Wicket spikes

  • Short runs of 6-11Hz spikes, sometimes single spike
    • usually within alpha frequency range
  • Monophasic arciform waveforms (60-200uV)
  • Anterior or mid-temporal region
    • Usually present unilaterally with shifting emphasis between sides
  • Sharp monophasic, no slow wave
  • Present in relaxed wakefulness, drowsiness, light sleep
  • Usually in middle and late adulthood

  • Clinical significance: analogue of the auditory alpha rhythm
