  1. 16. The Physical Axon : Modeling, Simulation and Electrode Evaluation

    Author : Malcolm Latorre; Karin Wårdell; Göran Salerud; Ulrich Hofmann; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Electrodes are used in medicine for detection of biological signals and for stimulating tissue, e.g. in deep brain stimulation (DBS). For both applications, an understanding of the functioning of the electrode, and its interface and interaction with the target tissue involved is necessary. READ MORE

  2. 17. Computational Models in Deep Brain Stimulation : Patient‐Specific Simulations, Tractography, and Group Analysis

    Author : Teresa Nordin; Karin Wårdell; Simone Hemm-Ode; Johannes D. Johansson; Harith Akram; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Anisotropy; Deep brain stimulation DBS ; Finite element method FEM ; Patient‐specific simulation; Probabilistic stimulation maps PSM ; Tractography;

    Abstract : Deep brain stimulation (DBS) is an established method for symptom relief in movement disorders like Parkinson’s disease, essential tremor (ET), and dystonia. The therapy is based on implanting an electrode with four contacts in the deep brain structures where it provides electrical stimulation, mainly impacting the nerve tracts. READ MORE

  3. 18. Optical Monitoring of Cerebral Microcirculation

    Author : Peter Rejmstad; Karin Wårdell; Göran Salerud; Neda Haj-Hosseini; Kerstin Ramser; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; optical monitoring; cerebral microcirculation; diffuse reflectance spectroswcopy DRS ; laser Doppler flowmetry LDF ;

    Abstract : The cerebral microcirculation consists of a complex network of small blood vessels that support nerve cells with oxygen and nutrition. The blood flow and oxygen delivery in the microcirculatory blood vessels are regulated through mechanisms which may be influenced or impaired by disease or brain damage resulting from conditions such as brain tumors, traumatic brain injury or subarachnoid hemorrhage (SAH).

  4. 19. Fluorescence Guided Resection of Brain Tumors : Evaluation of a Hand-held Spectroscopic Probe

    Author : Johan Richter; Karin Wårdell; Jan Hillman; Peter Siesjö; Linköpings universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Malignant gliomas grow infiltrative in the brain and can therefore not be completely removed by neurosurgical means. However, for an optimized oncological treatment it has proven useful to resect as much as possible of tumor. The identification of the tumor in the marginal zone is difficult but crucial. READ MORE

  5. 20. Deep Brain Stimulation Atlases in Movement Disorders : from Patient-Specific to Group Analysis

    Author : Dorian Vogel; Karin Wårdell; Simone Hemm; Anders Eklund; Linköpings universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Abstract : deep brain stimulation (DBS) is an established method for symptom control in movement disorders such as Parkinson’s disease (PD) and essential tremor (ET). The treatment consists in delivering electrical stimulation in the deep brain via multi-contact electrodes. READ MORE
