1. 1. A novel implantable ultra-flexible brain machine interface. Manufacturing and initial characterisations

   Författare :Fotios Tsanakalis; Neuronano Research Center (NRC); []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Brain-Machine Interfaces; BMIs; Neural Interfaces; Electrodes;

   Sammanfattning : This thesis describes for the very first time the development of a miniaturized neural interface which is flexible in three dimensions (3D) to enable it to follow the brain movements with minimal dislocation. Both the design rationale and the material choice for the electrodes aim to develop interfaces that minimize the damage and/or the irritation of the tissue during and after the implantation. LÄS MER

3. 2. Signal Modeling and Data Reduction for Wireless Brain-Machine Interfaces

   Författare :Palmi Thor Thorbergsson; Institutionen för elektro- och informationsteknik; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Extracellular neural recordings; wireless brain-machine interfaces; signal modeling; data reduction; compression;

   Sammanfattning : Brain-machine interfaces (BMIs) provide a uni- or bidirectional communication link between the central nervous system and the outside world. This link facilitates the studying of neuronal mechanisms underlying behavior as well as the treatment of neurological disease. LÄS MER

4. 3. Stimulating the Brain : Ethical Perspectives on Deep Brain Stimulation & Nano Scaled Brain Machine Interfaces

   Författare :Veronica Johansson; Centrum för teologi och religionsvetenskap; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

   Sammanfattning : This thesis addresses some of the ethical concerns raised by connecting man and machine through so called Brain-Machine Interfaces, BMIs, elaborate brain implants that may both further our knowledge of the brain and alleviate neurological dysfunction and impairments. The primary foci have been to address urgent and prominent concerns elicited by BMIs; to critically evaluate arguments relevant to an ethical analysis of Deep Brain Stimulation, DBS; and to address and develop ignored or underrepresented perspectives of importance in an ethical analysis of DBS.

5. 4. Development of highly biocompatible neuro-electronic interfaces towards monitoring authentic neuronal signaling in the brain

   Författare :Johan Agorelius; NanoLund: Centre for Nanoscience; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; BMI; brain machine interface; Neuro-electronic interface; neurophysiology; brain computer interface; biocompatibility; biocompatible neural interface; neural interface; histology; electrophysiology;

   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.

7. 5. A tailored biocompatible neural interface for long term monitoring in neural networks

   Författare :Per Köhler; Neuronano Research Center (NRC); []
   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
