- Located in the occipital regions bilaterally as positive waves, during drowsiness/sleep
- Triangular in shape (like the capital lambda: Λ, only upside down) and generally symmetric.
- Most evident in non-REM 1 and non-REM 2
- Same morphology as Lambda waves, both in form and in occipital distribution, however lambda waves are during awake state, when visually fixating.
- POSTS are completely normal, should not be confused with spikes
