    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; neural implants; neural interface; BMI; tissue reactions; biocompatibility; rat; astrocytes; microglia;

    Sammanfattning : Techniques for interfacing the nervous system using chronically implanted electrodes are turning into invaluable tools for neurophysiological research and treatment of neurological disorders. These methods have been developed and refined over the last decades. LÄS MER

  2. 2. Silicon neural interfaces -Design and biomedical aspects-

    Detta är en avhandling från Lars Wallman, Dept. of electrical measurements, box 118, 221 00 LUND

    Författare :Lars Wallman; Lunds universitet.; Lund University.; [2001]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electronics and Electrical technology; Elektronik och elektroteknik; pn-etch stop; biocompatibility; neural recordings; porous silicon; silicon; neural interface; sieve electrode; General biomedical sciences; Biomedicinska vetenskaper allmänt ;

    Sammanfattning : This thesis covers the development of a silicon neural interface, with focus on silicon sieve electrode fabrication, design, nerve regeneration, signal recording and biocompatibility. A study of how the via hole size and transparency of the perforated sieve membrane influences the nerve regeneration is presented together with a study on soft tissue responses to planar and porous silicon.

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

    Detta är en avhandling från Neuronano Research Center (NRC)

    Författare :Per Köhler; Lunds universitet.; Lund University.; Lunds universitet.; Lund University.; Lunds universitet.; Lund University.; [2016]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; neuroinflammation; Brain-machine interfaces; 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

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

    Detta är en avhandling från Department of Electrical and Information Technology, Lund University

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

    Detta är en avhandling från Department of Electrical and Information Technology, Lund University

    Författare :Fredrik Ejserholm; Lunds universitet.; Lund University.; Lunds universitet.; Lund University.; [2016]
    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; Electrode Modification; Neural Probes; 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
