- 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.
