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

    Författare :Gustav Lind; Neurofysiologi; []
    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

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

    Författare :Lars Wallman; Avdelningen för Biomedicinsk teknik; []
    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.

  4. 3. Nanowires and Neural interfaces. Biocompatibility in the brain

    Författare :Lina Gällentoft; NanoLund: Centre for Nanoscience; []
    Nyckelord :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

  5. 4. Intraocular and intracranial transplantation of neural tissue : Studies on hypothalamic and hippocampal neuros

    Författare :Hanna Bergman; Pertti Panula; Linköpings universitet; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : Previous studies has demonstrated the possibility to transplant monoaminergic neurons intracranially and to the anterior chamber of the eye, where these neurons continue to develop into functional, transmitter expressing cells. In the present study, investigations were undertaken to examine the development of transplanted hypothalamic and hippocampal neurons in the rat. LÄS MER

  7. 5. Cellulose-derived conductive nanofibrous materials for energy storage and tissue engineering applications

    Författare :Volodymyr Kuzmenko; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; neural cells; supercapacitors; hydrogel inks; carbonization; cellulose; carbon composites; tissue engineering; energy storage; carbon nanofibers; 3D printing; electrospinning;

    Sammanfattning : There is no doubt that nanofibrous materials are among the most opportune materials used in advanced applications nowadays. To supply anticipated high demand for these materials sustainable resources such as plant derived polymers should be explored. LÄS MER
