Electroencephalography

Electroencephalography. The field generated by a patch of cortex can be modeled as a single equivalent dipolar current source with some orientation (assumed to be perpendicular to cortical surface). Duracell. Electroencephalography.

The Event-Related Potential (ERP)

The Event-Related Potential (ERP). Embedded in the EEG signal is the small electrical response due to specific events such as stimulus or task onsets, motor actions, etc. The Event-Related Potential (ERP).
