My Virtual Dream at Nuit Blanche 2012
View large version

Brain simulation helps us understanding how our brain works – and developing personalized therapies for its diseases.

A human brain consists of 86 billion neurons and 150 trillion connections between them. It runs on as little energy as an LED light bulb. It would take 1,500 Google data centers (they only have 15) to simulate just one brain with molecular accuracy, costing 1 trillion dollar per year and consuming 600 terawatt hours.

Here at the Brain Simulation Section (part of Charité Universitätsmedizin Berlin), we have been at the forefront of network-based brain simulation, computational neuroscience and its clinical application for more than 10 years.

In collaboration with other international research centers, we have developed a way to simulate a brain even on a laptop – with reduced complexity but feasible, sufficiently accurate, scalable and already used in practical clinical applications.

We work towards our vision of providing digital copies of a person’s brain to virtually plan and test personalized treatment of brain orders, e.g. Alzheimer’s, stroke, epilepsy or tumors.

Our team is growing fast and we would be happy to welcome you, e.g. as software developer, lab manager or research assistant! Check out our current job openings or send us your speculative application!

  • Lab Meeting

    Interview with Dr. Petra Ritter on RBB, listen in the next 7 days

    November 13

    Published on the 13th of November this year, Dr. Petra Ritter gives a short and very informative interview about the Brain Simulation Unit at Charité, including topics of brain health, healthy ageing, and learning.

    You can read some choice quotes, or listen to the 6 minute interview here: RBB, for the next 7 days only. It's a limited time, so make sure you hear it before it's gone.

  • Berlin Bundestag Interior

    The Virtual Brain on Exhibition at the Bundestag

    November 8

    The Human Brain Project shows their work at the German Parliament Bundestag. The Virtual Brain is a central part of the exhibition.

    Meet Dr. Petra Ritter during the opening event on Nov 27th. Dr. Ritter will also lead a guided tour through the exhibition on Nov 28. Access to the exhibition is only possible after prior registration via the website.

    This exhibition is in partnership with The Human Brain Project, and includes many beautiful exhibits about the brain. You don't want to miss it!

    More information about the program here.

  • Presentation by Dr. Petra Ritter at the first NIH workshop: attend IRL or online

    October 29

    The Center for Multimodal Neuroimaging is hosting their first Multimodal Neuroimaging Workshop this week, and tomorrow Dr. Petra Ritter will be presenting as part of the lecture series including 14 other speakers.

    For more information about the series and the other speakers, please see the NIH page for the event here.

    To register for the event, please go to this Eventbrite page.

    The presentations will also be streamed online here, for those of you who are not in the USA and can not make it in person.

    This lecture series should be very interesting, as each of the speakers come from a diverse background and will be coving many topics revolving around multimodal imaging, including data collection, analysis, clinical and research purposes, and the future of neuroscience.

    👋Hope to see you there, in person, or on the internet. 🖥️✨

  • Short video of the Brain Atlas in use

    iOS Brain Atlas Beta Test Release

    October 23

    Hey there! 👋

    Our Brain Atlas, a collaborative project with HBP, has been getting a lot of attention lately:

    So, we thought we would release it on iOS. Just click this link to sign up anonymously for the beta program.

    This beta program is only for the first 1000 users, so dont be shy. We have more updates planned, and you will get them automatically via the Apple beta program (TestFlight).

    Also, anyone can view the Brain Atlas WEBGL version, or in the HBP collab platform, in a web browser. [Unfortunately the WEBGL version doesn't work on most mobile due to standard security and performance issues]

    Curious how you all like it. We hope you like it as much as we do. Stay tuned for more updates.

Meet our team

  • Brain Connectivity Workshop 2020 to be held in Toronto, Canada



    Toronto, Canada

    We are excited to announce that Dr. Petra Ritter will talk at the Brain Connectivity Workshop in Toronto in June 2020. Registration for the event will open in January 2020 and until then you can sign up for more info or check out the preliminary program here.

    The aim of Brain Connectivity Workshop is to establish a dialogue between researchers in computational neuroscience, neuroscience methodology and experimental neuroscience about the emerging field of brain connectivity.

    This year the workshop will revisit the first ever Brain Connectivity workshop theme from a different perspective: "What does the mind think of the brain?" – focusing the discussions around what we have learned about our mind over the last 20 years of brain connectomics.

    The topics will deal with consciousness and cognition, looking at the tripartite relationship between anatomical connectivity, brain dynamics and cognitive function.

    Next year's Brain Connectivity Workshop is conveniently before OHBM in Montreal, Canada (June 26-30).

  • The Virtual Brain at Mobile World Congress Barcelona, 2020



    Barcelona, Spain

    We are excited to announce that the The Virtual Brain and Virtual Brain Cloud will have a booth at the Mobile World Congress in Barcelona in February 2020.

    We will be showing our work alongside the Human Brain Project and industry partners Eodyne and Indoc.

    Further details will be announced here, so watch this space!

  • Medical University Charité's 26th Neurokolloquium



    Berlin, Germany

    The 26th Neurokolloquium will be held on the 15th of February at the Charité Campus Virchow Klinikum.

    Neurokolloquium is an annual symposium put on by the Charité Clinic and University Outpatient Department for Neurology, during which a variety of lectures and presentations are held on topics from the entire spectrum of work done in the Neurology Department.

  • Dr. Petra Ritter & Paul Triebkorn present The Virtual Brain at Urania



    Berlin, Germany

    Urania Berlin is one of the leading centers of dialog between science, the humanities and the public. We are excited to join the many leading scientists who deliver lectures and talks in their areas of research at Urania.

    Petra Ritter and Paul Triebkorn will present The Virtual Brain at Urania Berlin on January 21st, 2020.

    The talk will be a part of a series called Berlin Brains 2020, during which neuroscientists working in Berlin will present their current work to the public.

    Join us at Urania to hear about how human brains are simulated using The Virtual Brain simulation platform. We will cover how this platform allows researchers to work together, what role the EU Human Brain Project plays and how digital brain simulations help patients.
