Methods for Generalized Low-Dimensional EEG Analysis Using Transfer Learning
… (PSG) is a widely used procedure for diagnosing sleep disorders such as narcolepsy and sleep apnea, however its invasive and time-consuming nature make it infeasible for any form of long-term monitoring. It requires patients to sleep in a hospital setting for several nights while their EEG and …

Quality of heart rate variability features obtained from ballistocardiograms
… including long-term health monitoring and sleep quality assessment. The focus of this research is obtaining HRV from ballistocardiograms (BCGs), force signals caused by micro-movements of the human body in response to blood ejections. This method of HRV estimation is attractive because it …

Evaluation of an accessible automatic sleep spindle detector
An important component of sleep medicine is assessing a patient’s polysomnogram, which includes sleep staging. The American Academy of Sleep Medicine (AASM) requires that sleep staging must take into account the number of sleep spindles, a short burst of neural oscillatory activity, demonstrating …

Towards Perceptual Augmentation
… perception, pilot situation awareness, and sleep staging. The research does not yet demonstrate a generalized, "all-purpose" augmented sense, but lays groundwork for future investigations, including a proposed experiment to mitigate age-related hearing loss using the developed principles.

Into the Wild: Deploying Brain and Physiological Sensing in Natural Environments to Enhance Wake and Sleep Cognitive Behavioral Studies
… natural settings: one for wake time and one for sleep. The equipment utilized today in behavioral and sleep labs is not very accessible, comfortable, portable, or simple to operate. The systems documented in this dissertation demanded the creation of novel wearables, sensors, signal processing, …

Interfacing with Dreams : Novel Technologies and Protocols for Targeted Dream Incubation
Scientific research into relationships between sleep physiology and waking cognition has progressed dramatically in the past few decades, but research on the basic science, function, and health consequences of dream phenomenology has not. This dissertation describes research into novel devices and …

Investigation of Sleep Neural Dynamics in Intracranial EEG Patients
… purposes; however, to use this data for basic sleep research the challenge lies in identifying the precise locations of the implanted electrodes’ recording sites in terms of neuroanatomical regions as well as reliable scoring of their sleep data without the aid of facial electrodes. While …

Electroencephalographic effects of general anaesthetics : a suite of clinical studies and theoretical models
… clinical and EEG studies of anaesthesia and sleep. These were done to confirm and clarify some of the theoretical results from the models. However there are many different ways of numerically capturing the information contained within the EEG. Because this problem needed to be overcome before …

Μελέτη εγκεφαλογραφικών ρυθμών ως συμβολή στη φυσιολογία του ύπνου και την παθοφυσιολογία επιληπτικών συνδρόμων
Η μελέτη των εγκεφαλογραφικών ρυθμών του ύπνου μπορεί να δώσει πληροφορίες για τους υποκείμενους νευροφυσιολογικούς μηχανισμούς που ελέγχουν και οργανώνουν τον φυσιολογικό ύπνο. Το θαλαμοφλοιικό κύκλωμα και τα συστήματα εγρήγορσης του δικτυωτού σχηματισμού είναι δυο νευρικά κυκλώματα με κεντρικό …
