Pattern recognition and image analysis in brain imaging

As three or four dimensional (3-D, 3-D + time) imaging is the only technique to quantify the brain structure and function in living humans at the system level, analyzing brain imaging data has a unique position within neuroscience. Rapid advances in non-invasive neuroimaging methods have increased the possibilities to study changes occurring in human brain across a variety of time-scales ranging from seconds to entire life span. A large part of these advances can be attributed to the development of dedicated computational algorithms and applied mathematics, which are essential to extract quantitative information from images. Our team develops these computational methods to analyze the brain imaging data, evaluates the methods, for example, by using advanced simulations, and openly distributes the programs implementing the methods.

Current projects:

New neuroinformatics methods for automatic analysis of brain images (active 2009 - 2014, funded by Academy of Finland, PI J Tohka)
This project aims at developing automatic methods for the analysis of brain images. This research belongs to the general field of neuroinformatics. Neuroinformatics combines neuroscience and informatics research to develop and apply advanced tools and approaches essential for a major advancement in understanding the structure and function of the brain. The interpretation of world-wide research data would not be possible without new and powerful computational data analysis approaches. The brain research is essential for the treatment of brain disorders and in future also for the prevention of them. The primary goal of neuroinformatics and related brain research is to investigate how a healthy brain functions. Then, by using this knowledge, it will be possible to study disease processes for instance by means of computer simulations.
