disentrainment

From disentrain +‎ -ment.

disentrainment (plural disentrainments)

1. The act or process of falling out of entrainment; precipitation form a flow or current.
   • 1995, M. A. Kozlowski, S. A. Argyropoulos, R. W. McBean, Quality in Non-ferrous Pyrometallurgy:

     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.

   • 2006, C. S. Reynolds, The Ecology of Phytoplankton, →ISBN, page 82:

     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.

   • 2012, Paul Stevenson, Foam Engineering: Fundamentals and Applications, →ISBN:

     The challenge here is to find methods of separating entrainment from the simultaneous disentrainment or collapse processes that normally also occur and may themselves be linked to any bubble break-up that has occurred.

2. The disruption of patterns of brain activity.
   • 2006, Charles Don Keyes, Brain Mystery Light and Dark: The Rhythm and Harmony of Consciousness, →ISBN:

     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.

   • 2008, Panos M. Pardalos, Vladimir L. Boginski, Alkis Vazacopoulos, Data Mining in Biomedicine, →ISBN, page 549:

     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).

   • 2009, Thomas H. Budzynski, Helen Kogan Budzynski, James R. Evans, Introduction to Quantitative EEG and Neurofeedback, →ISBN:

     A finite probability exists that the stimulus at any given time would have the right frequency and phase properties to effect the desired disentrainment that in the original ROSHI had been so carefully engineered.

   • 2010, Wanpracha Chaovalitwongse, Panos M. Pardalos, Petros Xanthopoulos, Computational Neuroscience, →ISBN:

     Within minutes of the first AED treatment (diazepam in the first patient and fospheytoin in the second patient), signs of disentrainment of the brain dynamics were observed in both patients.

3. Disruption of the natural alignment of circadian rhythms with the natural environment
   • 1987, Angelos Halaris, Chronobiology and Psychiatric Disorders, page 123:

     In contrast, during disentrainment mean REM period duration remained essentially constant across all REM periods recorded during nocturnal sleep episodes

   • 1995, Sleep Research - Volume 24, page 514:

     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.
