Alpha waves are psionic emanations produced by psionic terrans such as ghosts when they are using psionics.[1] Psionics can recognize other psionics through their alpha waves. While they can track the area of a fellow psionic by their alpha waves, they do not allow them to pinpoint their exact location.[2]

Zerg can detect ghost psionic emanations,[3] although this fact was relatively unknown among the general civilian populace prior to the invasion of Maltair IV.[4] Due in part to a Terran Dominion propaganda campaign, this became common knowledge during the hunt for Colin Phash.[5] Black widows are able to detect alpha patterns, swarm a target area, and explode.[2]
