EEG and auditory evoked potentials
●
Periodic patterns: Distinct waveforms
repeating with regular intervals (from
0.5 to several seconds). Periodic
patterns that are characterized by
sharp waves or spikes are known as
epileptiform.
●
Burst suppression: High amplitude
EEG patterns with intervening low
amplitude activity. The duration may
vary from <0.5 seconds to several
seconds.
Technical artifact and EEG
To decrease technical artifact, the electrode-to skin-impedance should be low and
electrode wires short. Wrapping the electrode wires together or adjusting ground
electrodes may also help.
Typical EEG recordings with electrical interference
●
Electrical currents (AC): These are a
common source of interference. Try
using different low-pass or notch filters to
eliminate them.
●
Eye movements: Patient eye movements
cause typical patterns in the EEG
waveform.
