Morphology of a sensory neuron in Drosophila is abnormal in memory mutants and changes during aging.

Proceedings of the National Academy of Sciences of the United States of America - 15 Aug 1991

Corfas G, Dudai Y

Abstract excerpt

Several mutations in Drosophila impair learning and the cAMP cascade. We report here that the fine morphology of an identified mechanosensory neuron is abnormal in two of these mutants, dunce (dnc) and rutabaga (rut). The neuron innervating the antero-notopleural bristle was filled with horseradish peroxidase and studied at the light- and electron-microscopy level. In the mutants dnc and rut, this neuron has an...
