  1. 1. Investigation of coherence between limbic structures in a rodent model of Parkinson's Disease

    Magister-uppsats, Umeå universitet/Institutionen för psykologi

    Författare :Love Zachrisson; [2021]
    Nyckelord :Parkinson’s Disease; PD; Psychosis; Schizophrenia; MK801; Synchrony; Coherence; 6-OHDA; Rats; 128-channel multi electrode array; MATLAB; LFP; Biomarker; ASSR; Steady-state response; Parkinsons sjudkom; PD; Psykos; Schizofreni; MK801; Synkronicitet; Koherens; 6-OHDA; Försökdsjur; Råttor; Elektrodimplantat; MATLAB; LFP; Biomarkör; ASSR; Steady-state responser;

    Sammanfattning : Parkinson’s Disease affects 10 million people worldwide, with 40% of patients developing an associated psychosis which has been identified by studies as the number one source of caretaker distress and is related to increased mortality. This is further complicated by the fact that typical antipsychotic drugs worsen many of the motor symptoms implicated in Parkinson’s Disease, with only one commercially available drug able to ameliorate both symptoms.

  3. 2. 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

  4. 3. Effect of Visual Load on Auditory Steady-State Response and Subjective Workload

    Master-uppsats, Stockholms universitet/Psykologiska institutionen

    Författare :Sandra Challma; [2019]
    Nyckelord :EEG; ASSR; Workload;

    Sammanfattning : Attention can be directed to different modalities such as vision and hearing. Crossmodal attention perspective consider the distribution of simultaneous attention through different senses. It is unclear to which degree task-irrelevant sounds are processed during crossmodal attention. LÄS MER

  5. 4. Does working memory capacity correlate with processing of auditory distractors under low versus high visual load?

    Kandidat-uppsats, Stockholms universitet/Psykologiska institutionen

    Författare :Rasmus Skarp; [2018]
    Nyckelord :working memory capacity; perceptual load; processing; ASSR; auditory steady state responses; EEG;

    Sammanfattning : Individuals with high working memory capacity (WMC) appear to be particularly good at focusing their attention (McCabe, Roediger, McDaniel, Balota, & Hambrick, 2010). Therefore, we studied the correlation between WMC and the ability to suppress neurological activity from a task-irrelevant stimulus. LÄS MER

  7. 5. Mutual fund performance in the Swedish premium system - Beyond the mean-variance framework

    Magister-uppsats, Lunds universitet/Nationalekonomiska institutionen

    Författare :Rasmus Håkansson; [2017]
    Nyckelord :PPM mutual fund performance higher moments Sharpe ratio; Business and Economics;

    Sammanfattning : This paper presents an evaluation of the Swedish pension system, using performance measures that accounts for higher moments of the distribution. The aim of this study is to analyze the relationship between the classical Sharpe ratio and more sophisticated measures, while specifically focusing on the outcome of the default fund in the system.
