Wicket spikes

  • Wicket spikes are another waveform that is without pathological significance, occurring almost exclusively in adults. [8]

  • They are thought to be due to harmonics of 2 or more waveforms that combine to form pseudospikes.

  • Like wicket rhythm, they have rounded aspects to 1 side and sharp points to the other, giving the appearance of spikes or sharp waves.

  • When these are especially large, they may appear similar to pathological spikes. However, they generally can be distinguished by their morphology and at times by their defined background rhythms, which are harmonizing.

  • They can be seen either in wakefulness or sleep in the anterior or temporal head regions.
