The complete synaptic-level connectome of a nervous system and experimental connectomics (360G-Wellcome-205038_Z_16_Z)
Animals sense the local environment, learn and remember past events, predict future ones, and combine current and past information to choose appropriate motor responses. Underlying these capabilities is the nervous system, which continuously integrates multiple sources of information and chooses one response in exclusion to all others. Our vision is to study neural circuit function on the basis of known synaptic-level wiring diagrams. In Aim #1, we propose to map the complete wiring diagram of an insect, the Drosophila larval central nervous system, using serial electron microscopy. With the knowledge of the circuits formed by the identified and genetically accessible larval neurons we can study how circuits change either by experience or in disease. In Aim #2 we propose to read out the engrams, the persistent yet reversible structural circuit patterns that form in response to learning and that underlie long-term memories, using associative memory in the larval mushroom bodies as the model system. For circuits to assemble correctly while remaining plastic, hundreds of genes need to work in concert. In Aim #3, we will study the effects of mutations in select genes associated with neural diseases on the synaptic-level circuit structure, causing the disease phenotype.
