6. The Influence of the Adenosine A1-receptor on Tubuloglomerular Feedback and Renin Release
Sammanfattning : The kidneys play a vital role in the maintenance of extracellular fluid and electrolyte balance and blood pressure. Adenosine, acting through the adenosine A1-receptor (A1R), and nitric oxide have been implicated in several of the regulatory mechanisms in the kidney. LÄS MER
7. 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.

8. Signaling via Orexin Receptors : A Pharmacological Study
Sammanfattning : The orexin receptors are a pair of newly discovered G-protein coupled receptors which are activated by the neuropeptides orexins and play a role in sleep/vigilance, apetite/metabolism and neuroendocrine regulation. On a cellular level receptor activation results in, to name but a few effects, elevation of intracellular calcium and depolarisation. LÄS MER
9. Context dependent adaptation of biting behavior in human
Sammanfattning : The focus of this thesis was to study an action that humans perform regularly, namely, to hold a morsel between the teeth and split it into smaller pieces. Three different issues related to this biting behavior were addressed: (1) the effect of reduced periodontal tissues on food holding and splitting behavior; (2) the behavioral consequences of performing different bite tasks with different functional requirements, i.

10. Structural and functional changes in the brain after surgically repaired median nerve injury
Sammanfattning : Despite the best available surgical repair, traumatic median nerve injury within the forearm typically causes lifelong impairment in hand function. This stems from an inadequate reinnervation of the nerves supporting sensory functions of the thumb, index and long finger, and of nerves supplying intrinsic hand muscles. LÄS MER
