2. 1. fMRI for mapping the plastic somatotopy of primary somatosensory cortex - Development and clinical applications

   Author : Andreas Weibull; Malmö Medicinsk strålningsfysik; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; smoothing; physiological noise; spatial resolution; primary somatosensory cortex; cortical reorganisation; brain plasticity; fMRI; partial volume effects;

   Abstract : Functional magnetic resonance imaging (fMRI) is a widely used tool for studying brain function in vivo. The technique is based on acquiring brain images sensitive to the physiological response following neural activation, and hence, allows brain activity to be examined and documented. READ MORE

4. 2. Propofol changes the cytoskeletal function in neurons : An experimental study in cortical cultures

   Author : Dean Turina; Christina Eintrei; Karin Björnström Karlsson; Lindahl Sten; Linköpings universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Propofol; cytoskeleton;

   Abstract : Every day, general anaesthetics are given to a large number of patients around the world but the cellular mechanisms of how anaesthetics act are still not clear. General anaesthetics cause the intended unconsciousness, amnesia and immobility in patients, but also side effects such as a decrease in mean arterial pressure and arrhythmia, both of which contribute to complications such as heart damage and stroke.

5. 3. Cortical plasticity in response to median nerve trauma

   Author : Lotta Fornander; Karolinska Institutet; Karolinska Institutet; []
   Keywords : ;

   Abstract : Median nerve injuries in adults, repaired with nerve suture, lead to incomplete functional recovery despite improved surgical technique. This results in a reduction in quality of life, poorer working ability and a considerable expense for society. Misrouting of axons at the suture site connects regenerating axons to the wrong distal end organs. READ MORE

6. 4. Median and Ulnar Nerve Injuries in Children and Adolescents- Long-term outcome and Cerebral reorganisation

   Author : Anette Chemnitz; Malmö Handkirurgi; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

   Abstract : A peripheral nerve injury may lead to serious disability and influence the individual´s quality of life. It is considered that children can regain better sensory and motor function after a peripheral nerve injury, but the exact mechanism behind such superior recovery is not known. READ MORE

7. 5. Genomic clues to secondary injury mechanisms in brain trauma

   Author : Christina von Gertten; Karolinska Institutet; Karolinska Institutet; []
   Keywords : traumatic brain injury; cerebral cortical contusion; weight-drop model; depolarisation; gene expression; nestin; MMP-9; TIMP-1; osteopontin; CD44; hippocalcin; NMDA receptor; microarray; rat;

   Abstract : Traumatic brain injury (TBI) is a heterogenous disease that can lead to persistent disability or death. The immediate mechanical disruption of brain tissue is followed by a phase of secondary brain injury. During this phase TBI challenges clinical interventions due to its complexity. READ MORE
