The human brain has a multi-level organisation and high complexity. New approaches are necessary to decode the brain with its 86 billion nerve cells, which form extensive networks. Ultra-high resolution models of the brain pose massive challenges in terms of data processing, visualisation and analysis. The Human Brain Project creates a cutting-edge European infrastructure to enable cloud-based collaboration among researchers from different disciplines around the world. The infrastructure includes development platforms with databases, workflow systems, petabyte storage. New technologies, including neuromorphic computing and robotics are being developed. Neuroscientists and ICT-specialists collaborate in a co-design process, based on neuroscientific use cases, to develop such infrastructure, thus opening new perspective to decode the human brain.
The human brain has a highly complex, multi-level
organisation. New approaches are necessary to decode
the brain with its 86 billion nerve cells, which form
complex networks – a challenge that is addressed by
the Human Brain Project (
High-resolution data obtained in post-mortem brains supplement information about structural and functional connectivity as obtained, e.g., by Magnetic Resonance imaging, acquired from the living human brain, but with lower spatial resolution. By bringing together different aspects of connectivity in one and the same atlas, it is feasible to combine the advantages of the different approaches, and to address the different spatial (and temporal) scales.
The Human Brain Project is developing a new
European research infrastructure. Part of it is the HBP
atlas. It integrates information from multiple levels of
brain organisation including cellular architecture,
connectivity, molecular and genetic maps, as well
results from neuroimaging and physiological studies.
This atlas is a resource for empirical research, but also
modeling and simulation. To represent microscopical
data, it includes the Big Brain as one of its templates

The HBP infrastructure will enable cloud-based collaboration among researchers coming from different disciplines around the world. To achieve this, research platforms include databases, workflow systems, petabyte storage, and supercomputers, to address the requirements of the different users.
The core project involves 117 institutions and 500 researchers from 19 countries. It is organized in 12 Subprojects. Neuroscience Subprojects include: Mouse Brain Organization, Human Brain Organization, Systems and Cognitive Neuroscience and Theoretical Neuroscience. Activities in these Subprojects provide insights across all levels of brain organization: They will be more and more linked and integrated into comprehensive models, and tested by simulation.
Big data analytics and simulation are highly
challenging and data intensive. Therefore, the Human
Brain Project embraces ICT solutions. These include
cloud-based collaboration and development platforms,
with databases for metadata and provenance tracking,
as well as data analytics and compute services, right up
to leading-edge supercomputers, neuromorphic
systems (
The main IT service infrastructures is represented
by the Neuroinformatics Platform (NIP) and the
HighPerformance Analytics and Computing Platform
(HPAC). Data from patients are being collected and
analysed in the Medical Informatics Platform (
The development of the platforms is guided by codesign projects where neuroscientific investigators and IT specialists collaborate. After the Ramp-up phase of the HBP from 2013 to 2016, the platforms were released in March 2016, can be accessed by test-users: https://www.humanbrainproject.eu/en/.
The NIP is conceptualized in such a way, that
researchers from other countries can share their data,
tools and expertise, to decode the human brain. This
includes also collaboration with other brain initiatives

To obtain the means needed to address the incredible complexity of the brain, the neuroscience community will need to become a competitive player on high-end supercomputers and systems for big-data analytics. The HPAC aims to provide the Human Brain Project and in extension the neuroscience community with High Performance Computing systems geared towards the particular needs of neuroscientists.
Four European Tier 0 supercomputer centers currently are members of the consortium of the HBP: the Barcelona Supercomputing Centre (BSC) in Spain, the Consorzio Interuniversitario per le Applicazioni di Supercalcolo per Università e Ricerca (CINECA) in Italy, the Centro Svizzero di Calcolo Scientifico (CSCS) in Lugano, Switzerland, and the Jülich Supercomputing Centre (JSC) in Germany.
At the JSC, two new pilot systems for an interactive supercomputer have been obtained as the result of the “Pre-Commercial Procurement”: JULIA, developed by Cray, and JURON from IBM and NVIDIA. These systems are specifically designed for data-intensive analytics and simulation applications in the neurosciences.
The convergence of neuroscience and ICT that the Human Brain Project envisions in the long run depends on training a new generation of young researchers to be fluent in both areas. To this end, the HBP Education Programme offers online courses, advanced HBP Schools, an annual HBP Student Conference and Young Researchers Events.
