3. 2. Transposable Elements in Neural Progenitor Cells

   Författare :Liana Fasching; Molekylär neurogenetik; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Transposable Elements; TRIM28; Epigenetic Regulation; Gene Expression; Neural Progenitor Cells;

   Sammanfattning : More than 90% of DNA does not code for proteins and for a long time these sequences were referred to as “junk DNA” due to their unknown purpose. With the advent of new technologies it is now known, that the non-coding part of the genome is of great importance for regulating gene expression and is therefore indispensable. LÄS MER

4. 3. Biomechanical methods and error analysis related to chronic musculoskeletal pain

   Sammanfattning : Background Spinal pain is one of humanity’s most frequent complaints with high costs for the individual and society, and is commonly related to spinal disorders. There are many origins behind these disorders e.g., trauma, disc hernia or of other organic origins. LÄS MER

5. 4. Tactile Sensory Control of Dexterous Manipulation in Humans

   Författare :Ingvars Birznieks; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Physiology; cutaneous sensibility; tactile afferents; fingertip force; grasp stability; human hand; manipulation; object shape; precision grip; sensorimotor control; coding; Fysiologi; Physiology; Fysiologi; fysiologi; Physiology;

   Sammanfattning : 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. LÄS MER

7. 5. Neural correlates of irrelevant speech

   Författare :Jens Gisselgård; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :;

   Sammanfattning : The irrelevant speech effect refers to a reduction in the immediate serial recall of lists of presented items when irrelevant auditory material is presented together with the items to be memorized. The ability to ignore irrelevant distractors is vital in increasingly demanding work environments and the capability to keep information in and out of mind is central in human information processing.
