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

    Master-uppsats, Uppsala universitet/Institutionen för informationsteknologi

    Författare :Peipei Han; [2020]
    Nyckelord :;

    Sammanfattning : 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.

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

    Master-uppsats, SLU/Dept. of Clinical Sciences

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

    Sammanfattning : 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. LÄS MER

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

    Kandidat-uppsats, Stockholms universitet/Psykologiska institutionen

    Författare :Jenny Arctaedius; [2020]
    Nyckelord :Attention; Auditory Processing; Perceptual load; ASSRs; Filtering; EEG;

    Sammanfattning : 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). LÄS MER
