Here we quantify the properties of voltage-dependent sodium currents and voltage- and calcium-dependent potassium currents in two important classes of excitatory neurons in the main input layer of the piriform cortex. We identify several classes of these currents and show that their properties are ...
Ileitis modulates potassium and 619 sodium currents in guinea pig dorsal root ganglia sensory neurons. J 620 Physiol 552: 797-807, 2003.Stewart T, Beyak MJ, Vanner S. Ileitis modulates potassium and sodium currents in guinea pig dorsal root ganglia sensory neurons. J Physiol 552: 797-807, ...
a. a very reactive soft silvery-white element of the alkali metal group occurring principally in common salt, Chile saltpetre, and cryolite. Sodium and potassium ions maintain the essential electrolytic balance in living cells. It is used in the production of chemicals, in metallurgy, and, alloye...
If equal amounts of Na+ and K+ were transported across the membrane by the pump, the net charge transfer would be zero; there would be no net flow of current and no effect on the membrane potential. In fact, in many neurons three sodium ions are transported for every potassium ion; so...
Leak channels are found on the cell membrane in neurons and are specific for each ion. This allows for the exchange of sodium and potassium ions without any energy. The leak channels are open when the cell is at rest, which allows sodium and p...
Sodium-potassium pump - also known as the Na+/K+ pump or Na+/K+-ATPase, this is a protein pump found in the cell membrane of neurons (and other animal cells). It acts to transport sodium and potassium ions across the cell membrane in a ratio of 3 sodium
We conclude that the rate of spontaneous action potential firing of Purkinje neurons is controlled by the interaction of Kv3.3 potassium currents and resurgent currents. 展开 关键词: cerebellum, potassium channels, sodium channel, spike trains, knock-out mice, Purkinje neurons ...
Opioid receptors were found to activate two different types of membrane potassium conductance in acutely dissociated neurons from the CA1/subiculum regions... TL Wimpey,C Chavkin - 《Neuron》 被引量: 276发表: 1991年 Effect of imipramine on calcium and potassium currents in isolated bovine ventricu...
Due to the unequal transport of sodium and potassium ions by the Na-K pump, a membrane potential is generated. True or FalseAction Potential:In a nerve cell, an electrochemical gradient shifting causes the firing of a signal from a neuron. These...
Rats fed a high-sodium diet develop elevated sodium levels in their cerebrospinal fluid, which activates ENaCs. Activated ENaCs and/or increased intracellular sodium in neurons activate the RAAS; this releases EDLF in the brain, activating the sympathetic nervous system. The RAAS promotes oxidative...
