Analysis of single subject auditory evoked response data with no knowledge of head location. (a) Posterior current density estimate. (b) Confidence intervals on the left and right hemisphere maxima (coloured). The grey ellipsoids indicate the 95% confidence intervals on dipole locations for the subject group. (c) Prior and posterior distributions of the Nasion fiducial (based on MEG data and uniform priors); zero shows the nasion estimate based on co-registation.
