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. Relation between retinal morphology, visual pathway integrity and plasmatic amyloid beta 42 peptide in old and young beagles

   University essay from SLU/Dept. of Clinical Sciences

   Author : Emilia Miranda Peluso; [2020]
   Keywords : cognitive dysfunction syndrome; dog; optical coherence tomography; OCT; visual evoked potentials; VEP;

   Abstract : The spontaneously occurring behavioural syndrome referred to as canine cognitive dysfunction (CCD) is considered the canine counterpart of Alzheimer’s disease (AD). Changes in the retina such as nerve fibre layer (NFL) and ganglion cell complex (GCC) thinning have been observed in Alzheimer’s patients. READ MORE

4. 3. Processing of task-irrelevant sounds while performing a visual task : A study of auditory steady-state evoked potentials

   University essay from Stockholms universitet/Psykologiska institutionen

   Author : Jenny Arctaedius; [2020]
   Keywords : Attention; Auditory Processing; Perceptual load; ASSRs; Filtering; EEG;

   Abstract : Perceptual capacity and selection in attention have for long been an interest in cognitive science, with early theories of early selection to late selection. Hearing is an important subject to investigate when it comes to attention and early auditory processing can be investigated by using auditory steady state responses (ASSRs). READ MORE

5. 4. Merging brain-computer interfaces and virtual reality : A neuroscientific exploration

   University essay from Högskolan i Skövde/Institutionen för biovetenskap

   Author : Silvia Boldeanu; [2018]
   Keywords : Brain-computer interface BCI ; Brain-machine interface BMI ; Virtual reality VR ; Motor imagery; Visual evoked potentials; Brain-to-brain communication;

   Abstract : Brain-computer interfaces (BCIs) blend methods and concepts researched by cognitive neuroscience, electrophysiology, computer science and engineering, resulting in systems of bi-directional information exchange directly between brain and computer. BCIs contribute to medical applications that restore communication and mobility for disabled patients and provide new forms of sending information to devices for enhancement and entertainment.

6. 5. 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).
