Get access to the state-of-the-art facilities and resources of HBP Partner institutions, to foster collaboration and carry out cutting-edge scientific research.
HBP and HBP Partners provide access to three types of Facility Hubs:
- Physical facilities (e.g. microscopes)
- Competence centres providing specialised software support going beyond the EBRAINS High Level Support Team
- The European Institute for Theoretical Neuroscience (EITN)
Facility Hubs are aligned with the Fenix supercomputing network to provide user access to computing resources, e.g. for data storage, analysis, and simulation.
The Facility Hubs are contributions from HBP Partners to the new EBRAINS research infrastructure, and complement the EBRAINS services currently on offer.
Users from academia and industry world-wide are eligible to apply for access to HBP Facility Hubs.
Interested users of the Facility Hubs are asked to contact the respective Facility Hub contact for a first discussion on the potential project and support as well as the feasibility. Users must bring their own funding for the project which goes beyond the offer/support by the Facility Hub. Facility Hub support can also be included in applications to Calls.
Users are asked to submit a short project description to the Facility Hub contact using the template provided by the Facility Hub contact, which includes a project summary, complementarities and synergies with the Human Brain project, and the expected outputs. Since most of the Facility Hubs require extensive compute resources (e.g. for simulations or data storage), the Facility Hubs are aligned with the Fenix research infrastructure. Facility Hubs have applied via ICEI (Interactive Computing E-Infrastructure for the Human Brain Project) for a certain amount of compute and data, resources which they can make available via "wide access" to users of the hub. If users would need more resources than supplied at the Hubs, they would have to submit a request via ICEI.
The respective Facility Hub decides which projects are supported according to its rules and regulations. Criteria for the selection are scientific excellence, impact and contribution to the aims of the Human Brain Project, EBRAINS and the Facility Hub, as well as ethical compliance with the regulations of the Hub.
Users are asked to deliver a short project report by the end of the project according to the template which will be provided by the Facility Hub contact before the project starts.
To monitor the interest and usage of the Facility Hubs by the community, user requests and outcomes of supported projects are documented and analysed on a yearly basis. This information is only for internal use. Collected data is GDPR compliant.
Two-photon imaging and ensemble recordings, both conducted in behaving, task-performing animal models, are illuminating our understanding of how cognitive, perceptual and motor functions originate from the behaviour of large, cooperating populations of neurons. The University of Amsterdam (UvA) facility hub and competence centre offers access to a Leica fast resonant two-photon scanner and high-density ensemble recording setups using Neuropixels and other silicon probe configurations. The core expertise in electrophysiological, optical and behavioural recordings is supplemented by opto- and chemogenetics, large-scale data analysis centred on population decoding and computational modelling.
The UvA can host medium (2-6 mo.) or longer (>6 mo.) term projects for PhD students, postdocs and research staff who need to acquire multiple technical skills and/or want to acquire data for a project. Shorter or remote visits are possible for researchers wanting to learn individual skills related to data-analysis. Organising online and on-site courses and webinars for large groups is also possible.
The UvA harbours one of the largest groups for two-photon in vivo neuronal imaging and ensemble recordings in Europe, which is uniquely distinguished by its development of sophisticated behavioural paradigms testing multisensory perception, memory and consciousness, a high level of multidisciplinary integration and technical versatility.

The hub “3D-Polarised Light Imaging” at the Institute of Neuroscience and Medicine (INM-1), Forschungszentrum Jülich, Germany, offers hands-on insights into the research of the brain’s fibre architecture at microscopic scales, based on unstained histological brain sections.
The imaging technique of choice is referred to as 3D-Polarised Light Imaging (3D-PLI) and has been uniquely developed at the INM-1 over the last ten years. It basically utilises the optical birefringence of nervous tissue, mainly induced by myelinated axons. 3D-PLI makes studies of the fibre architecture (e.g. identification and tracing of fibre pathways and tracts, and quantification of fibre orientations and myelin distributions) in 50μm thick brain sections possible.
The hub offers possibilities
(i) for initial consultation about the topic of fibre-targeted microscopy,
(ii) to carry out a feasibility study, or
(iii) to obtain independent cross-validation on a small scale
for three weeks per year.
An approved project exclusively includes introductory training and guidance in brain cryo-sectioning and tissue mounting specifically required for 3D-PLI applications. Section scanning will be closely supervised by an on-site expert and carried out using one of the available polarising microscopes. Finally, comprehensive image analysis will be performed utilising the FENIX infrastructure, including high-performance computing, data storage and sharing resources at the nearby Jülich Supercomputing Centre.

