 PhD Project In general I am interested in visual processing of natural stimuli. In my PhD project I am decomposing natural images to investigate interaction in the processing of their orientations in primary visual cortex with the method of voltage sensitive dye imaging. I work together with Sascha Rekauzke² and Selim Onat¹ and my PhD supervisors Peter König¹ and Dirk Jancke².
