  1. 1. Impact of the autoencoder-based FINTA tractogram filtering method on brain networks in subjects with Mild Cognitive Impairment

    Master-uppsats, KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Författare :Teodor Pstrusiński; [2023]
    Nyckelord :Tractography; Autoencoder; diffusion MRI; Filtering; Graph; Connectome; Traktografi; Autoencoder; diffusions MRT; Filtrering; Graf; Konnektom;

    Sammanfattning : Diffusion Magnetic Resonance Imaging (dMRI) is a method for measuring molecular diffusion in biological tissue microstructure. This information can be used to predict the location and orientation of white matter fibers in the brain, a process known as tractography. LÄS MER

  3. 2. Computing network centrality measures on fMRI data using fully weighted adjacency matrices

    Kandidat-uppsats, Umeå universitet/Institutionen för datavetenskap

    Författare :Stefan Bränberg; [2016]
    Nyckelord :;

    Sammanfattning : A lot of interesting research is currently being done in the field of neuroscience, a recent subject being the effort to analyse the the human brain connectome and its functional connectivity. One way this is done is by applying graph-theory based network analysis, such as centrality, on data from fMRI measurements. LÄS MER

  4. 3. Dynamic fMRI brain connectivity : A study of the brain’s large-scale network dynamics

    Master-uppsats, Umeå universitet/Institutionen för strålningsvetenskaper; Umeå universitet/Institutionen för fysik

    Författare :Per Brantefors; [2016]
    Nyckelord :fMRI; dynamic functional connectivity; burst; burstiness; resting-state; temporal graph theory; networks; connectome; dynamic brain connectivity;

    Sammanfattning : Approximately 20% of the body’s energy consumption is ongoingly consumed by the brain, where the main part is due to the neural activity, which is only increased slightly when doing a demanding task. This ongoingly neural activity are studied with the so called resting-state fMRI, which mean that the neural activity in the brain is measured for participants with no specific task. LÄS MER
