  1. 1. Dopaminergic and serotonergic modulation of cellular and locomotor network properties in the lamprey spinal cord

    Detta är en avhandling från Stockholm : Karolinska Institutet, Department of Neuroscience

    Sammanfattning : Motor activity is the basis for all behavior. It is therefore important to study the processes generating movement such as the neuronal networks in the spinal cord that generates and controls locomotion. The lamprey is used as a model system for the study of locomotion. Although, the lamprey is a simple vertebrate. LÄS MER

  2. 2. K+ channels and the regulation of synaptic transmission

    Detta är en avhandling från Stockholm : Karolinska Institutet, Department of Neuroscience

    Författare :Evanthia Nanou; Karolinska Institutet.; Karolinska Institutet.; [2009]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : Neuronal excitability is highly regulated by K+ channels that are activated by a voltage change across the plasma membrane or by a rise in intracellular Na+ or Ca2+ concentration. The main focus of this thesis has been to characterize the Na+-activated K+ (KNa) and the Ca2+-activated K+ (KCa) channels and to determine their role in regulating synaptic transmission in the lamprey spinal cord.

  3. 3. Mechanisms of rhythm generation in the lamprey locomotor network

    Detta är en avhandling från Stockholm : Karolinska Institutet, Department of Neuroscience

    Författare :Lorenzo Cangiano; Karolinska Institutet.; Karolinska Institutet.; [2004]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    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
