11. 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.

Sammanfattning : Few children and adolescents reach the recommended levels of daily physical activity. This trend is evident in the countries examined in this thesis: Sweden and Spain. LÄS MER
13. Dopamine and the affective-cognitive gradient in the human striatum studied with multimodal brain imaging
Sammanfattning : Both dopamine and the dopamine rich brain area, striatum, have been linked to behaviors related to incentives, motor action, and associative processing. Most of the cortex sends projections to the striatum, these connections have been described as a gradient organization representing a repertoire of functional behaviors. LÄS MER
14. Postponement and Logistics Flexibility in Retailing
Sammanfattning : This dissertation addresses several general logistics problems in retailing regarding meeting a variety of customer demand and availability, efficiency and effectiveness in carrying inventory, and increased logistics flexibility. It builds upon the well-established supply chain principle of postponement, and argues for the benefits associated with it in tackling certain logistics challenges. LÄS MER
15. The architecture of the aging brain : functional reorganization, structural changes, and the role of dopamine receptors
Sammanfattning : Aging is associated with reorganization of functional brain architecture, potentially leading tocognitive decline in older age. However, the mechanisms responsible for alterations in functionalbrain architecture remain poorly understood. LÄS MER
