Sammanfattning : Within the field of neuroprosthetics the possibility to use implanted electrodes for communication with the nervous system is explored. Much effort is put into the material aspects of the electrode implant to increase charge injection capacity, suppress foreign body response and build micro sized electrode arrays allowing close contact with neurons.

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. LÄS MER
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. 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
Sammanfattning : Implantable neural interfaces are microelectronic systems, which have the potential to enable a wide range of applications, such as diagnosis and treatment of neurological disorders. These applications depend on neural interfaces to accurately record electrical activity from the surface of the brain, referred to as electrocorticography (ECoG), and provide controlled electrical stimulation as feedback.
