  2. 6. Defense-related inhibition of sympathetic nerve activity: Insights from neuroimaging and monozygotic twins on related cortical processes and clinical potential

    Author : John Jonsson Eskelin; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; microneurography; MEG; EEG; MRI; blood pressure; defence reaction; cortical autonomic network;

    Abstract : This thesis investigates a physiological phenomenon observed in the peripheral sympathetic nervous system in response to various stressors and tries to bring it closer to clinical research. Sudden surprising stimulation can evoke a transient inhibition of sympathetic nerve activity to blood vessels in the human body which is also predictive of the blood pressure response. READ MORE

  4. 7. Functional organisation and population behaviour of human peripheral nerve fibres : a microneurography study

    Author : Gung Wu; Karolinska Institutet; Karolinska Institutet; []
    Keywords : human somatosensory system; nerve organisation; peripheral nerve; cutaneous mechanoreceptors; skin innervation; microneurography; microelectrode;

    Abstract : With regard to the intraneural organisation of peripheral nerves findings obtained from previous anatomical and physiological studies appear to be controversial. The conventional concept seems to be that peripheral nerves lack a detailed topographical organisation. READ MORE

  5. 8. 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

  6. 9. Human periodontal mechanoreceptors : functional properties and role in jaw motor control

    Author : Skjalg E Johnsen; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Periodontal mechanoreceptors signal information about tooth loads to the central nervous system and are considered to be important for the control of oral motor behaviors, like biting and chewing. Surprisingly, very little is known about the functional properties of periodontal mechanoreceptors at posterior teeth. READ MORE

  7. 10. New functional and anatomical aspects of the organisation of human peripheral nerve

    Author : Rolf Ekedahl; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Somatosensory system; Peripheral nerve organisation; somatotopy; modalitysegregation; cutaneous mechanoreceptors; Human.Huddinge 1996;

    Abstract : The functional topography of peripheral nerves has been studied by various indirect electrophysiological and histological methods. Even though some studies have suggested the presence of a somatotopical arrangement of nerve fibres, the prevailing view is that a random distribution of nerve fibres develops in the nerve due to the repeated rearrangement of nerve fascicles along their centripetal course.
