  1. 1. Cerebral Injury in Perinatal Asphyxia, epidemiological, clinical, neurophysiological and neuromatabolic investigations

    Författare :Kristina Thorngren-Jerneck; Lund Pediatrik; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; neuropsychology; neurophysiology; Neurologi; neuropsykologi; neurofysiologi; Neurology; Pediatri; Pediatrics; S100; EEG; CMRgl; cerebral glucose metabolism; FDG-PET; CP; infant; perinatal asphyxia; hypoxia-ischemia;

    Sammanfattning : Perinatal asphyxia with hypoxic ischemic encephalopathy (HIE) is the most important cause of perinatal mortality and cerebral palsy (CP) in infants born at term. The aim of the thesis was to investigate epidemiology of perinatal asphyxia, and to investigate early clinical neurological symptoms after perinatal asphyxia in relation to cerebral glucose metabolism (CMRgl) measured by 18-FDG-PET, neurophysiological function, some biochemical markers, also in relation to long-term outcome.

  2. 2. Development of highly biocompatible neuro-electronic interfaces towards monitoring authentic neuronal signaling in the brain

    Sammanfattning : Background: To understand how the neuronal circuits in the brain process information there is a need for novelneuro-electronic interfaces that can interact chronically with brain tissue with minimal disturbance of thephysiological conditions in the tissue, in awake and freely moving animals. For this, there is a need for implantableneuro-electronic interfaces that are mechanically compliant with the tissue and that can remain positionally stablewith respect to the neurons, despite the continuous micromotions in the brain.

  3. 3. Stroke in geriatric patients - Aspects of depression, cognition and motor activity

    Författare :Berit Agrell; Geriatrik; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; stroke; laterality; rating scales; motoractivity; aphasia; neglect; disability; depression; cognition; Neurology; neuropsychology; neurophysiology; Neurologi; neuropsykologi; neurofysiologi;

    Sammanfattning : Six depression rating scales, GDS, Zung, CES-D, CPRS-D and Cornell, were compared in 40 patients. The validity was good for all scales except for the Cornell scale. A comprehensive investigation was done in 116 elderly stroke patients. There was no difference in prevalence and severity of post-stroke depression in relation to side of lesion. LÄS MER

  4. 4. Aspects of proteinase-activated receptor-2: A sensor of enzymatic activity at the cell surface

    Författare :Anna-Karin Alm; Institutionen för experimentell medicinsk vetenskap; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; neuropsychology; Neurology; endometrium.; coagulation; signalling; proteinase; G-protein; cell; receptor; neurophysiology; Neurologi; neuropsykologi; neurofysiologi;

    Sammanfattning : Information about extracellular proteolytic activity is transduced to the cell by a transmembrane G-protein coupled receptor subfamily. These receptors are activated by proteolytic cleavage in the extracellular amino-terminal domain and are thus termed proteinase-activated receptors (PARs). LÄS MER

  5. 5. On the Causal Mechanisms of Stuttering

    Författare :Per A Alm; Lund Neurologi; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; stuttering; neurofysiologi; neuropsykologi; neurophysiology; Neurologi; dystonia; neuropsychology; Neurology; basal ganglia;

    Sammanfattning : Stuttering is one of the most common speech disorders. However, the etiology is poorly understood, and is likely to be heterogeneous. The aim of this thesis was to clarify causal mechanisms, focusing the brain. LÄS MER
