  1. 21. Motor control in zebrafish : excitatory drive and developmental changes

    Författare :Sabine Görgens; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : An essential characteristic of human and animal life is the ability to move from one place to another, in order to survive in a complex environment. All the different forms of locomotion, like walking, swimming, crawling and flying, have one common feature: rhythmic and alternating movements of the body. LÄS MER

  3. 22. Who, when and how : electrophysiological studies on connectivity of striatal neurons

    Författare :Susanne Natalie Szydlowski; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : The nervous system has been studied in many ways and in many different organisms. Organisms that have a brain and mind or a simpler nervous system use it to sense the environment, process this sensory input and make appropriate decisions on how to act or interact with the environment.

  4. 23. Brain-derived neurotrophic factor and endocannabinoid functions in gabaergic interneuron development

    Författare :Paul Berghuis; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Formation of the cerebral cortex is controlled by tightly regulated processes: the proliferation and survival decisions of neural progenitors, radial and tangential migration of neuronal precursors, axon guidance and dendritic growth underpinning the formation of synapses. Patterning of the neocortex has been extensively studied and significant progress has been made in understanding the principles of cortical neuronal circuit formation. LÄS MER

  5. 24. Brain-derived neurotrophic factor in cerebral ischemia: a quantitative study on surviving and newly formed neurons

    Författare :Elin Gustafsson; Lund Klinisk fysiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; brain-derived neurotrophic factor; cerebral ischemia; neuronal survival; neurogenesis; hippocampus; striatum; immunocytochemistry; stereology; neuropsykologi; Neurologi; neurophysiology; neuropsychology; neurofysiologi; Neurology;

    Sammanfattning : This study explores the role of brain-derived neurotrophic factor (BDNF) for neuronal vulnerability and neurogenesis following cerebral ischemia in the rat. Cerebral ischemia results in selective neuronal cell loss in specific brain regions. We here demonstrate the rank order of vulnerability in two regions affected by global forebrain ischemia, i.

  7. 25. Neuromodulation shapes interneuron communication in the mouse striatum

    Författare :Matthijs Constantijn Dorst; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : A proper understanding of cognition relies on detailed knowledge about the functional connectivity within and between brain areas. The striatum is generally regarded as the input structure to the basal ganglia, a group of subcortical nuclei that have been demonstrated to be involved in motor function and reward, amongst other functions.
