1. 6. Clinical aspects of olfaction

   Författare :Annika Brämerson; Göteborgs universitet; []
   Nyckelord :olfactory disorders; epidemiology; quality of life; diagnosis; event-related potentials; radiation therapy;

   Sammanfattning : The most important aims of this thesis were: (1) to investigate the prevalence of olfactory dysfunction in an adult Swedish population and to relate dysfunction to factors of possible impact on olfaction, (2) to present our experience with patients seeking medical attention for olfactory disorders, (3) to describe the relationship between detection and identification tests for olfactory disorders, (4) to assess olfactory event-related potentials (OERPs) in patients with olfactory impairment and in healthy controls, thereby exploring possibilities and limitations regarding to the clinical utility of the method, and (5) to evaluate the effect on the sense of smell of radiation in patients treated for head and neck cancer. Materials and methods: In the population-based study, 1900 adult subjects were drawn from the municipal register (I). LÄS MER

3. 7. How the past becomes present : neural mechanisms governing retrieval from episodic memory

   Författare :Kristiina Kompus; Lars Nyberg; Katrine Åhlström Riklund; Emrah Düzel; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; episodic retrieval; cognitive control; retrieval intention; prefrontal cortex; functional magnetic resonance imaging; event-related potentials; Neurophysiology; Neurofysiologi; diagnostisk radiologi; Diagnostic Radiology;

   Sammanfattning : Remembering previously experienced events can happen as a result of an effortful retrieval attempt. At other occasions, a memory can enter our minds without any apparent effort – or, indeed, intention - to retrieve. LÄS MER

4. 8. The neurophysiology of grammatical constraints : ERP studies on the influence of prosody and pragmatics on the processing of syntax and morphology in Swedish

   Författare :Mikael Roll; Allmän språkvetenskap; []
   Nyckelord :HUMANIORA; HUMANITIES; linguistics; event-related potentials; ERP; pragmatics; language processing; prosody; syntax;

   Sammanfattning : This dissertation investigates the interaction of information from word order, morphology, lexical semantics, and prosody in the on-line processing of Swedish sentences using Event-Related Potentials. Study I examines how the form, meaning, and syntactic position of objects influence their interpretation in ‘Object Shift’ contexts. LÄS MER

5. 9. Executive functions and ERP Biomarkers in children and adolescents with ADHD and Autism

   Författare :Linda Angelica Häger; Göteborgs universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Supplementary biomarkers; Child psychiatry; ADHD; Autism; Executive function; Neuropsychological tests; Event related potentials; EEG;

   Sammanfattning : Executive Functions (EF) refers to skills that help us initiate, organize and evaluate activities. Problems with EF are associated with neurodevelopmental disorders such as Attention Deficit Hyperactivity Disorder (ADHD) and autism spectrum disorder (ASD). LÄS MER

7. 10. Prior Knowledge and Recognition Memory : a Computational Modeling Approach

   Författare :Johan Hellman; Institutionen för psykologi; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Recognition memory; Episodic memory; Pre-experimental familiarity; Event-Related Potentials; Item variability; Receiver-Operating Characteristics; Computational Models;

   Sammanfattning : For more than a century, an immense interest has been devoted to the study of recognition memory, where a multitude of memory phenomena has been explained. Recognition memory is usually described with parsimonious measurement and statistical models, stemming from dual process theory and signal detection theory. LÄS MER
