  • Located in the occipital regions bilaterally as positive waves.
  • Triangular in shape (like the capital lambda: Λ) and generally symmetric.
  • Amplitude: 50 microV
  • Duration 200-300 msec
  • Present with eyes opened and during visual fixation
  • Same morphology as POSTS (Positive occipital sharp transients of sleep), both in form and in occipital distribution, however POSTS are during sleep.
