FlyBrainLab
FlyBrainLab is an open-source interactive computing platform for studying the function of executable circuits constructed from fruit fly brain data. FlyBrainLab is designed with three main capabilities in mind schematically depicted in the figure below:
- (left) 3D exploration and visualization of fruit fly brain data,
- (middle) creation of executable circuits directly from the explored and visualized fly brain data, and
- (right) interactive exploration of the functional logic of the devised executable circuits.
The Architecture of the FlyBrainLab
The main user-side and server-side components of the FlyBrainLab are depicted in the figure below.
The FlyBrainLab user-side components consist of the NeuroMynerva User Interface and the FlyBrainLab Client back-end (Program Execution). The former provides capabilities such as morphology visualization and interactive circuit diagrams, and the latter provides program execution for communicating with the server components.

NeuroMynerva User Interface
NeuroMynerva is the user interface of FlyBrainLab. It is a browser-based application that substantially extends upon JupyterLab to combine the functionality of NeuroNLP for 3D visualization and exploration of fly brain data, and of NeuroGFX for interactively exploring the function of executable neural circuits using interactive circuit diagrams. Both can interoperate with code execution in a Jupyter notebook. NeuroMynerva Code Repository.

NeuroArch Database
NeuroArch is the first graph database that provides a novel data model for representation and storage of connectomic, synaptomic, cell type, activity and genetic data of the fruit fly brain with cross-referenced executable circuits. The NeuroArch data model is the foundation of the integration of fruit fly brain data and executable circuits in FlyBrainLab. NeuroArch Code Repository.

Neurokernel Execution Engine
Neurokernel is the first GPU-based execution engine for emulating the fruit fly brain. It provides a comprehensive API ensuring that independently developed brain circuit models of different brain regions are interoperable and can be combined into a whole brain emulation.
