From: Testing covariance models for MEG source reconstruction of hippocampal activity
Reconstructed theta band power based on hippocampal only (left panel) and whole-brain (right panel) correlated priors contrasted (paired T-test) against the uncorrelated source model. Left: Comparing uncorrelated to a model containing a correlated hippocampus, we noted a significant increase in theta-band (4–8 Hz) power over the anterior hippocampal areas. Right: Contrasting the whole-brain correlated model with the uncorrelated EBB solution. We observed bilateral anterior hippocampal clusters with significant increases in power in the parahippocampal, rhinal and temporal pole areas. Results have been tranformed into MNI space for visualisation purposes.
