2. 1. Circuit Design Techniques for Implantable Closed-Loop Neural Interfaces

   Author : Nikola Ivanisevic; Ana Rusu; Saul Rodriguez; Angel Rodriguez Vazquez; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Neural interface; ECoG; high-resolution; ADC; recording; delta-sigma modulator; system identification; impedance measurements; Informations- och kommunikationsteknik; Information and Communication Technology;

   Abstract : 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.

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

   Author : Lars Wallman; Avdelningen för Biomedicinsk teknik; []
   Keywords : 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 ;

   Abstract : 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.

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

   Author : Gustav Lind; Neurofysiologi; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; neural interface; neural implants; BMI; tissue reactions; biocompatibility; rat; astrocytes; microglia;

   Abstract : 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. READ MORE

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

   Author : Fredrik Ejserholm; Avdelningen för Biomedicinsk teknik; []
   Keywords : 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; Neural Probes; Electrode Modification; Polymer; Neurophysiology; OSTE ;

   Abstract : 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. READ MORE

7. 5. Sympathetic neural blockade during regional analgesia : Clinical investigations in man

   Author : Lars-Åke Malmqvist; Linköpings universitet; []
   Keywords : MEDICINE; MEDICIN;

   Abstract : Different opinions exist concerning the extent and intensi-ty of the concomitant sympathetic block during regional blockade, and how to test the completeness of the sympathetic blockade. Studies were performed on 21 volunteers and 162 patients scheduled for surgery of the urogenital area or surgery for varicose v-eins, and chronic pain patients. READ MORE
