    Localization of a short-term memory in Drosophila (2000)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2000-04-28
    Description: Memories are thought to be due to lasting synaptic modifications in the brain. The search for memory traces has relied predominantly on determining regions that are necessary for the process. However, a more informative approach is to define the smallest sufficient set of brain structures. The rutabaga adenylyl cyclase, an enzyme that is ubiquitously expressed in the Drosophila brain and that mediates synaptic plasticity, is needed exclusively in the Kenyon cells of the mushroom bodies for a component of olfactory short-term memory. This demonstrates that synaptic plasticity in a small brain region can be sufficient for memory formation.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Zars, T -- Fischer, M -- Schulz, R -- Heisenberg, M -- New York, N.Y. -- Science. 2000 Apr 28;288(5466):672-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Theodor Boveri Institut fur Biowissenschaften, Lehrstuhl fur Genetik, (Biozentrum) Am Hubland, D97074, Wurzburg, Germany.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/10784450" target="_blank"〉PubMed〈/a〉

    Visual pattern recognition in Drosophila is invariant for retinal position (2004)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2004-08-18
    Description: Vision relies on constancy mechanisms. Yet, these are little understood, because they are difficult to investigate in freely moving organisms. One such mechanism, translation invariance, enables organisms to recognize visual patterns independent of the region of their visual field where they had originally seen them. Tethered flies (Drosophila melanogaster) in a flight simulator can recognize visual patterns. Because their eyes are fixed in space and patterns can be displayed in defined parts of their visual field, they can be tested for translation invariance. Here, we show that flies recognize patterns at retinal positions where the patterns had not been presented before.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Tang, Shiming -- Wolf, Reinhard -- Xu, Shuping -- Heisenberg, Martin -- New York, N.Y. -- Science. 2004 Aug 13;305(5686):1020-2.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Institute of Biophysics Academia Sinica, 15 Datun Road, Chaoyang, Beijing 100101, P.R.

    Associative odor learning in Drosophila abolished by chemical ablation of mushroom bodies (1994)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1994-02-04
    Description: The corpora pedunculata, or mushroom bodies (MBs), in the brain of Drosophila melanogaster adults consist of approximately 2500 parallel Kenyon cell fibers derived from four MB neuroblasts. Hydroxyurea fed to newly hatched larvae selectively deletes these cells, resulting in complete, precise MB albation. Adult flies developing without MBs behave normally in most respects, but are unable to perform in a classical conditioning paradigm that tests associative learning of odor cues and electric shock. This deficit cannot be attributed to reductions in olfactory sensitivity, shock reactivity, or locomotor behavior. The results demonstrate that MBs mediate associative odor learning in flies.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉de Belle, J S -- Heisenberg, M -- New York, N.Y. -- Science. 1994 Feb 4;263(5147):692-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Theodor-Boveri-Institut fur Biowissenschaften, Lehrstuhl fur Genetik, Universitat Wurzburg, Germany.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8303280" target="_blank"〉PubMed〈/a〉
