WebJan 26, 2024 · “Triphasic waves” in human EEG are noted as a characteristic GPD with a small upward phase, a large, broad, downward phase, followed by a third larger upward phase ( Figure 8 inset), with a relatively low frequency (0.5–2 Hz). Current human nomenclature describes these waveforms as “GPDs with triphasic morphology” ( 15 ).
