  1. 1. Development of functional asymmetries in young infants : A sensory-motor approach

    Författare :Erik Domellöf; Louise Rönnqvist; Jacqueline Fagard; Umeå universitet; []
    Nyckelord :SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; Laterality; development; handedness; human infant; stepping response; placing response; head turning; arm movement; reaching; kinematic parameters; intralimb coordination; Psychology; Psykologi;

    Sammanfattning : Human functional laterality, typically involving a right-sided preference in most sensory-motor activities, is still a poorly understood issue. This is perhaps particularly true in terms of what underlying mechanisms that may govern lateral biases, as well as the developmental origins and course of events. LÄS MER

  2. 2. To select one hand while using both : neural mechanisms supporting flexible hand dominance in bimanual object manipulation

    Författare :Anna Theorin; Roland Johansson; Fredrik Ullén; Umeå universitet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; object manipulation; bimanual coordination; action selection; cerebral cortex; functional laterality; humans; hand; magnetic resonance imaging; transcranial magnetic stimulation; electromyography; Physiology; Fysiologi; fysiologi; Physiology;

    Sammanfattning : 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. LÄS MER

  3. 3. Sensorimotor behavior in children born preterm and adolescents with Cerebral Palsy : Side preference, movement organization, and training

    Författare :Anna-Maria Johansson; Louise Rönnqvist; Erik Domellöf; Janette Atkinson; Umeå universitet; []
    Nyckelord :SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; prematurity; preterm; children; cerebral palsy; movement organization; movement performance; goal-directed; laterality; handedness; intelligence; cognition; synchronized metronome training; intervention; Psychology; psykologi;

    Sammanfattning : Preterm birth (< 37 complete gestation weeks, GWs) is the single most prominent risk factor for the development of cerebral palsy (CP). This is due to the immature physiological state of the preterm born infant which increases the risk of brain lesions. LÄS MER

  4. 4. The functional organisation of basal ganglia inputs

    Författare :Yvonne Johansson; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : The basal ganglia allow organisms to adjust their behaviour according to changes in their internal state or their environment. One essential prerequisite for the selection and execution of appropriate movements is the convergence of inputs from various sources, conveying sensory information, motor commands, reward value, and more.

  5. 5. Mind your Language, All Right? Performance-dependent neural patterns of language

    Författare :Helene van Ettinger-Veenstra; Maria Engström; Peter Lundberg; Thomas Karlsson; Anita McAllister; Karsten Specht; Linköpings universitet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Language ability; performance; fMRI; functional magnetic resonance imaging; Broca; Wernicke; temporal lobe; inferior frontal gyrus; reading; fluency; lateralization; lateralisation; right hemisphere; performance-dependent; neural activation;

    Sammanfattning : The main aim of this dissertation was to investigate the difference in neural language patternsrelated to language ability in healthy adults. The focus lies on unraveling the contributions of theright‐hemispheric homologues to Broca’s area in the inferior frontal gyrus (IFG) and Wernicke’s areain the posterior temporal and inferior parietal lobes.
