  2. 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

  4. 2. Neural correlates of individual differences in personality and intelligence : studies using an isochronous timing task and voxel based morphometry

    Author : Lea J Forsman; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : It is easy to imagine that humans have always noticed the differences between themselves and others and perhaps even speculated about the origins of these differences. The study of individual differences as a formal field encompasses variations in intelligence and personality as well as other dimensions. READ MORE

  5. 3. Brain imaging in extremely preterm infants : relations to perinatal factors and outcome

    Author : Georgios Alexandrou; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : The survival of extremely preterm infants has improved over the last decades along with the advances in perinatal care. These immature children are born at a vulnerable stage of brain development, before entering the third trimester of gestation, and are at an increased risk for brain injuries, atypical brain development and subsequent adverse neurodevelopment.

  6. 4. Brain Structure and Function in Adolescents with Atypical Anorexia Nervosa

    Author : Gaia Olivo; Helgi B. Schiöth; Christian Benedict; Jessica Mwinyi; Andreas Jansen; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MRI; functional MRI; fMRI; magnetic resonance imaging; neuroimaging; brain imaging; anorexia nervosa; eating disorders; neuroscience; adolescents; Medicinsk vetenskap; Medical Science; Neuroscience; Neurovetenskap;

    Abstract : Atypical anorexia nervosa (AAN) has a high incidence in adolescents, resulting in significant morbidity and mortality. The weight loss is generally less pronounced than that experienced in full-syndrome anorexia nervosa (AN), but the medical consequences can be as severe. READ MORE

  7. 5. When I show the Beatles then you say: ‛Ramones!’ : imaging semantic memory in Alzheimer’s disease and semantic dementia

    Author : Raffaella M Crinelli; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Elderly people contacting the health care system because of suspected dementia very often report word forgetfulness, a clinical condition referred as anomia, often one of the first signs of cognitive decline. Considering the complexity of human language it is no wonder that dementia disorders can affect language processing, which in its turn relies heavily on the intactness of the semantic memory system.
