Computational Neuroimaging Group (CNG)

Head of the computational neuroimaging group (CNG):

  • Professor Peter Bede

The Computational Neuroimaging Group (CNG) is a large translational research laboratory led by Professor Peter Bede. The CNG is a multidisciplinary lab consisting of neurologists, mathematicians, psychiatrists, psychologists, ophthalmologists, post-doctoral researchers, PhD and MSc students with a shared interest in linking clinical phenomena to structural and functional brain alterations.

The group has been successful in describing phenotype- and genotype-associated imaging signatures and mapping longitudinal trajectories across several time-points from the presymptomatic phase of various disorders to the final stages of neurodegenerative conditions. With a strong emphasis on clinically relevant research questions, the CNG applies a variety of cutting-edge neuroimaging methods to identify, track and characterise disease propagation patterns in vivo. The group’s main interest is Amyotrophic Lateral Sclerosis and Frontotemporal dementia, but they have conducted successful studies in HIV encephalopathy, epilepsy, multiple sclerosis, primary lateral sclerosis, myotonic dystrophy and spinocerebellar ataxia. Professor Bede holds a number of prestigious research grants from a variety national and international funding agencies and the CNG is a contributing member of several international consortia such as ENCALS, TRICALS, NISALS, and Precision ALS.  

The CNG formally publishes its novel research findings in peer-reviewed scientific journals, but also promptly shares their observations with patient charities, advocacy groups, scientific collaborators and industry partners. In addition to pursuing academic research studies, the main mission of the Computational Neuroimaging Group is to develop viable diagnostic and monitoring protocols to aid individualised patient care and improve pharmaceutical trial designs.
