The multiscale imaging group is a multidisciplinary team interested in the application, combination and development of imaging modalities focused in brain at several scales. Our greatest interest is the study of the structure of the healthy and diseased brain from the macro- and microscale with non-invasive techniques to the nanoscale with microscopy techniques in combination with image processing, data analyses and tissue modelling.
