Neuronal wiring diagram of an adult brain Paper

Dorkenwald S, Matsliah A, Sterling AR, et al. (FlyWire Consortium)

Nature, 2024

Abstract

The first complete connectome of an adult brain, reconstructed from a female Drosophila melanogaster. Contains ~140,000 neurons and ~50 million synapses, enabling comprehensive circuit analysis across the entire central brain.

Synaptic cleft segmentation in non-isotropic EM Methods

Heinrich L, Funke J, Pape C, Macrina T, et al.

MICCAI, 2018

Abstract

Neural network approach for detecting synaptic clefts in anisotropic electron microscopy data. Ground Truth annotations from this work form the basis for synapse detection in FAFB.

Our Contribution Synapse Ground Truth annotations
Focus Synapse detection, cleft segmentation
