despolarizar
- It is hypothesized that when the stereocilia are deflected, the tip-links are stretched and ion channels are opened, thus causing the sensory cell to become depolarized and creating a receptor potential within the cell.
- cell depolarizes
Examples
-
See, somehow it's still firing bioelectrical signals to depolarize cells throughout the entire nervous system, which is weird.
-
To restore normal function, the technician needs to depolarize the electrical circuit in the device.
-
These changes are caused as different chambers of the heart depolarize or reduce their electrical charges to nearly zero at the start of each contraction.

You get a rush of current going by you and that rush of current depolarizes the membrane.
-
While the stereocilia return to their resting position, the cell depolarizes (from approximately -70 mV to -65 mV) and at the same time contracts.
Academic text (1998) -
Stimulation of the hair bundles of the sensory cells induces an influx of positively charged potassium ions, which depolarize the negatively charged cells.
Academic text (1998) -
Ventricular myocytes must depolarize and repolarize—contract and relax—in unison for maximal pumping efficiency.
Fiction book (2001) -

Etymology
Depolarize comes from de- meaning 'remove' and polarize, which comes from pole meaning 'pole' like the North and South. So in electricity or a cell, to depolarize is to take away the opposite charges between poles, which reduces the strong charge difference.
