  1. 11. Mechanisms of rhythm generation in the lamprey locomotor network

    Författare :Lorenzo Cangiano; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Animals propel themselves through space, swimming, walking or flying, by rhythmic oscillatory movements of their body and limbs. In vertebrates these movements are mainly generated by specialized neuronal circuits in the spinal cord, called central pattern generators (CPGs) for locomotion. LÄS MER

  3. 12. Interneuron diversity and function in the zebrafish locomotor circuits

    Författare :Eva Rebecka Björnfors; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : One of the most essential features of an animal’s behavior is the ability to navigate and interact with its environment. The generation of the locomotor rhythm is carried out by networks of neurons in the spinal cord, so called central pattern generators (CPGs). LÄS MER

  4. 13. EPHA4 and V2 interneurons in the mammalian locomotor network

    Författare :Line Lundfald; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Central pattern generators (CPGs) are neural networks that can execute halfautomated movements without supraspinal or sensory input. Hindlimb locomotion in mammals is dependent upon such a CPG which is located ventrally in the spinal cord lumbar enlargement. LÄS MER

  5. 14. Modulation of cellular mechanisms in a spinal locomotor network

    Författare :Jesper Tegnér; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Neuronal Network; Calcium Channels; Calcium-DependentPotassium Channels; Neuronal Oscillator; Neuromodulation; GABAg receptors; Lamprey; Locomotion; Spinal Cord; Computer Simulation;

    Sammanfattning : Neuronal networks generate behaviour. Thus, to understand behaviour requires information on how neuronal networks work in terms of their cellular components. The overall aim of this work has been to link processes occurring at an ionic level to the operation of a neural network specialized for undulatory locomotion. LÄS MER

  7. 15. Analysis of different forms of locomotor behavior in lamprey

    Författare :Salma Sanzida Islam; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Motor coordination; undulatory locomotion; postural corrections; spinal cord damage; lamprey;

    Sammanfattning : The ability to locomote, that is move actively in space, is characteristic of the animal kingdom. Many species are capable of different forms of locomotion. They include forward and backward locomotion, fast and slow progression, etc. LÄS MER