The combination of focused ion beam (FIB) milling and scanning electron microscopy (SEM) is a method that permits the rapid and automatic serial reconstruction of large tissue volumes. The FIB/SEM facility —located at the Centro de Tecnología Biomédica (Laboratorio Cajal de Circuitos Corticales, UPM/CSIC), Universidad Politécnica de Madrid )— is intended to be a leading center for (i) detailed synapse studies using 3D electron microscopy and (ii) generation of high-resolution images of brain regions in the millimeter to nanometer range.
For detailed information see ‘FIB/SEM: Description and applications to study the brain’ at http://cajalbbp.es/CBB
This FIB/SEM facility is associated with high-level scientific and technician staff who will provide the necessary expertise in electron microscopy to ensure that any scientist can benefit from this facility, regardless of whether or not they have experience in electron microscopy. The profiles involved in the projects will be Senior Researchers, High-Level Technicians and Laboratory Technicians. The number of people involved will be based on the project needs, with this experienced staff devoting 20% of their time to supporting the selected projects.
The UPM can host medium (2–6 mo.) or longer (>6 mo.) term projects for PhD students, postdocs and research staff who need to acquire multiple technical skills and/or want to acquire data for a project.
Light-Sheet Fluorescence Microscopy (LSFM) of cleared brain samples offers the unique opportunity of exploring brain complexity on large scales yet at cellular resolution. The European Laboratory for Non-Linear Spectroscopy (LENS) has gathered long-standing experience in the whole LSFM pipeline, comprising sample preparation (clearing and staining), the actual imaging using custom-designed optical setups, and image post-processing (volumetric stitching, compression, feature segmentation). The LENS facility hub offers access to two microscopy setups capable of high-speed and high-resolution imaging with simultaneous two-colour acquisition. One system can accommodate large bulky samples such as a whole mouse brain, while the other microscope is designed for thin but large tissue slices (several cm in lateral size, 0.5mm to 1mm in thickness).
Within the facility hub, LENS can provide the full service (clearing, imaging and processing) or can host external scientists that wish to use the microscopes or acquire technical skills in light-sheet microscopy. Specific projects need to be discussed beforehand to ensure an optimal planning of resource usage and the organisation of specific training if needed.
LENS is an interdisciplinary international laboratory doing research in the field of biophotonics, photonic materials, and quantum technologies. It is home to a PhD school and offers the International Doctorate in Atomic and Molecular Photonics through the University of Florence.

The HUB is based in UNIPV and performs multiscale modelling spanning from neurons and microcircuits to large-scale networks and the whole brain. The HUB leverages on the unique concept of the Brain Scaffold Builder (BSB), a modelling workflow that allows multiscale modeling of neurons, microcircuits, large-scale networks and whole brains.
Although initially designed for the cerebellum, BSB can be easily applied to any brain networks through customised developments on demand. The BSB supports different modelling platforms and formats and can be applied to neuromorphic hardware, robotic control systems and virtual brain simulators. A special aspect of the HUB is to provide the infrastructure and expertise for multiscale experimental validation of the models in rodents. The HUB is relying on EBRAINS and shares with it a set of highly integrated APIs and several sophisticated model building tools.
Dedicated community managers will help users through any issue they may have in exploiting the HUB, in arranging the specific development workflows and simulation of interest, or to help in getting the appropriate HPC allocation for the project. In summary, the HUB will allow researchers and customers with different interests, background, and expertise to develop their own computational models and transform them into different kinds of applications. Dedicated tutorials and community managers will guide users through all the steps needed to reach their specific goals.
The highest impact of this unique installation is expected on engineering and medicine, especially concerning brain-inspired technologies and the investigation and cure of brain diseases.

