  1. 1. To select one hand while using both : neural mechanisms supporting flexible hand dominance in bimanual object manipulation

    Author : Anna Theorin; Roland Johansson; Fredrik Ullén; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; object manipulation; bimanual coordination; action selection; cerebral cortex; functional laterality; humans; hand; magnetic resonance imaging; transcranial magnetic stimulation; electromyography; Physiology; Fysiologi; fysiologi; Physiology;

    Abstract : In daily activities, the brain regularly assigns different roles to the hands dependingon task and context. Yet, little is known about the underlying neural processes. Thiscertainly applies to how the brain, where each hemisphere primarily controls onehand, manages the between-hand coordination required in bimanual objectmanipulation. READ MORE

  2. 2. Cerebral Perfusion and Metabolism during Experimental Extracorporeal Circulation

    Author : Ove Jonsson; Stefan Thelin; Fredrik Lennmyr; Sven-Erik Ricksten; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; cerebral perfusion; Experimental brain research; Experimentell hjärnforskning; Thoraxkirurgi; Thorax Surgery;

    Abstract : Neurologic injuries are major causes of mortality and morbidity after cardiac surgery. This thesis aimed to investigate cerebral metabolism and perfusion abnormalities in pigs during hypothermic circulatory arrest, selective antegrade cerebral perfusion (SACP) and extracorporeal circulation following progressive venous stasis.

  3. 3. Ion channels and electrical activity in vascular smooth muscle: Effects of calcium store depletion, cholesterol and cholesterol-lowering drugs

    Author : Andreas Bergdahl; Kärlfysiologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Fysiologi; Physiology; statins; endothelin; cholesterol; caveolae; smooth muscle; TRP; Ca2 channels; SOC;

    Abstract : Smooth muscle cells (SMCs) in the vessel wall contract to regulate blood flow and pressure, a function essential for normal circulation through tissues. On the other hand, migration and proliferation of SMCs are important factors in vascular disease, such as atherosclerosis and restenosis following surgical dilatation. READ MORE

  4. 4. The EEG of the Neonatal Brain – Classification of Background Activity

    Author : Johan Löfhede; Högskolan i Borås; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; hypoxia; newborn; segmentation; asphyxia; cerebral; classification; neonatal; EEG;

    Abstract : The brain requires a continuous supply of oxygen and nutrients, and even a short period of reduced oxygen supply can cause severe and lifelong consequences for the affected individual. The unborn baby is fairly robust, but there are of course limits also for these individuals. The most sensitive and most important organ is the brain. READ MORE

  5. 5. MUSCLE STRENGTH, GROSS MOTOR FUNCTION AND GAIT PATTERN IN CHILDREN WITH CEREBRAL PALSY

    Author : Meta Nyström Eek; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; child; muscle strength; reference values; cerebral palsy; motor skills; gait; resistance training;

    Abstract : Aim The main purpose was to explore the relationship between muscle strength and walking ability in children with bilateral spastic cerebral palsy (CP), and to analyse whether muscle strength training can improve walking ability. Another aim was to establish normative values for muscle strength in terms of torque in typically developing children and adolescents, and in relation to sex, age and body weight. READ MORE
