1. 1. Reality-based brain-computer interaction

   Författare :Daniel Sjölie; Lars-Erik Janlert; Johan Eriksson; John Waterworth; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; reality-based brain-computer interaction; virtual reality; reality-based interaction; brain-computer interface; activity theory; the free-energy principle; grounded cognition; Cognitive science; Kognitionsvetenskap; Computer science; Datalogi; människa-datorinteraktion; människa-datorinteraktion;

   Sammanfattning : Recent developments within human-computer interaction (HCI) and cognitive neuroscience have come together to motivate and enable a framework for HCI with a solid basis in brain function and human reality. Human cognition is increasingly considered to be critically related to the development of human capabilities in the everyday environment (reality). LÄS MER

3. 2. Temporal representation of Motor Imagery : towards improved Brain-Computer Interface-based strokerehabilitation

   Författare :Jonatan Tidare; Elaine Åstrand; Pawel Herman; Mälardalens högskola; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; brain-computer interface; eletroencephalogram; stroke rehabilitation;

   Sammanfattning : Practicing Motor Imagery (MI) with a Brain-Computer Interface (BCI) has shown promise in promoting motor recovery in stroke patients. A BCI records a person’s brain activity and provides feedback to the person in real time, which allows the person to practice his or her brain activity. LÄS MER

4. 3. 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.

5. 4. On Calibration Algorithms for Real-Time Brain-Computer Interfaces

   Författare :Frida Heskebeck; Institutionen för reglerteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : A Brain-Computer Interface (BCI) is a system that, in real-time, translates the user's brain activity into commands that can be used to control applications, such as moving a cursor on the screen. The translation is made possible by machine learning methods and other algorithms. LÄS MER

7. 5. A Helping Hand : On Innovations for Rehabilitation and Assistive Technology

   Författare :Mats Nilsson; Hans von Holst; Metin Akay; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hand function; Mechatronic system; Orthose; Neurological rehabilitation; Brain-Computer Interface; Functional Electric Stimulation;

   Sammanfattning : This thesis focuses on assistive and rehabilitation technology for restoring the function of the hand. It presents three different approaches to assistive technology: one in the form of an orthosis, one in the form of a brain-computer interface combined with functional electrical stimulation and finally one totally aiming at rehabilitating the nervous system by restoring brain function using the concept of neuroplasticity.
