A magnetoencephalography spatiotemporal analysis of neural activities during feature binding.
Previous literature shows that feature binding processes elicit fronto-hippocampal areas. The time course of this process, however, remains unknown. This is the first study that investigates feature binding using magnetoencephalography. Synthetic aperture magnetometry analysis was used to localize sources of increased power in the theta band during the encoding phases of a feature-binding task in the left and right medial frontal gyri (Brodmann's area 10) and left and right anterior cingulate gyri. Theta band synchronization was observed in many of these same areas, but also in other areas not noted to have increased theta band power suggesting a broad network of regions subserving the encoding phase of feature binding.
