Excitation block in a nerve fibre model owing to potassium-dependent changes in myelin resistance.
The myelinated nerve fibre is formed by an axon and Schwann cells or oligodendrocytes that sheath the axon by winding around it in tight myelin layers. Repetitive stimulation of a fibre is known to result in accumulation of extracellular potassium ions, especially between the axon and the myelin. Uptake of potassium leads to Schwann cell swelling and myelin restructuring that impacts the electr...
متن کاملAcutance, an objective measure of retinal nerve fibre image clarity.
BACKGROUND/AIMS The interpretation of high contrast retinal nerve fibre layer (RNFL) images in glaucoma can be confounded by the presence of image blur; it can be difficult to discern diffuse axon loss in a poor quality image. One solution is to provide an objective measure of the image quality based on features in the image other than the RNFL. In this study the authors have developed an objec...
متن کاملAn Analysis of Fibre-size in the Human Optic Nerve.
DATA on the fibre-size " spectrum " in the optic pathways must form an essential anatomical preliminary to electro-physiological studies of the visual neural system. Extensive studies on peripheral nerves have brought to light some of the factors on which the differences of calibre of nerve fibres appear to be based. Studies of fibre-size in the central nervous system have been carried out by H...
متن کاملPotassium leakage during the apoptotic degradation phase.
The subcellular compartmentalization of ions is perturbed during the process of apoptosis. In this work, we investigated the impact of K+ on the apoptotic process in thymocytes and T cell hybridoma cells. Irrespective of the death-inducing stimulus (glucocorticoids, topoisomerase inhibition, or Fas-crosslinking), a significant K+ outflow was observed during apoptosis, as determined on the singl...
متن کاملAn active leakage-injection scheme applied to low-voltage SRAMs
An active leakage-injection scheme (ALIS) for lowvoltage (LV) high-density (HD) SRAMs is presented. By means of a feedback loop comprising a servo-amplifier and a commondrain MOSFET, a current matching the respective bit-line leakage is injected onto the line during precharge and sensing, preventing the respective capacitances from erroneous discharges. The technique is able to handle leakages ...
