  1. 1. Neocortical interpretation of haptic and visual events across brain states: Electrophysiological investigations in sensory information processing

    Författare :Sofie Skårup Kristensen; Hjärnans sensorimotoriska funktioner; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Haptics; Visual; Multisensory; Cortical; Rodent; Neurophysiology; Tactile; Electrophysiology;

    Sammanfattning : This thesis delves into the complex architecture of dynamic sensory information processing in the neocortex. Specifically, it asks how primary sensory cortical regions are influenced by local and widespread cortical state changes. LÄS MER

  2. 2. Visual filtering in box jellyfish: A simple system

    Författare :Megan O'Connor; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Tripedalia cystophora; box jellyfish; Cnidaria; Chiropsella bronzie; visual filtering; visual systems; microspectrophotometry; vision; eyes;

    Sammanfattning : Unlike most jellyfish, box jellyfish (cubomedusae) are highly visually orientated. They are agile swimmers and use visual information to avoid obstacles and orientate themselves. LÄS MER

  3. 3. Signal identification for visual electrophysiological recordings. A comparison of signal analysis techniques and their application to clinical electrophysiology of vision

    Författare :Thomas Wright; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Visual Electrophysiology; Signal detection; Signal-to-Noise Ratio; multivariate analysis; spatial-temporal partial least-squares;

    Sammanfattning : Aims: The aim of this thesis was to investigate the use of objective methods for the analysis of visual electrophysiological recordings. Specifically can signal identification algorithms identify electrophysiological signals and can they be applied to improve clinical testing and analysis? Methods: Automated signal identification algorithms were applied to multifocal electroretinogram (mfERG) and visual evoked potential (VEP) recordings. LÄS MER

  4. 4. Retinal Vein Occlusion A clinical study of electrophysiology, certain prognostic factors and treatment

    Författare :Charlotte Lindberg; Lund Oftalmologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Ophtalmology; Oftalmologi; multifocal electroretinography vitrectomy; electroretinography; factor V Leiden; retinal vein occlusion; prognostic factors;

    Sammanfattning : The influence of the factor V Leiden mutation on the development of neovascular complications in central retinal vein occlusion was studied. The presence of the mutation was found to enhance the risk of developing neovascular complications almost threefold compared to in patients without the mutation. LÄS MER

  5. 5. Evaluation of the visual pathway with ERG, mfERG and mfVEP in inherited eye disorders

    Författare :Lotta Gränse; Lund Oftalmologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; multifocal ERG; Full-field ERG; multifocal VEP; Bothnia Dystrophy; Retinitis pigmentosa; Dominant optic atrophy; Leber`s hereditary optic neuropathy; Oftalmologi; Ophtalmology;

    Sammanfattning : This thesis will describe the clinical phenotypes, with emphasis on electrophysiology, in patients with different hereditary eye diseases and to further evaluate and modify the mfVEP technique for clinical use. Bothnia Dystrophy is a tapetoretinal disorder with a mutation in the RLBP1 gene. LÄS MER
