1. 11. Development of an fMRI-based communication protocol for unresponsive patients

   University essay from Umeå universitet/Institutionen för psykologi

   Author : Lichen Ma; [2016]
   Keywords : Unresponsive wakefulness syndrome; communication protocol; motor imagery; fMRI;

   Abstract : Recent studies using functional magnetic resonance imaging (fMRI) have reported that a subset ofpatients suffering from Unresponsive Wakefulness Syndrome (UWS, or vegetative state) were able toreliably follow instructions and perform mental imagery or attention tasks. Based on these finding,efforts were directed towards developing a communication protocol based on command-following. READ MORE

3. 12. Challenges With Session to Session Managementin Brain Computer Interfaces : A Comparison of Classification Methods for Motor Imagery Induced EEG Patterns

   University essay from KTH/Skolan för datavetenskap och kommunikation (CSC)

   Author : CHRISTOFFER PETTERSSON; ERIC SCHMIDT; [2014]
   Keywords : ;

   Abstract : Brain computer interfaces (BCIs) enable communication between a brain and a computer, without the need for any motor actions. Electroencephalography (EEG) signals can be used as input for a BCI, but they need to go through a number of steps in the BCI to create useableoutput. READ MORE

4. 13. EEG enhancement for EEG source localization in brain-machine speller

   University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

   Author : Parinaz Babaeeghazvini; [2013]
   Keywords : Brain-Computer interface BCI ; Brain-machine speller; Electroencephalogram EEG ; source localization; source reconstruction;

   Abstract : A Brain-Computer Interface (BCI) is a system to communicate with external world through the brain activity. The brain activity is measured by Electro-Encephalography (EEG) and then processed by a BCI system. EEG source reconstruction could be a way to improve the accuracy of EEG classification in EEGbased brain–computer interface (BCI). READ MORE

5. 14. A Unified Perspective of Unilateral Spatial Neglect

   University essay from Institutionen för kommunikation och information

   Author : Joel Gerafi; [2012]
   Keywords : Attention; hemispace; hemisphere; unilateral spatial neglect; stroke;

   Abstract : The aim of this review is to provide a unified perspective of unilateral spatial neglect (USN). USN is a neurological disorder frequently observed following damage or diseases to the brain. It is particularly associated with strokes to specific anatomical structures within the right hemisphere.

6. 15. Analysis of EEG Signals for EEG-based Brain-Computer Interface

   University essay from Akademin för innovation, design och teknik

   Author : PAROKARAN JESSY; [2009]
   Keywords : ;

   Abstract : Advancements in biomedical signal processing techniques have led Electroencephalography (EEG) signals to be more widely used in the diagnosis of brain diseases and in the field of Brain Computer Interface(BCI). BCI is an interfacing system that uses electrical signals from the brain (eg: EEG) as an input to control other devices such as a computer, wheel chair, robotic arm etc. READ MORE
