Depolarization - Wikipedia
Depolarization is the process by which the membrane potential becomes less negative, facilitating the generation of an action potential. [6] For this rapid change to take place within the interior of the cell, several events must occur along the plasma membrane of the cell.
去极化 - 维基百科，自由的百科全书
在 生物学 中， 去极化 （depolarization）是 静息电位 减小的过程或状态，即细胞的 膜电位 向负值减少（正值增加）的方向变化。 例如：细胞静息电位为-70mV，其后膜电位变为-50mV，则称该细胞去极化。 若是 医学 中，人为使用药物或器械将心肌去极化，另称 除极[1] 、 除极化。 在 神经元 和其他的细胞中，一个足够大的去极化作用将会导致 动作电位。 過極化 则与之相反，会抑制动作电位的发生。 静息时细胞的膜电位处于一定的负值水平，当细胞受到外界刺激时，静息电位 …

This type of experiment is similar to the physiological action of light, which suppresses glutamate release from photoreceptors and thus depolarizes on-type bipolar cells. 来自 Cambridge …
Depolarization (Definition + Process) - Practical Psychology
2022年7月6日 · Depolarization is a shift in a cell's electric charge that makes the cell's interior increasingly more positive than the exterior. Electrical stimuli, or excitatory stimuli that raise the cell's voltage, cause the voltage-gated ion channels to open in the cell.
Depolarization: Definition, Mechanism, vs. Repolarization
2024年4月30日 · Depolarization is the cellular event characterized by the shift in the distribution of electric charges within a cell, particularly evident in cell membranes, majorly neural membranes for the conduction of impulses.
Depolarization vs. Repolarization of the Heart (2024)
2024年10月18日 · Depolarization is caused by the influx of sodium (Na+) ions into the heart cells, making the inside of the cells more positive and triggering contraction. Repolarization occurs when potassium (K+) ions leave the cells, restoring …
Depolarization - Biology Simple
2024年3月6日 · Depolarization is the process of a neuron’s membrane potential becoming less negative. Depolarization occurs when the neuron receives a stimulus, causing positive ions to enter the cell and shifting the electrical charge towards a more positive state.
Depolarization - definition - @neurochallenged
Depolarization - movement of a cell's membrane potential to a more positive value (i.e. movement closer to zero from resting membrane potential). When a neuron is depolarized, it is more likely to fire an action potential.
