| Research Abstract |
Olfactory information in Drosophila is conveyed by projection neurons from olfactory sensory neurons to Kenyon cells (KCs) in the mushroom body. KCs function as coincidence detectors for memory formation, associating odor information with a coincident punishment or reward stimulus. We monitored the neuronal activity after training flies under the microscope with the calcium indicator GCaMP and identified olfactory memory traces in the KCs and in 4th-order neurons that innervate KCs. We also identified the genes required for olfactory memory formation by studying transcriptome of KCs and identified a group of cells required for memory formation by devising a CREB reporter gene.
