Depolarization

This is the effect to which the term 'depolarization' has been applied; the experiment really proving that with both light and heat we have the same resolution by the plate of mica, and recompounding by the analyzer, of the ethereal vibrations. ❋ John Tyndall (1856)

The doubts thus thrown upon the question were removed by the experiments of Forbes, who first established the polarization and 'depolarization' of heat. ❋ John Tyndall (1856)

Locally it blocks the initiation and propagation of nerve impulses along an axon by interference with sodium permeability during depolarization. 3,11 Centrally it blocks the presynaptic reuptake of norepinephrine and dopamine. ❋ Unknown (2010)

There are proposed explanations for the end-of-life brain activity as non-functional, generalized neuronal depolarization. ❋ Unknown (2010)

Only then will a greater level of understanding and, ultimately, improved relationships and depolarization, be possible. ❋ Tom Daschle (2010)

Perhaps religion will one day do that, causing the depolarization of the parties along economic and foreign-policy lines, or the rise of a viable third party in some states. ❋ Unknown (2008)

Among the prime cellular targets of mercury are mitochondria, and thimerosal-induced cell death has been associated with the depolarization of mitochondrial membrane, according to the International Journal of Molecular Medicine among several others. ❋ Unknown (2009)

The wave of depolarization/action potential is propogated from one end (dendritic end) to the terminal end of the axon. ❋ Unknown (2008)

Protein channels of the dendrite membrane open allowing the movement of charged chemicals (Na+ ions) across the membrane, which reverses the electrical charge (depolarization). ❋ Unknown (2008)

Perhaps more surprising, the authors found "dramatic depolarization in intergroup differences." ❋ Unknown (2005)

Monti-Bloch and Grosser 29 found the adult human VNO responds to picogram amounts of human skin pheromones with depolarization. ❋ Zoe Brain (2007)

Both the colonial algae Volvox and the unicellular algae Chlamydia have simple “eye spots”, and the depolarization of these spots is sufficient to allow them sense light and act accordingly. ❋ Unknown (2006)

For a nerve cell, depolarization, no matter how achieved is enough to make it fire, and enough to restore visual responses in mice and create photoresponses in worms. ❋ Unknown (2006)

As long as the blogosphere increases social capital I am hopeful that it will eventually result in depolarization. ❋ Unknown (2005)

That requires depolarization of the cell membrane and the restoring of the ionic concentrations of potassium and sodium in less than a thousandth of a second. ❋ GERALD L. SCHROEDER (2001)
