1. 11. Functional organisation and population behaviour of human peripheral nerve fibres : a microneurography study

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

   Sammanfattning : 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. LÄS MER

3. 12. On the relation between nerve fibres and glial cells

   Författare :Carl Bjartmar; W. F. Blakemore; Linköpings universitet; []
   Nyckelord :MEDICINE; MEDICIN;

   Sammanfattning : The general aim of this study is to generate knowledge on the normal axo-glial relations in developing and adult vertebrate white matter. CNS and PNS specimens from developing and mature rats and from chickens of various ages were analysed through electron microscopy of single and serial sections, or through immunohistochemistry.

4. 13. New functional and anatomical aspects of the organisation of human peripheral nerve

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

   Sammanfattning : 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.

5. 14. Structure and function of trigeminal primary sensory neurons after peripheral nerve injury

   Författare :Ulf Bongenhielm; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :ankyrinG; chronic constriction injury; electron microscopy; electrophysiology; hyperexcitability; immunocytochemistry; inferior alveolar nerve; in situ hybridisation; nerve injury; neuroma; SNS PN3; sodium channel; trigeminal ganglion;

   Sammanfattning : Iatrogenic injuries to branches of the trigeminal nerve are common during surgical procedures in the jaws and teeth, and as the repercussion of facial fractures or certain pathologies. A portion of these patients are left with disturbed sensory functions, and some with unpleasant abnormal sensations, including pain. LÄS MER

7. 15. Nerve lesions in pharynx : an aetiology of obstructive sleep apnoea

   Författare :Danielle Friberg; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :;

   Sammanfattning : "Heavy snorers disease" is defined as the progression from habitual snoring to obstructive sleep apnoea (OSA). Apart from a significant weight gain, the aetiology underlying progression to a collapse of the upper airways during inspiration and sleep remains unclear. LÄS MER
