16. The Physical Axon : Modeling, Simulation and Electrode Evaluation
Sammanfattning : 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. LÄS MER
17. Computational Models in Deep Brain Stimulation : Patient‐Specific Simulations, Tractography, and Group Analysis
Sammanfattning : 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. LÄS MER
18. Optical Monitoring of Cerebral Microcirculation
Sammanfattning : 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).

19. Fluorescence Guided Resection of Brain Tumors : Evaluation of a Hand-held Spectroscopic Probe
Sammanfattning : 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. LÄS MER
20. Deep Brain Stimulation Atlases in Movement Disorders : from Patient-Specific to Group Analysis
Sammanfattning : 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. LÄS MER
