1. 1. The EEG of the Newborn Brain - Detection of Hypoxia and Prediction of Outcome

   Författare :Nils Löfgren; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; telemedicine; neonatal; prediction; infraslow EEG; cerebral; entropy; asphyxia; EEG; VLFA; hypoxia; Kolmogorov complexity; qEEG; detection; spectral estimation; newborn;

   Sammanfattning : Brain function requires a continuous flow of oxygen and an insufficient supply (hypoxia) for a few minutes during the first period of life may have severe consequences; consequences which might impact both the life of the individual who has been struck and his or her family. Therefore, there is a need to find a method which can enable the detection of an insufficient oxygen supply at an early stage, before brain damage becomes permanent. LÄS MER

3. 2. Classification of Burst and Suppression in the Neonatal EEG

   Författare :Johan Löfhede; Högskolan i Borås; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; EEG; Suppression; classification; Burst; Neonate;

   Sammanfattning : The brain requires a continuous supply of oxygen and even a short period of reduced oxygen supply risks severe and lifelong consequences for the affected individual. The delivery is a vulnerable period for a baby who may experience for example hypoxia (lack of oxygen) that can damage the brain. LÄS MER

4. 3. The EEG of the Neonatal Brain – Classification of Background Activity

   Författare :Johan Löfhede; Högskolan i Borås; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; hypoxia; newborn; segmentation; asphyxia; cerebral; classification; neonatal; EEG;

   Sammanfattning : The brain requires a continuous supply of oxygen and nutrients, and even a short period of reduced oxygen supply can cause severe and lifelong consequences for the affected individual. The unborn baby is fairly robust, but there are of course limits also for these individuals. The most sensitive and most important organ is the brain. LÄS MER

5. 4. Neural and Cognitive Effects of Hearing Loss on Speech Processing

   Författare :Eline Borch Petersen; Thomas Lunner; Stefan Stenfelt; Jonas Obleser; Edmund Lalor; Linköpings universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Hearing loss; speech processing; electroencephalogram EEG; working memory; cognitive load; hearing aid; Hörselnedsättning; bearbetning av tal; elektroencefalogram EEG; arbetsminne; kognitiv belastning; hörapparat;

   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).

7. 5. Behavioral and Electrophysiological Correlates of Inhibition in Episodic Memory

   Författare :Gerd Waldhauser; Institutionen för psykologi; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; memory control; inhibition; EEG; ERP; forgetting;

   Sammanfattning : Forgetting can be highly functional when unwanted or irrelevant memory representations interfere with cognitive or motivational goals. Current theory assumes that forgetting can be brought about by the intentional or unintentional inhibition of interfering memory representations. LÄS MER
