Dr. Ahlfor’s research focuses on non-invasive neuroimaging — in particular, the analysis and interpretation of magnetoencephalography (MEG) signals. He has developed methodologies for multimodal integration of MEG, electroencephalography (EEG) and structural and functional magnetic resonance imaging (MRI) data. He and colleagues, in the David Cohen MEG Laboratory and elsewhere, are currently using effective connectivity analysis of combined MEG, EEG and MRI data to identify neural mechanisms that regulate phonological structure during human language processing, and MEG and 7T-fMRI to identify feedforward and feedback influences in cortical activation associated with multisensory processing. He also collaborates with clinical and cognitive scientists in applications of MEG to studies of normal as well as various clinical populations, including patients with epilepsy, aphasia, obsessive compulsive disorder, dyslexia and autism.
