memory (measured 3 hours after one cycle of training) in an olfactory aversive conditioning assay.

Flies expressing CaMKII^{dsRNA.Scer\UAS} under the control of either Scer\GAL4^ey-OK107, Scer\GAL4^c305a or Scer\GAL4^Mef2.247 show severely reduced long-term memory (measured 24 hours after 5 cycles of spaced training) in an olfactory aversive conditioning assay.

1 day memory is impaired after spaced training, but not after massed training in an olfactory associative conditioning assay in flies expressing CaMKII^{dsRNA.Scer\UAS} under the control of Scer\GAL4^G0431. The defect in memory after spaced training is still seen if the temperature sensitive Scer\GAL80^ts.αTub84B allele is used to restrict Scer\GAL4 expression to the adult stage.

Flies expressing CaMKII^{dsRNA.Scer\UAS} under the control of Scer\GAL4^CaMKII.7 show a near-complete loss of long-term olfactory memory, while short-term memory is unaffected.
