1. Tactile Sensory Control of Dexterous Manipulation in Humans
University dissertation from Umeå : Integrativ medicinsk biologiAbstract : During dexterous manipulation with the fingertips, forces are applied to objects' surfaces. To achieve grasp stability, these forces must be appropriate given the properties of the objects and the skin of the fingertips, and the nature of the task. READ MORE

2. Optimizing and evaluation of a methacholine provocation test with application in occupational research
University dissertation from Uppsala : Acta Universitatis UpsaliensisAbstract : We have developed a methacholine provocation method, which detects bronchial responsiveness in more than 80% of healthy subjects. The method enables us to detect differences in bronchial responsiveness within the normal range. With this method FEV1 and Gaw had similar sensitivity in detecting small differences in bronchial responsiveness. READ MORE

3. Neurotransmission and functional synaptic plasticity in the rat medial preoptic nucleus
University dissertation from Umeå : IMBAbstract : Brain function implies complex information processing in neuronal circuits, critically dependent on the molecular machinery that enables signal transmission across synaptic contacts between neurons. The types of ion channels and receptors in the neuronal membranes vary with neuron types and brain regions and determine whether neuronal responses will be excitatory or inhibitory and often allow for functional synaptic plasticity which is thought to be the basis for much of the adaptability of the nervous system and for our ability to learn and store memories.

4. To select one hand while using both neural mechanisms supporting flexible hand dominance in bimanual object manipulation
University dissertation from Umeå : Umeå universityAbstract : In daily activities, the brain regularly assigns different roles to the hands dependingon task and context. Yet, little is known about the underlying neural processes. Thiscertainly applies to how the brain, where each hemisphere primarily controls onehand, manages the between-hand coordination required in bimanual objectmanipulation. READ MORE

5. The Influence of the Adenosine A1-receptor on Tubuloglomerular Feedback and Renin Release
University dissertation from Uppsala : Acta Universitatis UpsaliensisAbstract : 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. READ MORE
