1. Merging electronics and the brain - towards a fully biocompatible neural interface
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. Silicon neural interfaces -Design and biomedical aspects-
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. Strategies in Cochlear Nerve Regeneration, Guidance and Protection : Prospects for Future Cochlear Implants
Sammanfattning : Today, it is possible to restore hearing in congenitally deaf children and severely hearing-impaired adults through cochlear implants (CIs). A CI consists of an external sound processor that provides acoustically induced signals to an internal receiver. LÄS MER
4. Nanoparticle-based drug delivery systems for neural interfaces - a novel approach for improved biocompatibility
Sammanfattning : The overall purpose of this thesis was to reduce brain tissue responses around implanted microelectrodes using a pharmacological strategy. One of the main aims was to develop and evaluate drug delivery systems that allow local administration of anti-inflammatory pharmaceutics. LÄS MER
5. Development of highly biocompatible neuro-electronic interfaces towards monitoring authentic neuronal signaling in the brain
Sammanfattning : Background: To understand how the neuronal circuits in the brain process information there is a need for novelneuro-electronic interfaces that can interact chronically with brain tissue with minimal disturbance of thephysiological conditions in the tissue, in awake and freely moving animals. For this, there is a need for implantableneuro-electronic interfaces that are mechanically compliant with the tissue and that can remain positionally stablewith respect to the neurons, despite the continuous micromotions in the brain.
