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!

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

    21

    Jun

    Toronto, Canada

    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.

    The Brain Connectivity Workshop is conveniently right before OHBM in Montreal, Canada (June 26-30).

    Registration

    Tickets for this workshops are limited. You can buy tickets for $350 CAD online.

  • The Virtual Brain at the Human Brain Project Summit

    3

    Feb

    Athens, Greece

    Meet the TVB team at the Human Brain Project Summit & Open Day in Athens from February 3 to 6!

    We will present at the "Explore the Brain" EBRAINS booth on Open day, February 3rd and have a dedicated TVB session on February 5th. Find out about all the TVB tools and services that we made available via EBRAINS!

    HBP is at a crossroads itself, entering its last phase of funding as a FET Flagship project and envisioning its long-term future as a landmark infrastructure in the ESFRI Roadmap. Athens is, thus, a fitting stage for fertile discussions, intense exchange of ideas, and bold new conceptions on the science, infrastructure, research, technology, application, education, and innovation dimensions of neuroscience in general and the Human Brain Project in particular.

  • The Virtual Brain training course at Bernstein Center for Computational Neuroscience Berlin

    3

    Dec

    Berlin, Germany

    Hands-on TVB training course for those of you in Berlin

    We are pleased to announce that we will be holding a training course for The Virtual Brain at the Bernstein Center for Computational Neuroscience Berlin on December 3rd, 2019. The course is intended for students of the Bernstein Center, however if you are not a student there but are interested in joining please contact petra.ritter@charite.de.

    During the course, we will introduce the The Virtual Brain (TVB) - a large-scale simulation platform, from both a theoretical and practical application perspective. This simulation environment allows biologically realistic modeling of the network dynamics of the human brain using connectome-based approaches across different brain scales. This computational modeling system is tailored to the individual, and bridges multiple scales.

    We will be taking a close look at how to operate the TVB graphical user interface, and also the scriptable user interface. During this course you will learn to create your first virtual brain.

    We will also go into details of a clinical application for simulating and predicting epilepsy to inform surgical interventions, and a tutorial on how to run a multi-scale simulation that bridges TVB and NEST.

    We hope you enjoy the program we have put together this year, for more details, please see below:
