fly_larva — Drosophila larva brain (2023)
- Description
A complete synaptic map of the brain connectome of the larva of the fruit fly Drosophila melanogaster. Nodes are neurons, and edges are synaptic connections, traced individually from brain image sections using three-dimensional electron microscopy–based reconstruction. A directed edge points from the presynaptic to the postsynaptic neuron (from the rows to the columns of the published connectivity matrices), with a separate edge for each type of connection between the pair, according to the presynaptic and postsynaptic compartments (
'ad': axo-dendritic,'aa': axo-axonic,'dd': dendro-dendritic,'da': dendro-axonic), so that a pair of neurons can be connected by several parallel edges; each edge is weighted by its number of synapses. Node metadata include the neuron hemisphere, hemispherical homologue, cell type, annotations, and inferred cluster. Edge metadata include the type of interaction ('aa','ad','da','dd'), and synapse count.
