Virtual Fly Brain brings together data from multiple electron microscopy (EM) resources, providing access to high-resolution neuroanatomical datasets. These datasets include complete EM volumes of Drosophila brains and ventral nerve cords, neuron reconstructions, connectivity information and neurotransmitter predictions. Data can be visualised using the web browser or accessed programmatically via APIs.
Comparison Table of Integrated Datasets
