  2. 1. Post activation potentiation : Modulating factors and mechanisms for muscle performance

    Author : Paulo Gago; Ekblom Maria; Anton Arndt; Nicola Maffiuletti; Gymnastik- och idrottshögskolan; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Potentiation; twitch; triceps surae; knee angle; stiffnes; length changes; electromechanical delay; Medicin Teknik; Medicine Technology;

    Abstract : Introduction: Acute enhancements of muscle contractile properties and performance subsequent to a maximal or near maximal conditioning contraction are often termed post activation potentiation (PAP). Although still controversial, PAP is commonly linked to enhancements in the myosin regulatory light chain phosphorylation, leading to improvements in the excitation–contraction coupling. READ MORE

  4. 2. Plasticity in mice nociceptive spinal circuits -role of cell adhesion molecules

    Author : Jonas Thelin; Neurofysiologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Long term-potentiation; Cell adhesion molecule; Pain; Somatosensory imprinting; Medicin människa och djur ; Medicine human and vertebrates ; Nociceptive withdrawal reflex; Species differences; Central sensitisation; Mouse strains; Spinal cord;

    Abstract : Introduction: To understand the function of the genes and their products in the pain system, studies will have to deal with complex issues related to intercellular communication, e.g. plasticity in neuronal networks. READ MORE

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

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

    Abstract : 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. READ MORE

  6. 4. Modulatory effects and interactions of substance P, dopamine and 5-HT in a neuronal network

    Author : Erik Svensson; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Lamprey; spinal cord; neuromodulation; substance P; 5-HT; dopamine;

    Abstract : The spinal neuronal network that generates the locomotor rhythm in lamprey contains excitatory and inhibitory interneurons, reticulospinal inputs from the brainstem, and motor neurons. In this thesis, I have studied how the spinal locomotor network cart be modulated by a tachykinin, dopamine and 5- HT that are co-localized in midline neurons situated below the central canal.

  7. 5. On the role of metabotropic glutamate receptors in motor control : analysis of synaptic, cellular and network properties

    Author : Patrik Krieger; Karolinska Institutet; Karolinska Institutet; []
    Keywords : calcium channels; lamprey; locomotion; metabotropic glutamate receptors; neuronal network; spinal cord; synaptic transmission;

    Abstract : The organization of neurons into neuronal networks is a basic feature of the central nervous system. An understanding of the function of neuronal networks requires knowledge on both synaptic connectivity and cellular properties. READ MORE
