  1. 1. Brain processing of experimental muscle pain and its interrelation with proprioception and muscle fatigue : positron emission tomography study

    Författare :Alexander Korotkov; Docent Tomas Graven-Nielsen; Umeå universitet; []
    Nyckelord :Experimental muscle pain; Hypertonic saline; Kinesthesia; Proprioception; Movement; Vibration; Muscle fatigue; Brain; Imaging; Positron emission tomography; Regional cerebral blood flow; Movernent; Positron emission tornography; Regional cerebral blood - flow;

    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

  3. 2. Imaging fear and anxiety in the human brain : Positron emission tomographic studies

    Sammanfattning : Positron emission tomography (PET) is a tracer technique used for quantitative in vivo studies of physiological and biochemical processes. Because of the use of positron-emitting radionuclides such as 11-C, 13-N, 15-O and 18-F, which are isotopes of the biologically ubiquitous elements, it is possible to label radiopharmaceuticals which trace biochemical processes precisely.

    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
