1. Neural and Cognitive Effects of Hearing Loss on Speech Processing
Sammanfattning : Understanding speech in the presence of noise can be difficult, especially when suffering from a hearing loss. This thesis examined behavioural and electrophysiological measures of speech processing with the aim of establishing how they were influenced by hearing loss (internal degradation) and listening condition (external degradation).

2. Hypnosis monitoring during general anaesthesia : with focus on awareness
Sammanfattning : An objective measure of the hypnotic component of general anaesthesia has been sought for decades. The electroencephalogram (EEG) was early recognized as a possible useful intraoperative monitor when the effects of anaesthetic drugs on human EEG recordings were noted. LÄS MER
3. On methods for pattern recognition with application to epileptic electroencephalograms
Sammanfattning : The thesis treats methods for pattern recognition in multichannel electroencephalogram (EEG) signals, for application to diagnostics of epilepsy. Parts I-IV treat methods for feature extraction and clustering of EEG spikes, occurring between epileptic seizures, and part V presents a method for filtering seizure onset EEG signals. LÄS MER
4. Spectral Analysis for Signal Detection and Classification : Reducing Variance and Extracting Features
Sammanfattning : Spectral analysis encompasses several powerful signal processing methods. The papers in this thesis present methods for finding good spectral representations, and methods both for stationary and non-stationary signals are considered. LÄS MER
5. The bladder and the brain : Studies on the pathogenesis and the treatment of nocturnal enuresis
Sammanfattning : Opinions differ as to whether nocturnal enuresis is caused by high arousal thresholds, nocturnal polyuria or nocturnal bladder instability. In spite of the currently available therapeutic options - the antidiuretic drug desmopressin and alarm treatment - approximately 25% of children suffering from enuresis cannot be successfully treated.
