David Linhardt studied Technical Physics as his Masters at the Technical University Vienna. Already during his studies, he started working in functional MRI and rapidly specialised towards studies on the human visual system. At the High Field MR Centre, together with Allan Hummer, he found the perfect environment researching for his Master Thesis “Stimulus selection in functional magnetic resonance imaging-based retinotopic mapping”. Several peer-reviewed conference abstracts resulted from methodological innovations in the field of pRF mapping. Clinical translation of these methods was achieved by cooperation with the local Ophthalmologic department of the Medical University of Vienna. In these clinical studies, pRF mapping enabled investigating dysfunctional areas on the retina, so–called scotomata in patients suffering from different eye diseases. In the recently published paper “Combining stimulus types for improved coverage in population receptive field mapping” the authors, for the first time systematically assessed the two most-used stimulus patterns for retinotopic mapping. The important finding of the publication is, that stimulus selection introduces a strong bias and has a huge influence on the study outcome.
