impulse transmission

impulse transmission

[′im‚pəls tranz′mish·ən]
(communications)
Form of signaling which employs impulses of either or both polarities for transmission to indicate the occurrence of transitions in the signals; used principally to reduce the effects of low-frequency interference; the impulses are generally formed by suppressing the low-frequency components, including direct current, of the signals.

Among the topics are polyacrylamide hydrogels obtained by frontal polymerization and their properties, fulvic and humin acids in surface waters of Georgia, modeling the physical mechanism of activation (opening) of ion channels in nerve impulse transmission, and the thermal curing of composite-based epoxy.
Importantly, quantitative tests of specific sensory function, as well as electrophysiological measures of impulse transmission across the site of injury, show an association with the clinical examination, providing further objective confirmation of the sensory gains.
The grant will support neuroscience in 13 core areas, including stem cells, proteomics, crystallography and nuclear magnetic imaging work, structural biology, functional genomics, genetic analysis, neurobehavior in mice, diseases of nerve cells, electrophysiology studies of nerve impulse transmission, drug screening, and biostatistics and computational modeling.
In a key event during nerve impulse transmission glutamate is released from vesicles in the presynaptic neuron, and travels across the synapse to glutamate receptors on the postsynaptic neuron (AMPA, NMDA and KA), resulting in depolarization of the postsynaptic neuron and generation of a postsynaptic action potential.
It's also needed for healthy nerves because it regulates the level of calcium in the blood which is vital for nerve impulse transmission.
Recovery of impulse transmission occurs gradually as new nerve terminals grow and contact is made with the post-synaptic motor endplate.
The changes in sensory function were confirmed objectively by measures of electrical impulse transmission across the site of injury, each of which correlated with the clinical examination.

Lucas Meyer, which developed LECI-PS(TM), says that it naturally replenishes the body's stores of PS which support chemical and impulse transmission between cells by governing the activities of cell membrane proteins.
Importantly, tests of perception of different sensory stimuli as well as measures of electrical impulse transmission across the site of injury correlate with the clinical examination, providing independent and objective confirmation of the changes in sensory function.
