Electrophysiology. Electroencephalography Electrical potential is usually measured at many sites on the head surface More is sometimes better.
Subdural Grid Intracranial electrodes typically cannot be used in human studies It is possible to record from the cortical surface Subdural grid on surface.
Electroencephalography The field generated by a patch of cortex can be modeled as a single equivalent dipolar current source with some orientation (assumed.
Electroencephalography and the Event-Related Potential Time Voltage -Place an electrode on the scalp and another one somewhere else on the body -Amplify.
Brain Electrical Source Analysis This is most likely location of dipole Project “Forward Solution” Compare to actual data.
