Connecting the dots to unlock brain structure

A review of recent developments in statistical methods has highlighted the breadth and difficulty of challenges preventing new insights from neuroimaging data, with the ultimate goal a more comprehensive model of brain structure and function.

The human brain is a major focus of research, with scientists relying on statistical methods to draw conclusions from neuroimaging studies. Yet much about the brain’s structure and function is still poorly understood.

The emerging field of connectome genetics, which seeks to identify the genetic factors that influence brain connectivity, may shed light on cognitive functions and high-level brain activities, such as memory retrieval and decision making, as well as the diagnosis and treatment of neurological and mental diseases.

This led Hernando Ombao from KAUST, in collaboration with Dustin Pluta and Zhaoxia Yu from the University of California, in the United States, and researchers in China, to conduct a review of current statistical methods used in connectome genetics with a view to identifying new and improved approaches for analysing and interpreting imaging genetics data.

“Higher-level cognitive functions depend on the interaction and transfer of information between many localized regions of the brain, so there is a need to study the potential role genetics plays in brain function, and in particular in brain connectivity,” explains Ombao.
