Abstract

Functional Magnetic Resonance Imaging (fMRI) is a brain imaging modality which gives insight into the way the brain works. It is non-invasive, safe and relatively cheap. However, because of a lot of noise in the data, the results from fMRI studies depend heavily on the employed software and on the many assumptions made by the user in the analysis pipelines. Because of several recent validation studies showing low robustness of some of the fMRI methods, the entire fMRI field came under fire. My work is on validating the existing methods and possibly improving them. In the talk I will speak about fMRI research, as well as about validation studies in neuroimaging and in biomedical research generally. At last, I will present some of my current results related (1) to the modelling of the experimental design and (2) to the modelling of the blood flows in brain in time.
