1. 1. Decoding Steady-State VisualEvoked Potentials(SSVEPs)- Implementation and Performance Analysis

   University essay from Uppsala universitet/Institutionen för informationsteknologi

   Author : Peipei Han; [2020]
   Keywords : ;

   Abstract : Steady-state visual evoked potential (SSVEP)-based brain-computer interfaces(BCIs) have been widely investigated. Algorithms from the canonical correlation analysis(CCA) family perform extremely well in detecting stimulus targets by analyzing the relationship of frequency features between electroencephalogram (EEG) signals and stimulus targets.

3. 2. Engaging through design : Visualizing climate impact of aviation at KTH

   University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Author : Nike Backman; Maria Jacobson; [2020]
   Keywords : ;

   Abstract : As the state of the climate becomes increasingly severe, a multitude of goals are being formed in order to tackle the problem. At KTH Royal Institute of Technology, goals to lower emissions from work related air travel have been set. READ MORE

4. 3. Attentional selection and suppression in non-clinical adults : An event-related potential study

   University essay from Högskolan i Skövde/Institutionen för biovetenskap

   Author : Oscar Magnusson; [2020]
   Keywords : Attention deficit hyperactivity disorder; everyday life attention scale; selective attention; target-evoked N2pc; distractor-evoked PD;

   Abstract : Attention deficit hyperactivity disorder (ADHD) is a neurodevelopmental disorder that manifests as a developmentally inappropriate pattern of inattention, and hyperactivity or impulsivity. ADHD is a multifactorial disorder with inter alia deficits in selective attention processing. READ MORE

5. 4. Is Visual Stimuli Neighboring Attended Stimuli Suppressedin High Perceptual Load? : A Steady State Evoked Potential Study

   University essay from Linköpings universitet/Institutionen för datavetenskap

   Author : Linn Bergström; [2016]
   Keywords : ;

   Abstract : Perceptual load theory, together with the surround-suppression model suggest that stimulus surrounding attended stimuli is suppressed, especially if perceptual load is high. This study attempts to map surround-suppression using electroencephalography to measure neural activity related to suppression at four surrounding locations (2°, 3°, 4° and 6° from fixation).

6. 5. 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
