MEG Faculty
Don Rojas, Ph.D., Director
The magnetoencephalography (MEG) facility is dedicated to research developing new electrophysiological metrics for the assessment of brain function with an emphasis on major mental disorders such as schizophrenia, bipolar disorder and autism. These strategies emphasize the high temporal resolution of MEG, which has millisecond timing precision. This directly contrasts MEG with the other technology available at the Brain Imaging Center, fMRI, which has excellent spatial resolution but generally poor temporal resolution. We also combine MEG with MRI information, overlaying the MEG functional results onto anatomical MRI scan data (termed magnetic source imaging: MSI). Recent efforts also include combining the strengths of MEG and fMRI: the high temporal resolution of MEG combined with the high spatial resolution of fMRI can potentially provide complementary information when both types of scans are completed on the same research subject.
The MEG facility, or Colorado Neuromagnetic Imaging Center (CNIC), operates a 248 channel neuromagnetometer system (Magnes WH3600, 4DNeuroimaging, Inc.) and has the capacity to record up to 64 additional channels of EEG, EKG, EOG or other electrophysiological signals. Stimuli can be delivered in auditory, visual and somatosensory modalities and subject responses may be recorded in a variety of ways. An MEG compatible limbus-tracker is also available for eye-tracking experiments.
The MEG facility, like the MRI scanner, is available as a fee for service. Basic service includes preparatory time and scan time and is billed on a per patient per hour schedule, similar to the 3T MRI. Laboratory staff can provide assistance with experimental design and/or data analysis for an additional fee. MEG physics expertise is available within the laboratory to assist investigators with study design and analysis needs.
