Sensorimotor Cortex Reorganization in Alzheimer's Disease and Metal Dysfunction: A MEG Study

Figure 1

SEF and M20 and M30 ECD positions in a representative healthy control (F, 68 y.o., MMSE = 29) and an AD patient (F, 63 y.o., MMSE = 24). (Top) superimposition of all channels in the rolandic region, averaged in the [−20, 100] ms period, 0 representing the time of stimulus delivery. The amplitude of the magnetic field is represented in femtotesla (fT) on the -axis; (Bottom) positions of the ECDs explaining the cerebral activation in correspondence to the M20 (black circle) and M30 (white circle) components, projected onto a suitable axial slice after volumetric head reconstruction from individual MR images.
