Language-training induced changes of peak frequencies in stroke patients with aphasia

Are the peaks of the EEG spectrum changed upon a BCI-supported language rehabilitation training?


Left-hemispheric stroke can lead to different language deficits, which are a heavy burden both, for the individual and his/her social interaction, as well as for society. While spontaneous recovery in the first weeks after the stroke may reduce this so-called aphasia, many patients remain with different language problems also in the chronic phase. The rehabilitation of these stroke-induced language deficits can be brought forward in chronic patients with a novel BCI-based training approach developed in our research group. The training so far has been tested successfully in a pilot trial (see

Research question

To better understand the underlying mechanisms of the observed training success, we would like to investigate the following question:

Which changes EEG spectral peaks relate to successful language training with the novel BCI-based approach?

Skills required:

  • BCI background by accomplished course SOW-BKI 323 or SOW-MKI 74
  • Good programming skills in Python (familiarity with numpy, sklearn, at least one popular deep learning framework).
  • Good mathematical background and intuition.
  • Machine learning background
