-a technique of forced breathing, amplified and/or speeded up, used particularly in bio-energetics, in rebirthing and in holotropic breathing (Grof), and aiming to free up the subcortical layers by 'intoxicating' the cortical control through hyperoxygenation. Freeing up buried emotions often provokes catharsis, which may be accompanied by convulsive movements or spasms. In Gestalt, this kind of artificial technique is not used, but sometimes spontaneous hyperventilation occurs, triggered by intense emotion.
