  1. 1. Infrared Neural Modulation: Photothermal Effects on Cortex Neurons Using Infrared Laser Heating

    Författare :Qingling Xia; Tobias Nyberg; Björn Granseth; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; neural modulation; infrared laser; in - vitro experiment; multi - electrode arrays MEA ; heating model; temperature; neural networks; infrared neural inhibition INI ; hyperexcitation;

    Sammanfattning : It would be of great value to have a precise and non-damaging neuromodulation technique in the field of basic neuroscience research and for clinical treatment of neurological diseases. Infrared neural modulation (INM) is a new modulation modality developed in the last decade, which uses pulsed or continues infrared (IR) light with a wavelength of 1200 to 2200 nm to directly alter neural signals.

  3. 2. Discordant Neural Xenografting: Analysis and Modulation of Immune Responses

    Författare :Lena Cecilia Larsson; Neurobiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; neuropsykologi; Neurologi; neurofysiologi; neurophysiology; neuropsychology; Neurology; immunosuppression; immunology; xenograft; pig; Parkinson s disease; intracerebral transplantation;

    Sammanfattning : Transplantation of embryonic human neural tissue can restore function in patients with Parkinson’s disease, but there is a severe shortage of donor tissue which limits the applicability of the technique. Embryonic neural tissue from other species, xenogeneic tissue, would provide a readily accessible donor tissue with the potential to help patients if the immunological reactions in the host could be prevented.

  4. 3. Neurogenesis and gliogenesis after focal brain ischemia. Modulation by enriched environment and exercise

    Författare :Mila Komitova; Göteborgs universitet; []
    Nyckelord :astrocyte; hippocampus; neural progenitor cells; neural stem cells; neurogenesis; neurotrophins; rat; regeneration; rehabilitation; stroke;

    Sammanfattning : New neurons are formed from dividing neural stem cells in restricted areas in the adult mammalian brain: the dentate gyrus of the hippocampal formation (DG) and the forebrain subventricular zone (SVZ). New glia also form constitutively and seem to be important for neuronal function. LÄS MER

  5. 4. Neural control of standing posture

    Författare :Craig Tokuno; Andrew Cresswell; Alf Thorstensson; Marc Carpenter; Thomas Sinkjær; Gymnastik- och idrottshögskolan; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Medicin Teknik; Medicine Technology; Posture; motor cortex; electromyography; kinematics; H-reflex; pre-synaptic inhibition; transcranial magnetic stimulation;

    Sammanfattning : When humans are asked to stand normally, they are not completely motionless. Rather, small amounts of body movement, termed postural sway, can be observed. Although the postural sway of standing has been well described, the manner in which this sway is neurally controlled and its influence in tasks involving postural re-stabilization are not known.

  7. 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 :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.
