Objectives:
A review of the spectrum of approaches that have been leveraged towards improved understanding of the complexity of sleep.
Conclusions:
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.
Practical Significance:
These methods are complemented by autonomic measurements that provide additional important insights.
