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.

This active ingredient acts by interfering with the impulse transmission in the nervous system and results in the eventual death of the pests.

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.
Voskuhl showed that testosterone, whether administered before or after disease induction, restored proper nerve impulse transmission in mice with EAE (The Journal of Neuroscience 2012;32:12312).
Following nerve impulse transmission, acetylcholine is released from the postsynaptic membrane receptor and is broken down by acetylcholinesterase (AChE) to choline and acetic acid.
Calcium also prevents muscle cramps, and facilitates nerve impulse transmission, muscle growth, and muscle contractions.
(18) Therefore, due to a lack of ACh, normal impulse transmission is disabled because receptors at the myonerual junction cannot depolarize.
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.In 2001, Nasa researchers studied cancer incidence in relation to sunlight exposure and concluded that more than 23,000 deaths in the Northern US could be attributed to lack of sunlight.
Thyroid hormone is essential for neuron formation, synapse development, formation of myelin (the sheath surrounding neurons that enhances nerve impulse transmission), and migration of neurons to their proper places in the brain.
