11. Neuromuscular adaptations to muscle fatigue during submaximal isometric contractions in man
Sammanfattning : 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. LÄS MER
12. On traumatic lesion to the spinal cord and dorsal spinal roots : factors influencing axonal regrowth across the border between the central and peripheral nervous system in the rat and man
Sammanfattning : Nerve cells are depending on their environment. Glial cells, astrocytes and oligodendrocytes in the central nervous system (CNS) make up a totally different milieu and characteristics than the distinguishing qualities of the peripheral nervous system (PNS), where the nerve cells are surrounded by Schwann cells.

13. The central cervical nucleus in the rat : studies on connectivity, function and chemical transmission
Sammanfattning : The central cervical nucleus (CCN) is a spinocerebellar cell group in the upper cervical spinal cord (rat: Cl-C3), that is known to receive a powerful primary afferent input from, the upper cervical spinal nerves (C 1-C4), originating mainly from muscle spindle afferents in deep dorsal neck muscles and from the ipsi- and contralateral vestibular nuclei. It projects to the cerebellar vermis bilaterally and to all the vestibular nuclei contralaterally. LÄS MER
14. Spinal motoneurones and the bulbospinal serotonininergic system in aged rats with behavioral deficits
Sammanfattning : The expression of neuropeptides, growth-related proteins and neurotrophin receptors were studied in motoneurons of young adult rats and in aged rats with symptoms of neuromuscular incapacities. Also studied were aging-related changes in the descending serotoninergic (5HT) bulbospinal system which constitutes a major afferent pathway to spinal motoneurons. LÄS MER
15. Proteins regulating vesicular docking and fusion : histochemical studies on their presence and regulation in endocrine, neuroendocrine and neuronal cells
Sammanfattning : Regulated transmitter release involves docking and fusion of transmitter-containing vesicles with the plasma membrane. Vesicular docking and fusion events are mediated by specific exocytotic proteins located at the vesicle membrane, in the cytoplasm or at the plasma membrane. LÄS MER
