1. U-Sleep accepts input signals obtained with any common electrode placement (i.e., any EEG and EOG channel), hardware and software filtering, and sampling rate (internally re-sampled to 128 Hz). Up to computer memory constraints, U-Sleep processes inputs of arbitrary lengths. However, ...
No multi-channel fusion was employed in this study. Sleep-EDF database [82]. Supratak et al. [90 ], 2017 Automatic sleep staging in single channel EEG (Fpz-Cz or Pz-Oz) A convolutional RNN (CRNN) was constructed to work directly of the raw signal data. Two branches of CNN, each ...
The apnea-hypopnea index (AHI) is equal to the average number of episodes of apnea and hypopnea per hour of sleepwithout the use of a positive airway pressure device. Sleep time can only be measured in a Type I (facility-based polysomnogram) or Type II sleep study. Thus the AHI is r...
1 The EEG and Neural Synchrony The scalp recorded EEG, along with local brain field potentials, are generated by postsynaptic excitatory and inhibitory graded potentials that are synchronized across a large number of neurons in close proximity.3 While the scalp EEG and local field potentials do not...
Body functions such as EEG and muscle tone are measured in polysomnography. The period needed from wakefulness to sleep onset is measured to determine the "sleep latency." This is repeated during each of the naps, and an average time for sleep latency across all the naps is calculated. ...

When it comes to the measurement of sleep, polysomnography (PSG) is the gold standard sleep study procedure that simultaneously monitors the electroencephalogram (EEG), electro-oculogram (EOG), electromyogram (EMG), electrocardiogram (ECG), and pulse oximetry, as well as airflow and respiratory ...
The Institutional Review Board (IRB) at the University of Michigan approved this study (IRB#HUM00069035). Full polysomnography (PSG) data was collected for 96 patients at the University of Michigan Sleep Disorders Center. For each patient, polysomnography consisted of electroencephalography (EEG), ...
Our study provides compelling evidence supporting a causal relationship between the early EEG response following PTAS, resembling evoked KCs, and the consolidation of verbal declarative memory, as evidenced by a significant improvement in verbal memory performance among healthy adults. Opting for down- ov...
