When we make our small change, the membrane depolarizes. This means the electric field becomes weaker, and the repulsion from the inside of the cell felt by the chloride ions is weakened. thalassemia articlesWebWhen the equilibrium potential of Cl − ions is close to the membrane resting potential, the opening of Cl − channels does not reveal a hyperpolarizing current at the resting potential (from which comes the term ‘silent’ for this inhibition). However, when the membrane is depolarized by an EPSP, the inhibition is no longer silent, but ... synonyms of offshoot

"WebNernst potential for chloride is the same as that resting potential. In neurons that have a Cl– pump, chloride is pumped outwards, so [Cl –] o/[Cl ]i increases, so ECl decreases below VR. 1 • While muscle cells have a resting potential of about –90 mV, most neurons have a resting potential of about –65 mV (range – 60 to –70 mV).
