Anode break excitation in single myelinated nerve fibres.
It has long been considered that anode break excitation (ABE) is not elicitable in normal isolated nerve fibres. Quite recently, one of the authors (Konishi, 1957) found that it was due to weakness of the current applied and that, if a strong current (more than ten times the rheobase) was used, a single fibre, too, gave readily ABE. The present paper deals chiefly with threshold conditions for ...
متن کاملOn the capacity current in myelinated nerve fibres.
Different equivalent circuits are presented to describe the capacity current, Ic, of potential-clamped Ranvier nodes. The corresponding transfer functions are discussed in examining the influence of the involved parameters on size and time course of Ic. The following results were obtained: i. The duration and the amplitude of Ic increased with increasing membrane capacity. ii. The amplitude of ...
متن کاملNociceptors and warm receptors innervated by C fibres in human skin.
The properties of 125 C fibre units recorded from the peripheral nerves of conscious man were studied. On the basis of receptive field properties and responses to natural stimulation, 120 of the units were classified as polymodal C nociceptors. Five of the units were identified as specific C warm receptors. In contrast to the polymodal nociceptors, which often had comparatively large and comple...
متن کاملAtrophy of myelinated nerve fibres in the retina in optic neuritis.
Atrophy of the nerve fibres in the retina visible by direct ophthalmoscopy using red-free illumination, together with corresponding scotomata in the visual fields, signified retrograde degeneration of retinal nerve fibres from multiple sclerosis. Defects in medullated retinal nerve fibres were continous with arcuate nerve fibre bundle defects. These myelin defects exemplify secondary demyelinat...
متن کاملNeurogenic muscular atrophy and low density of large myelinated fibres of sural nerve in chorea-acanthocytosis.
In three cases of chorea-acanthocytosis (acanthocytosis and neurological disease, or familial degeneration of the basal ganglia with acanthocytosis), biopsies of short peroneal muscles and sural nerves were studied histologically. The muscles showed groups of atrophic fibres with clumping of sarcolemmal nuclei in all cases. It was concluded that neurogenic muscular atrophy should be included as...
