  1. 16. Distribution and modulatory roles of neuropeptides and neurotransmitters in the Drosophila brain

    Författare :Lily Kahsai Tesfai; Åsa M. E. Winther; Ronald Strauss; Stockholms universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; central complex; locomotor behavior; co-transmitter; metabotropic receptor; metabolic stress; Neurobiology; Neurobiologi; zoologi; Zoology;

    Sammanfattning : The central complex is a prominent neuropil found in the middle of the insect brain. It is considered as a higher center for motor control and information processing. LÄS MER

  3. 17. Neuromodulation within a spinal locomotor network : role of metabotropic glutamate receptor subtypes

    Författare :Petronella Kettunen; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :mGluR1; mGluR5; spinal cord; modulation; glutamate; NMDA; leak channel; locomotion; endocannabinoids; lamprey.;

    Sammanfattning : The metabotropic glutamate receptors, mGluRs, are G-protein coupled receptors. They consist of eight cloned subtypes, which are divided into three groups depending on the amino acid sequence similarity, pharmacology and their signal pathways. LÄS MER

  4. 18. Optogenetic control of spinal microcircuits : insights into locomotor rhythm and pattern generation

    Författare :Martin Hägglund; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Mammalian locomotion is a complex task in which hundreds of muscles work together in a coordinated fashion. Neural networks in the spinal cord, known as central pattern generators (CPGs), carry all the components necessary to produce the cyclical pattern of muscle activity needed for locomotion. LÄS MER

  5. 19. Locomotor pattern generation in the spinal cord : studies in adult lamprey and zebrafish

    Författare :Riyadh Mahmood; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : The overall objective of this thesis is to characterize the mechanisms involved in the generation of locomotor activity in the spinal cord. To this end, we initially used the lamprey spinal cord to determine the transmitter phenotype of commissural interneurons (CINs). LÄS MER

  7. 20. Cytokines in the nervous system with emphasis on interleukin-1 receptor-mediated activity

    Författare :Mircea Oprica; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Interleukin-1 (IL-1) is one of the most important pro-inflammatory cytokines and plays a pivotal role in the neuroinflammation associated with certain forms of neurodegeneration, such as epilepsy, cerebral ischemia, trauma, and Alzheimer's disease (AD). Also, it was suggested that IL-1 is involved in physiological processes, namely modulation of sleep, glucose and lipid metabolism, and neuroendocrine regulation, as well as modulation of learning and memory.
