  1. 1. Experimental studies of spinal mechanisms associated with muscle fatigue

    Author : Ivana Kalezic; Högskolan i Gävle.; Umeå universitet.; [2004]
    Keywords : Muscle fatigue; Monosynaptic reflex; Presynaptic Inhibition; Recurrent Inhibition; Fusimotor System; Fos-immunoreactivity; Referral Pain; kirurgi; Surgery; muscle fatigue; monosynaptic reflex; presynaptic inhibition; recurrent inhibition; fusimotor system; referral pain;

    Abstract : Muscle fatigue is ubiquitous in every day life.Muscle fatigue might be considered as an altered state of motor behaviour, which impairs motor performance. By contrast, muscle fatigue could also be considered a positive phenomenon, which protects muscle tissue from damage that might be incurred to it by overuse. READ MORE

  2. 2. On spinal mechanisms for reflex control in man modulation of Ia-afferent excitation with changes in muscle length, activation level and fatigue

    University dissertation from Stockholm : Karolinska institutet

    Author : Maria M. Nordlund; GIH. Gymnastik- och idrottshögskolan; Karolinska Institutet.; Karolinska Institutet.; [2004]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Medicin Teknik; Medicine Technology; Electromyography; eccentric; concentric; presynaptic inhibition; H-reflex; central fatigue; twitch interpolation; muscle spindle; Electromyography; eccentric; concentric; presynaptic inhibition; H-reflex; central fatigue; twitch interpolation; muscle spindle;

    Abstract : To control muscle force, neural activation has to take alterations in muscle mechanics into account. This thesis assesses modulations in excitatory efficacy of Ia-afferents during muscle length changes at different levels of voluntary activation and during fatigue. READ MORE

    Abstract : Asthma is one of the commonest diseases in industrialized countries. The cause and mechanisms of !he disorder are still not fully unden;tood, al!hough it is known that inflammation in !he airways plays an important role. Inflammatory mediators, e.g. READ MORE

  4. 4. Afferent input to midbrain dopamine neurones and its modulation : an electrophysiological study i vitro

    University dissertation from Stockholm : Karolinska Institutet, Department of Physiology and Pharmacology

    Author : Pernilla Grillner; Karolinska Institutet.; Karolinska Institutet.; [1999]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; dopamine neurones; synaptic transmission; NMDA receptors; L-type Ca2 channels; presynaptic inhibition; metabotropic glutamate receptors; muscarine; nicotine;

    Abstract : Dopamine (DA) neurones of the ventral mesencephalon are involved in the control of reward related behaviour, cognitive functions and motor performances, and provide a critical site of action for major categories of neuropsychiatric drugs, such as antipsychotic agents, dependence producing drugs and anti-Parkinson medication. The midbrain DA neurones are mainly located in the substantia nigra pars compacta (SNPC) and the ventral tegmental area (VTA). READ MORE

  5. 5. Neuromodulation via endocannabinoids and nitric oxide in the lamprey spinal cord

    University dissertation from Stockholm : Karolinska Institutet, Department of Neuroscience

    Author : Alexandros Kyriakatos; Karolinska Institutet.; Karolinska Institutet.; [2009]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Abstract : The overall objective of this thesis is to increase our understanding of neural networks generating locomotion. These networks called Central Pattern Generators (CPG), are localized in the spinal cord and can generate the basic locomotor pattern in the absence of sensory or supraspinal inputs. READ MORE
