  2. 11. A sensory role for the cruciate ligaments : regulation of joint stability via reflexes onto the γ-muscle-spindle system

    Author : Per Sjölander; Håkan Johansson; Uwe Windhorst; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Joint afferent; Mechanoreceptor; Cruciate ligament; Fusimotor neuron; reflex; muscle spindle afferent; motor control; cat;

    Abstract : Reflex effects evoked by graded electrical stimulation of the posterior articular nerves (PAN) of the ipsi- and contralateral knee joints were investigated using both micro-electrode recordings from 7 - motoneurones and recordings from single muscle muscle spindle afferents. Spindle afferent responses were also recorded using natural stimulation of different types of receptors, to elucidate if the articular reflexes onto the y -motoneurones were potent enough to significantly alter the muscle spindle afferent activity.

  4. 12. Brain functional near infrared spectroscopy in human infants : cerebral cortical haemodynamics coupled to neuronal activation in response to sensory stimulation

    Author : Marco Bartocci; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Near infrared spectroscopy; newborn; infant; brain; sensory stimulation; cortical activation;

    Abstract : The assessment of cortical activation in the neonatal brain is crucial in the study of brain development, as it provides precious information for how the newborn infant processes external or internal stimuli. Thus far functional studies of neonates aimed to assess cortical responses to certain external stimuli are very few, due to the lack of suitable techniques to monitor brain activity of the newborn.

  5. 13. Pain, Touch, and Decision Making : Behavioral and Brain Responses to Affective Somatosensory Stimulation

    Author : Lina Koppel; India Morrison; Daniel Västfjäll; Gustav Tinghög; Johannes Haushofer; Linköpings universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Abstract : Stimulation of sensory nerves can give rise to powerful affective experiences. Noxious stimuli can give rise to pain, an unpleasant experience which, in turn, causes suffering and constitutes a major societal burden. Touch, on the other hand, can feel pleasant and plays an important role in social relationships and well-being. READ MORE

  6. 14. Tactile Sensory Control of Dexterous Manipulation in Humans

    Author : Ingvars Birznieks; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Physiology; cutaneous sensibility; tactile afferents; fingertip force; grasp stability; human hand; manipulation; object shape; precision grip; sensorimotor control; coding; Fysiologi; Physiology; Fysiologi; fysiologi; Physiology;

    Abstract : During dexterous manipulation with the fingertips, forces are applied to objects' surfaces. To achieve grasp stability, these forces must be appropriate given the properties of the objects and the skin of the fingertips, and the nature of the task. READ MORE

  7. 15. Nerve injury induced pain and spinal cord stimulation

    Author : Camilla Ultenius; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Neuropathic pain;

    Abstract : Chronic neuropathic pain caused by injury to or disease in the nervous system is relatively common and results in major suffering, poor quality of life and incapacity. Such pain is a therapeutic challenge because a considerable portion of the patients fails to benefit from pharmacotherapy. READ MORE
