Work Package 1
The human multiscale brain connectome and its variability – from synapses to large-scale networks and function
What we do
This Work Package develops biologically detailed human brain network models capable of generating brain signals as commonly measured in clinical and research settings. By linking a multiscale human brain atlas to computational modelling, the aim is to better understand the fundamental mechanisms of how the brain generates its behaviour. The validity of the principles and concepts is demonstrated in applications to individual patient data for clinical translation such as in epilepsy, and in cohort data to understand human variability such as in healthy aging and pathology. Neuroethical interrogations guide the debate on the role of the digital twin brain in society.
In WP1, components created in the three-year Work Plans of HBP are being assembled to integrate workflows and produce scientific Showcases demonstrating the added value of the integration in EBRAINS. These components involve a battery of tools (bottom-up, top-down) and workflows comprising data, atlases, multiscale models, and simulators. WP1 Showcases are Showcase 1: Degeneracy in neuroscience - when is Big Data big enough? and Showcase 2: Improving epilepsy surgery with the Virtual Big Brain.
In WP1, we use ICT (Information and Communication Technology) simulation science to better understand brain function and improve treatments of the diseased brain. We build personalised brain models based on theories of network science and complex systems and apply these to real-world problems in neuroscience and medicine such as epilepsy and aging. The novel neurotechnologies establish workflows and solutions in EBRAINS, translated to clinics and adopted by industry partners.
How we are organised
To achieve the proposed objectives and produce the Showcases, the WP1 Work Plan is composed of 16 Tasks in which 37 Partners are contributing. These Tasks interact with each other as well as with other Tasks from the science WPs and from the infrastructure WPs. The activities proposed in these Tasks will release 46 Outputs associated to 6 Deliverables.
