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

    University dissertation from Stockholm : Karolinska Institutet, Dept of Neuroscience

    Author : Sabine Görgens; Karolinska Institutet.; Karolinska Institutet.; [2014]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Abstract : 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. READ MORE

  2. 2. Organization of the spinal locomotor network in zebrafish : Pattern of recruitment and origin of excitatory drive

    University dissertation from Stockholm : Karolinska Institutet, Dept of Neuroscience

    Author : Emma Eklöf Ljunggren; Karolinska Institutet.; Karolinska Institutet.; [2012]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Abstract : Locomotion is of vital importance for animals to survive in a complex environment. Locomotor movements are generated by neuronal networks that reside in the spinal cord and are composed of motoneurons and interneurons. READ MORE

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

    University dissertation from Stockholm : Karolinska Institutet, Dept of Neuroscience

    Author : Vanessa Ribeiro Caldeira; Karolinska Institutet.; Karolinska Institutet.; [2016]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Abstract : 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.

    Abstract : Neuromuscular Adaptations to Muscle Fatigue during Submaximal Isometric Contractions in Man Wolfgang N. Löscher Doctoral thesis from the Department of Neuroscience, Karolinska Institute,Stockholm,Sweden . During a sustained contraction, the force producing capacity of a muscle gradually decreases.

  5. 5. Generation and selection of motor behaviors neural circuits and endocannabinoid modulation

    University dissertation from Stockholm : Karolinska Institutet, Dept of Neuroscience

    Author : Jianren Song; Karolinska Institutet.; Karolinska Institutet.; [2015]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Abstract : 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. READ MORE