The Hippocampus Hub is a Reference and Community Web Portal for scientists, students, and interested users to explore data and use, or implement, models related to the hippocampus.
In the Reference Model section, biophysically detailed models of neurons, synapses and a hippocampal microcircuit are featured. The hippocampus CA1 will follow in 2022. This section allows the user to review the models in detail, explore the underlying data and execute models in in silico experiments, using high performance computing infrastructure provided by the HBP EBRAINS infrastructure.
In the Community Model section, an interoperable database of hippocampal related data, such as morphologies or electrophysiological traces are fetched from public resources and a modelling portal for single cell and circuit in silico experiments is provided.
The Hippocampus Hub is a unique facility and we expect to have a big impact on the consolidation and reach of dissemination for hippocampus research, helping to increase the community uptake.

The Basal Ganglia Modeling Center in Stockholm is co-hosted at the Royal Institute of Technology (KTH) and Karolinska Institute (KI). This modelling Hub facilitates modelling and simulations of the basal ganglia, using a data-driven approach. Modelling is performed at multiple scales, from the molecular, detailed neuron and microcircuit-level, to large scale brain networks and behaviour, where both function and dynamics can be linked between the scales and investigated.
Emphasis is on allowing the user to set up new or use pre-defined virtual experiments to investigate the basal ganglia and related structures. These virtual experiments can then be directly compared to, or verified by, animal experiments. As the models are refined and allow a test of putative mechanisms for learning and selection of behaviour, this will lead to new insights and reduce the number of animals needed for experiments.
The Hub is relying on EBRAINS tools and workflows. For example, a software framework, Snudda, can be used to automatically set up a microcircuit model using detailed morphologically reconstructed neuron models, which is then currently simulated using NEURON on either local machines or on supercomputers for the large networks. Also, a toolset for the simulations of subcellular signalling processes, involved for instance in learning is provided.
Community managers will help users to use and collaborate using the EBRAINS tools and workflows useful for understanding the basal ganglia in health and disease. In addition, some guidance in getting the appropriate HPC allocation for the project will be provided. In summary, the Hub aims at facilitating, for researchers with computational, biological or medical backgrounds and areas of expertise, collaborations around questions regarding basal ganglia function. Tutorials will be provided when needed. Our aim is to create a multidisciplinary community, where scientists help each other, and share their new findings and ideas, forming new collaborations. We will also actively develop open source tools and improve our modelling pipeline.
The highest impact of the Basal Ganglia Modeling Center will likely be on basic science, engineering and medicine, the latter with regards to the many neurological and psychiatric diseases that affect the basal ganglia such as Parkinson’s disease.
NEST is a simulator for spiking neural network models based on over 25 years of development that focuses on the dynamics and structure of neural systems, rather than the exact morphology of individual neurons. It is ideal for networks of any size including models of information processing (e.g. in the visual or auditory cortex of mammals), models of network activity dynamics (e.g. laminar cortical networks or balanced random networks) and models of learning and plasticity.
In addition to advanced neuroscientific research, NEST can also be used in education and teaching (NEST Desktop) and as a reference implementation to validate neuromorphic systems.
The NEST Facility Hub, operated by the Forschungszentrum Jülich GmbH, Germany, represents an organizational point of contact that can be approached both from the NEST user and developer side, as well as from the infrastructure side. The Hub offers an up-to-date simulation engine on the level of neurons and synapses provided via Jupyter notebooks on EBRAINS with connection to High Performance Computing (HPC). Additionally it supports users, developers and infrastructure operators in making workflows possible, sustainable and maintainable, acting as a central point bridging between these different views. Users and developers additionally will be provided with software packages for common distributions, as well as containerized solutions such as Docker containers and VM images.
The NEST support helps users of the simulation engine with the installation and handling of the tool and developers in enhancing the openly available community code. For this purposes, a mailing list, an EBRAINS ticketing system, a fortnightly open NEST developers video conference, a Github issue tracker for the coordination of activities, and code reviews have been set up (see https://www.nest-simulator.org/community/). User and developer engagement is supported by user-level documentation, developer documentation and maintenance, and operations documentation (see https://nest-simulator.readthedocs.io/en/v3.3/).
