TMS-fMRI RESEARCH · MEDICAL UNIVERSITY OF VIENNA

Neuroimaging-informed
brain stimulation.

We combine brain imaging with precisely timed stimulation to understand how human brain networks respond — and to inform more personalised approaches to neuromodulation.

TMS-fMRI research in Vienna.

Led by Martin Tik, our group brings together medical physics, cognitive neuroscience and translational research. Our central tool is interleaved TMS-fMRI: stimulation provides the intervention; imaging reveals the network response.

We investigate where, how strongly and when to stimulate. Our work spans individual target engagement, language and working memory, with collaborations connecting Vienna to Stanford, Hong Kong and Toronto.

Connectivity. Intervention. Timing.

The same brain network can be studied in different ways. Explore how observation, intervention and timing reveal different aspects of a network.

Observe. Perturb. Time.Brain regions fluctuate together. A targeted perturbation tests network responses. Task-relative timing adds another experimental dimension.

01 / OBSERVE

Functional connectivity

Which regions fluctuate together? Correlated BOLD signals provide a network hypothesis.

02 / PERTURB

TMS-fMRI mapping

What changes when we stimulate a region? We measure the local and remote BOLD response.

03 / TIME

Chronometric TMS-fMRI

Does the response depend on when we intervene? Pulses are timed to specific task phases.

TMS gives us temporal precision in the intervention. The fMRI readout remains a slower, indirect haemodynamic signal.

Research directions

02

Chronometric TMS-fMRI

Test how the timing of a pulse relative to a cognitive task changes network engagement.

04

Language and cognition

Connect stimulation-induced changes in behaviour with responses in language and working-memory networks.
