Reduced growth cone motility in cultured neurons from Drosophila memory mutants with a defective cAMP cascade.


Drosophila memory mutants dunce (dnc) and rutabaga (rut) are known to have altered intracellular cAMP levels, nerve terminal growth, and plasticity of synaptic transmission. Because the growth cone is responsible for neurite outgrowth and synaptogenesis, video microscopy was used to examine growth cone morphology and behavior of mutant neurons in larval CNS… (More)
