Figure 3.
Hippocampal activation (shown in color) from the sLORETA analysis is plotted on one control participant's (top) and one schizophrenia patient's (bottom) MRI. These images show the most common activation pattern for that group and task. The control showed right hippocampal activation during nonverbal TP and left hippocampal activation during verbal TP. The patient showed left hippocampal activation during nonverbal TP and bilateral hippocampal activation during verbal TP. To the right of the MRIs is the waveform computed from the current density reconstruction (CDR) dipole analysis for that sLORETA region. The vertical red line on the waveform indicates the latency of the hippocampal activation found (shown on the MRI) from the sLORETA results. The last column on the right illustrates each dipoles magnetic field contour map at that same latency. The dots indicate each of the MEG channels, with the top channels located in front of the participant's head and the bottom channels located in back of the participant's head. The red lines illustrates where the magnetic field is exiting the brain and the left lines illustrate where the magnetic field is entering the brain.
