Semi-blind deconvolution of neural impulse response in fMRI using a Gibbs sampling method

by Salima Makni, Jérôme Idier, Jean-baptiste Poline - in [Proc. IEEE Int. Conf. Acoust., Speech, and Signal (ICASSP , 2004
"... In functional Magnetic Resonance Imaging (fMRI), the Hemodynamic Response Function (HRF) represents the impulse response of the neurovascular system. Its identification is essential for a better understanding of cerebral activity since it provides a typical time course of the response to a stimulus ..."

be characterized by a single HRF but varying magnitude in space. Our goal is to estimate those magnitudes that could then be interpreted as a correlate of the neural response. We are thus faced with a semi-blind deconvolution inverse problem since the time arrivals of the neural response are known: they correspond
