   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Earthquake location; Earthquake relocation; Tremor location; Bayesian inversion; Correlation; Earthquake catalog; Iceland; Seismicity; Interferometry; Inverse theory; Volcanic tremor; Geofysik med inriktning mot seismologi; Geophysics with specialization in Seismology;

   Abstract : This dissertation is a comprehensive summary of four papers on the development and application of new strategies for locating tremor and relocating events in earthquake catalogs.In the first paper, two new strategies for relocating events in a catalog are introduced. READ MORE

4. 2. Deep brain stimulation targeting the caudal zona incerta as a treatment for parkinsonian and essential tremor

   Author : Rasmus Stenmark Persson; Patric Blomstedt; Sara af Bjerkén; Marwan Hariz; Anders Fytagoridis; Alfonso Fasano; Umeå universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; movement disorders; parkinson s disease; tremor; essential tremor; deep brain stimulation; zona incerta; posterior subthalamic area; Neurology; neurologi; neurokirurgi; Neurosurgery;

   Abstract : Background: Deep brain stimulation (DBS) is used as a treatment for Parkinson’s disease (PD) and Essential tremor (ET) when medications are insufficient. The most common DBS-targets for PD and ET, the subthalamic nucleus (STN) and the ventral intermediate nucleus of the thalamus (Vim) respectively, have certain side effects and limitations. READ MORE

5. 3. Impact of deep brain stimulation in the caudal zona incerta on voice tremor and speech in persons with essential tremor

   Author : Linda Sandström; Fredrik Karlsson; Patric Blomstedt; Lena Hartelius; Adam Vogel; Umeå universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; caudal zona incerta; deep brain stimulation; essential tremor; speech function; speech intelligibility; speech production; voice tremor;

   Abstract : Objectives: Deep brain stimulation (DBS) is a symptomatic treatment for people with essential tremor (ET) who have unsatisfactory tremor relief with pharmacological treatment alone. A common symptom of ET is voice tremor, but only about 50% of patients with voice tremor get a satisfactory result with DBS. READ MORE

6. 4. Stereotactic functional procedures in the treatment of essential tremor

   Author : Ulrika Sandvik; Patric Blomstedt; Lars-Owe Koskinen; Stig Rehncrona; Umeå universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Essential Tremor; Stereotactic Functional Neurosurgery; Deep Brain Stimulation; Posterior Subthalamic Area; Thalamotomy; Zona incerta; caudal Zona incerta; Quality of Life; Vim; neurokirurgi; Neurosurgery;

   Abstract : Background: Essential tremor (ET) is the most common movement disorder. In cases resistant to pharmacological treatment, functional stereotactic neurosurgery can be an alternative. Lesional surgery has largely been replaced by deep brain stimulation (DBS). The current target of choice is the ventrolateral thalamus (Vim). READ MORE

7. 5. Stereotactic imaging in functional neurosurgery

   Author : Hidehiro Hirabayashi; Patric Blomstedt; Takaomi Taira; Umeå universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Deep brain stimulation; pallidotomy; thalamotomy; Parkinson s disease; essential tremor; CT; MRI; neurokirurgi; Neurosurgery;

   Abstract : Background: The birth of stereotactic functional neurosurgery in 1947 was to a great extent dependent on the development of ventriculography. The last decades have witnessed a renaissance of functional stereotactic neurosurgery in the treatment of patients with movement disorders. READ MORE
