3. 2. Brain plasticity and hand function

   Författare :Anders Björkman; Malmö Handkirurgi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; traumatologi; Neurology; neuropsychology; neurophysiology; Neurologi; neuropsykologi; neurofysiologi; Kirurgi; ortopedi; traumatology; Surgery; Medicin människa och djur ; Medicine human and vertebrates ; hand function; nerve injury; brain plasticity; orthopaedics;

   Sammanfattning : The aim of this thesis was to investigate the effects of cortical reorganisational changes following experimental deafferentation and peripheral nerve injury and apply the concept of brain plasticity to enhance sensory re-education following peripheral nerve injury and repair in the hand. In the first two papers the effects on hand function of contralateral deafferentation was investigated. LÄS MER

4. 3. Human brain function evaluated with rCBF-SPECT : memory and pain related changes and new diagnostic possibilities in Alzheimer’s disease

   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; brain imaging; rCBF; SPECT; early diagnosis; brain atlas; HMPAO; Alzheimer´s disease; Whiplash; neuropsychological function; episodic memory; Diagnostic radiology; Diagnostisk radiologi;

   Sammanfattning : The aim of this doctoral thesis was to study the influence of memory, pain, age and education on the regional cerebral blood flow (rCBF), i.e. brain function, in early Alzheimer's disease (AD) and in chronic neck pain patients in comparison to healthy controls and in healthy elderly per se.

5. 4. Telomeres and the brain : an investigation into the relationships of leukocyte telomere length with functional and structural attributes of the brain

   Författare :Mikael Wikgren; Karl-Fredrik Norrback; Rolf Adolfsson; Göran Roos; Thomas Karlsson; Brenda Penninx; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; APOE; aging; atrophy; brain; cognition; cortisol; depression; hippocampus; HPA axis; MRI; stress; telomere length; white matter hyper-intensities.;

   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

7. 5. Train your brain : updating, transfer, and neural changes

   Författare :Erika Dahlin; Lars Nyberg; Anna Stigsdotter Neely; Torkel Klingberg; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; cognitive training; executive functioning; transfer; fMRI; brain system; young adults; elderly; practice; neural correlates; individual differences; Experimental brain research; Experimentell hjärnforskning; Cognitive science; Kognitionsforskning; fysiologi; Physiology;

   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.
