1. Brain processing of experimental muscle pain and its interrelation with proprioception and muscle fatigue : positron emission tomography study
Sammanfattning : Chronic muscle pain is a significant medical and social problem and better understanding of the pathophysiological mechanisms involved is an important requirement for further development of diagnostics, treatment and rehabilitation methods. Experimental imaging studies have investigated functional neuroanatomy of different pain components. LÄS MER
Sammanfattning : In this thesis, the developments of two different low-cost scanners for positron emission tomography (PET) based on 3D acquisition, are presented. 3D reconstruction methods for these systems are also presented. LÄS MER
Sammanfattning : Fear and anxiety are central human experiences. However, the relation between aspects of these aversive emotional states and brain function have previously been studied mostly in animals. LÄS MER
4. Search for Biomarkers in ALS and Parkinson's Disease : Positron Emission Tomography and Cerebrospinal Fluid Studies
Sammanfattning : New biomarkers are needed to improve knowledge about pathophysiology, in order to provide earlier correct diagnosis and to follow disease progression of the neurodegenerative diseases amyotrophic lateral sclerosis (ALS) and Parkinson's disease (PD). The aim of this thesis was to find new biomarkers for these diseases. LÄS MER
