Workshop size is limited to 35 attendees and currently we are booked out!
We will serve refreshments during the coffee breaks. Lunch is on your own.
Get up to speed about the fundamental principles of full brain network modeling using the open-source neuroinformatics platform The Virtual Brain (TVB).
TVB enables biologically realistic modeling of network dynamics using Connectome-based approaches across different brain scales.
Generate macroscopic neuroimaging signals including fMRI, intracranial and stereotactic EEG, surface EEG and MEG for single subjects.
Researchers from different backgrounds can benefit from an integrative software platform including a supporting framework for data management (generation, organization, storage, integration and sharing) and a simulation core written in Python.
The architecture of TVB supports interaction with MATLAB packages, e.g. the well-known Brain Connectivity Toolbox.
After the workshop you should have a basic picture of how these models are built, how they work, and what biological properties of a neural system they represent. In addition, we will highlight several research topics that can be explored using this tool.
For the brave ones who like diving directly into the code, we expect you to know some Python, MATLAB, Octave, or whatever programming language you like the most.
The workshop is organized with interleaved oral presentation and hands-on sessions. Attendants will have the time to ask questions.
The hands-on sessions will let you immediately apply the concepts from the lectures to your simulations in TVB.
TVB#Node1 will take place back to back with two important neuroscience conferences, also in Hamburg, Germany:
Scientists from the TVB team are already confirmed speakers for various sessions there.
To get the most out of this workshop as an attendee, you might want to get a head-start by preparing your gear before you arrive:
Apart from learning together, you can meet and talk to a good part of The Virtual Brain's core team, covering a broad range of topics from cutting-edge neuroscience research to advanced software development.
09:00 - 09:15 am
Can I please get a coffee first?
A caffeinated history of The Virtual Brain
09:15 - 10:00 am
A generative model of the brain: Describing the building blocks of a brain network model
Learn about the basic principles and assumptions underlying a brain network model, recent studies using different local models, cortical connectivity and dynamical units. Understand how to approximate neural fields.
10:00 - 10:30 am
Interacting with TVB
Follow the presenters with your own laptop, learning about the web UI as well as the command line and scripting interfaces using Python and MatLab.
10:30 - 11:00 am
11:00 - 11:30 am
How to obtain a TVB friendly dataset
Understand how a complete TVB dataset works, which neuroimaging data formats can be imported and how to set up data-obtaining pipelines extracting subject-specific structural data.
11:30 - 12:30 am
Hands-on: Build your own brain network
Follow the presenters and build your own model, running a host of simulations against it: region-based, local dynamics, parameter space exploration, obtaining functional data like fMRI or EEG, differential simulation analysis with and without noise, surface-based and local connectivity structures
