    Abstract : Anxiety disorders are very common and the primary feature is abnormal or inappropriate anxiety. Fear and anxiety is often mediated by the amygdala, a brain structure rich in substance P (SP) and neurokinin 1 (NK1) receptors. READ MORE

  2. 2. Train your brain updating, transfer, and neural changes

    University dissertation from Umeå : Department of Integrative Medical Biology, Section for Physiology, Umeå university

    Author : Erika Dahlin; Umeå universitet.; Umeå universitet.; Umeå universitet.; [2009]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; cognitive training; executive functioning; transfer; fMRI; brain system; young adults; elderly; practice; neural correlates; individual differences; MEDICINE Physiology and pharmacology Physiology Experimental brain research; MEDICIN Fysiologi och farmakologi Fysiologi Experimentell hjärnforskning; SOCIAL SCIENCES Social sciences Psychology Cognitive science; SAMHÄLLSVETENSKAP Socialvetenskap Psykologi Kognitionsforskning; fysiologi; Physiology;

    Abstract : An initial aim of this thesis was to determine whether training of a specific executive function (updating) produces improvements in performance on trained and transfer tasks, and whether the effects are maintained over time. Neural systems underlying training and transfer effects were also investigated and one question considered is whether transfer depends on general or specific neural overlap between training and transfer tasks.

  3. 3. Impact of Tissue Characteristics on Radio-Frequency Lesioning and Navigation in the Brain Simulation, experimental and clinical studies

    University dissertation from Linköping : Linköping University Electronic Press

    Author : Johannes Johansson; Linköpings universitet.; Linköpings universitet.; [2009]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Brain; Radio frequency ablation; Finite element method; Monte Carlo simulation; light reflectance; MEDICINE Physiology and pharmacology Radiological research; MEDICIN Fysiologi och farmakologi Radiologisk forskning;

    Abstract : Radio-Frequency (RF) lesioning, or RF ablation, is a method that uses high frequency currents for thermal coagulation of pathological tissue or signal pathways. The current is delivered from an electrode, which also contains a temperature sensor permitting control of the current at a desired target temperature. In the brain, RF lesioning can e.g. READ MORE

  4. 4. MRI Diagnosis of Intracranial Hemorrhage Experimental and Clinical Studies

    University dissertation from Uppsala : Institutionen för onkologi, radiologi och klinisk immunologi

    Author : Montserrat Alemany Ripoll; Uppsala universitet.; [2003]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Radiology; hemorrhage; experimental; MRI; T2*-w GE sequence; old microhemorrhages; stroke; Radiologisk forskning; MEDICINE Physiology and pharmacology Radiological research; MEDICIN Fysiologi och farmakologi Radiologisk forskning; radiologi; Radiology;

    Abstract : The purpose of this work was to improve the diagnosis of intracranial hemorrhage with MRI, using, among others, T2*-w GE sequences. Various sequences were tested in rabbits at two magnetic field strengths. Then, the most effective technique was applied to stroke patients. READ MORE

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

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Ove Jonsson; Uppsala universitet.; [2011]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; cerebral perfusion; MEDICINE Physiology and pharmacology Physiology Experimental brain research; MEDICIN Fysiologi och farmakologi Fysiologi 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.
