EEG Characteristics:
Physiology:
Electroencephalography (EEG) is the primary noninvasive tool for measuring brain electrical activity and is central to characterizing sleep. Sleep is an active, regulated physiological state composed of multiple stages with distinct EEG signatures that reflect underlying neural network dynamics. Understanding EEG patterns across wakefulness and sleep informs basic neuroscience, clinical sleep medicine, and cognitive research. eeg and sleep physiology ppt

Speaker Notes: "By the end of this session, you should be able to look at an EEG hypnogram and understand exactly what is happening physiologically. We will move from the cellular level of how the signal is generated to the macro level of sleep staging." EEG Characteristics:
