  1. 36. Generation and selection of motor behaviors neural circuits and endocannabinoid modulation

    Författare :Jianren Song; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : The generation of basic motor behavior relies on the activation of spinal neuronal networks called central pattern generators (CPGs). Descending drive from higher brain areas activates the spinal CPG to generate motor behavior. In the face of changes in the environment, animals make constant motor behavioral selection. LÄS MER

  3. 37. 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

  4. 38. Neurotoxicity of methylmercury : analysis of molecular mechanisms and behavioral alterations

    Författare :Elisabetta Daré; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Apoptosis; oxidative stress; neurons; glia; rats; dopamine; locomotion; learning and memory; environmental pollutants;

    Sammanfattning : MethyImercury (MeHg) is a global pollutant that is toxic for the nervous system, especially during development. Contaminated fish is the main route of human exposure. Recent studies have indicated that neurological alterations in humans may occur even after exposure to fairly low levels of MeHg. LÄS MER

  5. 39. Molecular coding and physiological roles of excitatory neurons in motor control

    Författare :Vanessa Ribeiro Caldeira; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Locomotion is a complex motor action that provides humans and other animals with the ability to move through the environment. In vertebrate locomotion, supraspinal centers convey the initiating or terminating command signals to the spinal cord which in turn generates the rhythm and pattern of muscle activities underlying locomotor activity.

  7. 40. Functional role of cerebrospinal fluid contacting cells in the spinal cord and hypothalamus

    Författare :Elham Jalalvand; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Cerebrospinal fluid-contacting (CSF-c) cells are found lining the walls of the central canal and the ventricles throughout the vertebrate phylum, but their function has remained elusive. The aim here was to investigate the physiological role of CSF-c cells in the spinal cord and hypothalamus. LÄS MER
