  2. 6. Neural circuits engaged in mastication and orofacial nociception

    Author : Tuija Athanassiadis; K-G Westberg; Sten Grillner; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; rhythmical jaw movements; central pattern generator; trigeminal system; rabbit; Rat; c-Fos; nociceptors; muscle pain; muscle spindle afferents; glutamate; Neurophysiology; Neurofysiologi; fysiologi; Physiology;

    Abstract : A deeper understanding of both movement control and the effects of nociceptor inputs on our motor systems is critical for proper clinical diagnosis of musculo-skeletal dysfunctions and for development of novel rehabilitation schemes. In the jaw system, masticatory movements are produced by a central pattern generator (CPG) located in the brainstem. READ MORE

  4. 7. Discharges in human muscle afferents during manual tasks

    Author : Michael Dimitriou; Benoni Edin; Roger Lemon; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; motor control; muscle spindle; Golgi tendon organ; muscle afferent; microneurography; proprioception; sensorimotor; fusimotor; hand; forward model; ; Neuroscience; Neurovetenskap;

    Abstract : Muscle spindles are complex sensory organs that have been strongly implicated in the control and perception of movements. Human muscle spindles in relaxed muscles behave as stretch receptors, responding to the length and velocity of their parent muscles. READ MORE

  5. 8. Experimental studies of spinal mechanisms associated with muscle fatigue

    Author : Ivana Kalezic; Vito Enrico Pettorossi; Umeå universitet; []
    Keywords : muscle fatigue; monosynaptic reflex; presynaptic inhibition; recurrent inhibition; fusimotor system; Fos-immunoreactivity; referral pain; kirurgi; Surgery;

    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

  6. 9. Neuromuscular adaptations to muscle fatigue during submaximal isometric contractions in man

    Author : Wolfgang N Löscher; Karolinska Institutet; Karolinska Institutet; []
    Keywords : isometric; electromyography; tremor; H-reflex; twitch; motoneuron; recruitment; la-afferents; recurrent inhibition; central fatigue; excitatory drive; gastrocnemius; soleus; triceps surae; tendon vibration; ischemia; Renshaw cellStockholm 1995;

    Abstract : During a sustained contraction, the force producing capacity of a muscle gradually decreases. In order to maintain a constant force output, the neuromuscular system has to adapt to the contractile fatigue process. READ MORE
