  1. 1. Temporal dynamics of brain plasticity : characterizing brain structural changes during skill acquisition

    Author : Tomás Mediavilla; Daniel Marcellino; Alexandra Badea; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Motor learning; brain plasticity; structural plasticity; magnetic resonance imaging; voxel-based morphometry; tractography; connectivity; motor cortex; posterior parietal cortex; cerebellum; vesicular glutamate transporter;

    Abstract : Traditionally, structural plasticity in the human brain has been considered to follow a linear or asymptotic increase over the course of training. However, recent studies using structural MRI revealed transient increases in grey matter volume (GMV) with learning. READ MORE

  2. 2. Brain morphology and behaviour in the guppy (Poecilia reticulata) : Effects of plasticity and mosaic brain evolution

    Author : Stephanie Fong; Niclas Kolm; Björn Rogell; Stephen Montgomery; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; brain plasticity; cognition; reversal learning; spatial learning; directed selection; mosaic brain; heritability; brain morphology; boldness; relative telencephalon size; inhibitory control; detour task; Poecilia reticulata; etologi; Ethology;

    Abstract : Understanding how brains have evolved and subsequently culminated in the huge variation in brain morphology among contemporary vertebrate species has fascinated researchers for many decades. It has been recognized that brain morphology is both genetically and environmentally determined. READ MORE

  3. 3. Brain plasticity and hand function

    Author : Anders Björkman; Malmö Handkirurgi; []
    Keywords : 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;

    Abstract : 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. READ MORE

  4. 4. Plasticity and Inflammation following Traumatic Brain Injury

    Author : Anders Hånell; Niklas Marklund; Lars Hillered; Nikolaus Plesnila; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Traumatic Brain Injury; plasticity; inflammation; Nogo receptor; EphA4; IL-1β; Neurosurgery; Neurokirurgi; Neuroscience; Neurovetenskap;

    Abstract : Traumatic Brain Injury (TBI) mainly affects young persons in traffic accidents and the elderly in fall accidents. Improvements in the clinical management have significantly improved the outcome following TBI but survivors still suffer from depression, memory problems, personality changes, epilepsy and fatigue.

  5. 5. Glioblastoma heterogeneity and plasticity : Investigating the roles of BMP4 and SOX2

    Author : Erika Dalmo; Bengt Westermark; Fredrik J. Swartling; Lene Uhrbom; Ana Martin-Villalba; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Glioblastoma; SOX2; BMP4; senescence; plasticity; Oncology; Onkologi; Medicinsk vetenskap; Medical Science; Biology with specialization in Molecular Biology; Biologi med inriktning mot molekylärbiologi;

    Abstract : The malignant primary brain tumor glioblastoma has a dismal prognosis and is distinguished by its heterogeneous character. Current treatment with surgical resection, radiotherapy and adjuvant chemotherapy with the alkylating agent temozolomide does not provide a cure, but simply prolongs survival by a few months.
