Check out the Neuron and Cell publications from Jerry C.P. Yin and Tim
Tully. They did the Drosophila CREB work showing the divergent effects
of two splice variants, CREB activator and CREB repressor, on
protein-synthesis dependent long-term memory. Over-expression of CREB
activator essentially made the flies super-smart (odor-o-graphic
memory) and expression of the CREB blocker form nixed the flies'
ability to develope long-term memory.
Since this is such an excellently presented case of CREB's involvement
in long-term memory in a live behaving animal, you really needn't worry
