Beyond the Hypnogram: Multitaper Spectrogram Analysis of Sleep EEG

In this set of tutorials, we will explain the theory of spectral estimation and demonstrate how a technique called multitaper spectral analysis can create clear, vibrant pictures of brain dynamics during sleep — rich with information beyond what can be seen in traditional clinical hypnogram analyses.


Tracking the Sleep Onset Process

In this video tutorial, we describe a new way of tracking the continuum of sleep onset, which incorporates EEG, physiological, and behavioral information to estimate the instantaneous probability that a subject is awake at each point in time.
