  1. 1. Merging electronics and the brain - towards a fully biocompatible neural interface

    Detta är en avhandling från Neurophysiology

    Författare :Gustav Lind; Lunds universitet.; Lund University.; [2013]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; neural interface; neural implants; 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; Elektronik och elektroteknik; Electronics and Electrical technology; 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. Nanowires and Neural interfaces. Biocompatibility in the brain

    Detta är en avhandling från Lund University, Faculty of Medicine

    Författare :Lina Gällentoft; Lunds universitet.; Lund University.; [2016]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; neural interface; neurons; BMI; nanowires; tissue responses; rat; biocompatibility; astrocytes; microglia;

    Sammanfattning : Chronic neural interfaces that are able to record or stimulate neurons in the CNS are valuable instruments in use today and they hold great promise for the future both within neuroscience research and in the clinic. However, a major obstacle is that they show a decline in performance over time. LÄS MER

  4. 4. 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.; [2016]
    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

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

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

    Författare :Suleyman Malki; Lunds universitet.; Lund University.; [2008]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Circuit switching; Network on Chip; Vein feature extraction; Velocity measurement; Discrete-Time Cellular Neural Network; Switched broadcast; Serialized broadcast; Cellular Neural Network; Field- Programmable Gate-Array; Image processing.;

    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
