Bianchi MT, Thomas RJ. Technical advances in the characterization of the complexity of sleep and sleep disorders. Proc Neuropsychopharmacol Biol Psychiatry. 2013; 1(45): 277-86. DOI: 10.1016/j.pnpbp.2012.09.017
A review of the spectrum of approaches that have been leveraged towards improved understanding of the complexity of sleep.
The complexity of sleep physiology has inspired alternative metrics that are providing additional insights into the rich dynamics of sleep. Electro-encephalography, magneto-encephalography, and functional magnetic resonance imaging represent advanced imaging modalities for understanding brain dynamics.
These methods are complemented by autonomic measurements that provide additional important insights.
