Work Package 5


EBRAINS Modelling Services

What we do


This Work Package manages the overall architecture integrating scientific software into EBRAINS. It comprises the development and advancement of applications for brain modelling and simulation, analysis of neural activity data, model validation, and visualisation. The deployed services will combine the applications into comprehensive workflows, they will enable multiscale co-simulation of brain processes and closed-loop neuroscience experiments/in silico/, which in turn support R&D on embodied AI and robotics. WP5 delivers the e-infrastructure for operating all services of the Project on the computing infrastructure allocated to them.

How we are organised


WP5 comprises Service Category 3 (SC3) - Brain modelling and simulation workflows: integrated tools to create and investigate models of the brain, SC4 - Closed loop AI and robotics workflows: design, test and implement robotic and AI solutions tasks, and tasks that will deliver the necessary e-infrastructure for all service categories of the Project.

A workflow for constructing and optimizing data-driven models of subcellular signalling

We have created a software tool-set that helps with creation of models, storage of models, auto-generation of model code, parameter estimation for those models (using lab data), global sensitivity analysis of the model with respect to the parameters, and model based prediction.

A set of fully operational workflows for cellular level in silico experiments on single cell, small microcircuits, and large-scale circuit models, which will be fully integrated into EBRAINS, complemented by tutorials/user guides, and publicly available for users

website is online and all workflows are operational

Open-source software releases of NEST featuring third-factor learning rules, long axonal delays, revised code for sustainability, co-simulation and visualization interfaces, simulation performance, performance in creation of hierarchical networks, documentation and training material

NEST simulator is continuously developed and was released regularly during SGA3 (see Contribution of T4.13 (via vouchers).

Open-source software releases of Model Validation Web Service including improved browsing and presentation of validation results

We have made regular releases of improvements to the Model Validation web services, including: - rewritten graphical app with EBRAINS authentication and Collaboratory v2 integration - improved homepage with highlighted models - curation dashboard interface for model curators - addition of end-to-end testing using Cypress - bug fixes and performance improvements - migration from Knowledge Graph (KG) v2 to KG v3 with openMINDS schemas.

Open-source software releases of the Education Front end (EduFro) - integration with the SimDaVis, connection to SimVisSuite, curricula, user interface evaluation, high software maturity, documentation and training material (for teachers)

The list of aspects mentioned in the title of the OP has been achieved.

Open-source software releases of Neo including documentation

We have made seven releases of new versions of Neo on the Python package index, with documentation at Neo is also available as part of the EBRAINS software distribution.
