  1. 11. Oscillations and spike statistics in biophysical attractor networks

    Författare :Mikael Lundqvist; Anders Lansner; Arvind Kumar; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Attractor networks; computational neuroscience; cortex; datalogi; Computer Science;

    Sammanfattning : The work of this thesis concerns how cortical memories are stored and retrieved. In particular, large-scale simulations are used to investigate the extent to which associative attractor theory is compliant with known physiology and in vivo dynamics. LÄS MER

  3. 12. Neural Stem Cells - interaction with the brain and prospects for cell replacement therapy for Stroke

    Författare :Emanuela Monni; Neural stamcellsbiologi och terapi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Neural stem cells; human; fetus; cortex; striatum; stroke; transplantation; inflammation; fusion; reprogramming; chimera; heterokaryon;

    Sammanfattning : Stroke is an acute neurological condition and the leading cause of disability in adult humans. Treatments for efficient recovery are not available. The most common form of stroke results from the occlusion of the middle cerebral artery, which causes loss of brain parenchyma and many types of neurons as well as astrocytes and oligodendrocytes.

  4. 13. The effects of growth hormone on opioid-induced toxicity in vitro

    Författare :Erik Nylander; Mathias Hallberg; Alexis Bailey; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Growth hormone; opioids; methadone; morphine; ketobemidone; fentanyl; oxycodone; hydromorphone; insulin-like growth factor; cell viability; NG108-15; SH-SY5Y; hippocampus; cortex; Farmaceutisk vetenskap; Pharmaceutical Science;

    Sammanfattning : There is an ongoing opioid crisis in the United States that is portrayed by a large number of opioid-related deaths. Many of these cases involve commonly used prescription opioids, such as morphine, oxycodone, fentanyl, and methadone. This is concerning and highlights the problems associated with long-term opioid treatment. LÄS MER

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

    Författare :Tomás Mediavilla; Daniel Marcellino; Alexandra Badea; Umeå universitet; []
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

  7. 15. The prefrontal cortex and information processing : nitric oxide signaling studied in an animal model of schizophrenia

    Författare :Kim Fejgin; Göteborgs universitet; []
    Nyckelord :schizophrenia; nitric oxide; prepulse inhibition; phencyclidine; prefrontal cortex; cGMP; baclofen; cognition;

    Sammanfattning : The prefrontal cortex has been extensively linked to several cognitive domains that are severely compromised in schizophrenia. It has therefore become a key region for studies on the disabling cognitive dysfunction commonly observed in patients with schizophrenia. LÄS MER
