1. Telomeres and the brain : an investigation into the relationships of leukocyte telomere length with functional and structural attributes of the brain
Sammanfattning : Telomeres are the outermost parts of linear chromosomes. They consist of tandemly repeated non-coding short nucleotide sequences (TTAGGG in all vertebrates), in humans spanning over the last 2 to 15 kilobase pairs of the chromosome. Due to the end-replication problem, telomeres shorten with each cellular division. LÄS MER
2. Train your brain : updating, transfer, and neural changes
Sammanfattning : An initial aim of this thesis was to determine whether training of a specific executive function (updating) produces improvements in performance on trained and transfer tasks, and whether the effects are maintained over time. Neural systems underlying training and transfer effects were also investigated and one question considered is whether transfer depends on general or specific neural overlap between training and transfer tasks.

3. Temporal dynamics of brain plasticity : characterizing brain structural changes during skill acquisition
Sammanfattning : Traditionally, structural plasticity in the human brain has been considered to follow a linear or asymptotic increase over the course of training. However, recent studies using structural MRI revealed transient increases in grey matter volume (GMV) with learning. LÄS MER
4. Möjlighet till aktivitet och delaktighet utanför hemmet för personer med förvärvad hjärnskada
Sammanfattning : Det övergripande syftet med denna avhandling var att öka kunskapen om möjlighet till aktivitet och delaktighet utanför hemmet för personer i yrkesverksam ålder med förvärvad hjärnskada (FHS).Studie I syftade till att utforska och beskriva hur personer med FHS erfar engagemang i aktiviteter utanför hemmet.

5. Reality-based brain-computer interaction
Sammanfattning : Recent developments within human-computer interaction (HCI) and cognitive neuroscience have come together to motivate and enable a framework for HCI with a solid basis in brain function and human reality. Human cognition is increasingly considered to be critically related to the development of human capabilities in the everyday environment (reality). LÄS MER
