Fundamental Principles for Biological visual Information Processing

The investigation of the fundamental principles for biological visual information processing is a new PhD project at Aarhus University, Health. The project was carried out by Daniel Gramm Kristensen, who is defending his dissertation on 29/08.    

How visual experience arises from neural activity in the brain is still a mystery. Using functional Magnetic Resonance Imaging, we examined the properties of visual population receptive fields, and we discovered a principle that could explain their organisation. This discovery served as the basis for the development of a theoretical framework for biological visual information processing that draws on principles from quantum mechanics, electronic engineering and information theory. We tested some of the predictions of this theoretical framework by designing a psychophysical experiment with visual illusions. It was found that the observed effects were in agreement with the predictions of the theoretical framework, yet more research is required to verify this result and to refine the theoretical framework. The successful establishment of a theory that lays out the fundamental properties of biological information processing holds great potential for application in other perceptual modalities, but also in understanding perceptual disorders.  

The defence is public and takes place on 29/08 at 14:00 in The Merete Barker Auditorium, Aarhus University, Bartholins Allé 3, 8000 Aarhus C.

ALL ARE WELCOME

The title of the project is "Uncertain Principles and Visual Information".
