Tripolar concentric EEG electrodes reduce noise.

CONCLUSIONS: TCRE produced similar overall quality and confidence ratings versus regular electrodes, but less muscle artifact. TCRE recordings detected seizures in 7% of instances where regular electrodes did not.
SIGNIFICANCE: The combination of the two types increased detection of epileptiform events compared to either alone.
