B01 | Toward virtual deep brain stimulation

Deep brain stimulation (DBS) is experiencing a paradigm shift away from studying localized therapeutic effects toward the impact of DBS on distributed brain networks. By combining a connectomic DBS approach with global brain simulations, we will explore networks that – if modulated – lead to a reduction in specific symptoms and add a mechanistic dimension to the concept by modeling their network dynamics.

Within B01, Nanditha Rajamani is pursuing her PhD in the Horn laboratory, while Jil Meier is pursuing a postdoc in the Ritter laboratory.

Both the Ritter and Horn laboratories develop widely used open-source software applications for whole-brain dynamical brain simulation (The Virtual Brain) and DBS electrode localizations (Lead-DBS) which will be applied and further developed in the project.

Within Lead-DBS development, the Horn laboratory could establish an array of novel methods, including DBS network mappingSubcortical Electrophysiology Mapping and probabilistic conversions of stereotactical coordinates to standard neuroimaging (“MNI”) space.

Further information about the two PIs can be found on the respective lab websites:

A main goal is to model how DBS retunes static and dynamic networks which are involved in specific symptoms. For the future, we envision a symptom-specific treatment strategy that may lead to personalized medicine in DBS and neuromodulation as a whole.

Further open data sharing applications developed by the Ritter lab includes participation within the EBRAINS platform. The EBRAINS research infrastructure is the entry point for researchers to discover EBRAINS services. The services are being developed and powered by the EU-funded Human Brain Project.

Finally, a specific interest of the Horn laboratory is to develop normative connectomes of the human connectome and to curate atlases of the human brain:
