Postsynaptic plasticity of cholinergic synapses underlies the induction and expression of appetitive memories in Drosophila

Carlotta Pribbenow, Yi-chun Chen, Michael-Marcel Heim, Desiree Laber, Silas Reubold, Eric Reynolds, Isabella Balles, Raquel Suárez Grimalt, Carolin Rauch, Jörg Rösner, Tania Fernández-d.V. Alquicira, David Owald,

In vertebrates, memory-relevant synaptic plasticity involves postsynaptic rearrangements of glutamate receptors.
