1. 6. A tailored biocompatible neural interface for long term monitoring in neural networks

   Författare :Per Köhler; Neuronano Research Center (NRC); []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Brain-machine interfaces; neuroinflammation; somatosensory cortex; hyperalgesia; allodynia;

   Sammanfattning : Neural interface electrodes that can record from neurons in the brain for long periods of time will be of great importance to unravel how the brain accomplishes its functions. However, current electrodes usually cause significant glia reactions and loss of neurons within the adjacent brain parenchyma. LÄS MER

3. 7. Microelectrode cluster technology for precise interactions with neuronal circuits. Towards highly specific adaptive deep brain stimulation

   Författare :Mohsin Mohammed; Neuronano Research Center (NRC); []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Neuro-electronic interfaceneural interface; neural interface; tissue reactions; deep brain stimulation; Adaptive DBS; biocompatibility; implantation method; neurosurgical tool;

   Sammanfattning : Neuro-electronic interfaces, which can be used for stable communication between neurons-computers over long periods of time, would be valuable for understanding and interacting with the nervous system. A major challenge has been to overcome the tissue reactions towards implanted electrodes. LÄS MER

4. 8. On Hardware Implementation of Discrete-Time Cellular Neural Networks

   Sammanfattning : Cellular Neural Networks are characterized by simplicity of operation. The network consists of a large number of nonlinear processing units; called cells; that are equally spread in the space. LÄS MER

5. 9. Development of a polymer based neural probe - How to record intracortical neural activity while minimizing the tissue response

   Författare :Fredrik Ejserholm; Avdelningen för Biomedicinsk teknik; []
   Nyckelord :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; Neural Probes; Electrode Modification; Polymer; Neurophysiology; OSTE ;

   Sammanfattning : Intracortical neural probes have in the last couple of years been developed from stiff single probes to stiff multi-electrode neural probes to flexible multi-electrode neural probes. One reason for the change in design is that more than one recording/stimulation electrode, as in the case with a single wire, is needed for more advanced studies. LÄS MER

7. 10. A novel implantable ultra-flexible brain machine interface. Manufacturing and initial characterisations

   Författare :Fotios Tsanakalis; Neuronano Research Center (NRC); []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Brain-Machine Interfaces; BMIs; Neural Interfaces; Electrodes;

   Sammanfattning : This thesis describes for the very first time the development of a miniaturized neural interface which is flexible in three dimensions (3D) to enable it to follow the brain movements with minimal dislocation. Both the design rationale and the material choice for the electrodes aim to develop interfaces that minimize the damage and/or the irritation of the tissue during and after the implantation. LÄS MER
