disentrainment

Noun

disentrainment (plural disentrainments)

1. The act or process of falling out of entrainment; precipitation form a flow or current.
   • Subsequent disentrainment relies upon opportunities for gravity separation that occur in the normal course of processing, but particles which disentrain too slowly and can not be filtered remain in suspension to the possible detriment of product quality.1995, M. A. Kozlowski, S. A. Argyropoulos, R. W. McBean, Quality in Non-ferrous Pyrometallurgy
   • Nevertheless, many species of phytoplankton that are non-motile and are unencumbered by skeletal ballast (or the gas-filled spaces to offset it) survive through maintaining a state in which they do not travel far after disentrainment.2006, C. S. Reynolds, The Ecology of Phytoplankton, →ISBN, page 82
2. The disruption of patterns of brain activity.
   • We might imagine a wave of activity, or reentrainent, among the cells making up a model, an activity having a beginning, a series of transformative phases (discrete entrainments, disentrainments, and reentrainments), and an ending.2006, Charles Don Keyes, Brain Mystery Light and Dark: The Rhythm and Harmony of Consciousness, →ISBN
   • A sudden overshoot during the postictal stage followed by significant disentrainment indicates the resetting feature of the seizure (the seizure restores the pre-seizure entrainment to a more normal state).2008, Panos M. Pardalos, Vladimir L. Boginski, Alkis Vazacopoulos, Data Mining in Biomedicine, →ISBN, page 549
3. Disruption of the natural alignment of circadian rhythms with the natural environment
   • In contrast, during disentrainment mean REM period duration remained essentially constant across all REM periods recorded during nocturnal sleep episodes1987, Angelos Halaris, Chronobiology and Psychiatric Disorders, page 123
   • Throughout disentrainment, while living in temporal isolation and given limited behavioral options, subjects were encouraged not to structure their days, but to eat and sleep whenever they felt inclined to do so.1995, Sleep Research - Volume 24, page 514
