  1. 6. Analysis and modelling of grooming behaviour of mice

    University essay from KTH/Fysik

    Author : Wilhelm Sjöstedt; [2022]
    Keywords : Theoretical physics; Neuroscience; Embedded systems; Complex systems; Teoretisk fysik; Neurovetenskap; Inbyggda system; Komplexa system;

    Abstract : Mapping dynamical motion to neural brain activity is one of many challenges in the field of neuroscience. Further knowledge in this area could provide useful insights in fields such as medical treatment of brain disorders. READ MORE

  3. 7. Speaker verification: Advantages and limitations of a biologically inspired feature extractor

    University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

    Author : Maja Gajic; [2022]
    Keywords : Speaker verification; artificial neural network; ANN; feature extractor; Technology and Engineering;

    Abstract : Speaker verification is the process of verifying the identity of a person based on voice. This process usually encompasses the following steps: The speech signal is mapped into features using a feature extractor, these features are then classified using a post processor. READ MORE

  4. 8. Analysis of Brain Signals from Patients with Parkinson’s Disease using Self-Supervised Learning

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

    Author : Emma Lind; [2022]
    Keywords : Machine Learning; Self-supervised learning; Feature extraction; Parkinson’s Disease; Magnetoencephalography; Electroencephalogram; Maskininlärning; Självlärande inlärning; Särdragsextraktion; Parkinsons sjukdom; Magnetoencefalografi; Elektroencefalografi;

    Abstract : Parkinson’s disease (PD) is one of the most common neurodegenerative brain disorders, commonly diagnosed and monitored via clinical examinations, which can be imprecise and lead to a delayed or inaccurate diagnosis. Therefore, recent research has focused on finding biomarkers by analyzing brain networks’ neural activity to find abnormalities associated with PD pathology. READ MORE

  5. 9. A Single-Nucleus RNA Sequencing Analysis of HERVs and LINE1s in Alzheimer's and Parkinson's Disease

    University essay from Lunds universitet/Examensarbeten i bioinformatik

    Author : Stein Acker; [2022]
    Keywords : Biology and Life Sciences;

    Abstract : Transposable elements (TEs) are mobile genetic elements that make up roughly 50% of the human genome, with retrotransposons (or transposons which retrotranspose via an RNA intermediate) making up the vast majority of these elements. Recent studies have suggested that TEs could play a role in many neurological conditions, including ALS and dementia. READ MORE

  6. 10. Quantification of cerebral blood flow with 15O-water PET : A comparison study between PET/CT and PET/MR and two different blood sampling instruments

    University essay from Umeå universitet/Institutionen för fysik; Umeå universitet/Diagnostisk radiologi

    Author : Amanda Eriksson; [2021]
    Keywords : Cerebral Blood Flow; CBF; oxygen-15-labelled water; PET CT; PET MR; Quantification of CBF; Image Derived Input Function; IDIF; Blood Sampled Input Function; BSIF; Arterial Input Function; AIF; Tracer Kinetic Modelling; Single Tissue Compartmental Model; 1TCM;

    Abstract : Cerebral blood flow quantification is a vital diagnostic tool for disease monitoring and used for diagnosing a variation of pathological conditions. The human brain requires roughly about 20 % of the total cardiac output to sustain normal functioning, hence the perfusion of blood is an important factor to deliver oxygenated blood. READ MORE
