Graded Potentials
If concentration of ions across plasma membrane changes, membrane's voltage changes
Hyperpolarisation
- Increase in polarity to make it more negative
- Cause
- Efflux of K+ through passive K+ channels
- Influx of Cl- through passive Cl- channels
Depolarisation
- Decrease in polarity to make it more positive
- Cause
- Influx of Na+ through (normally closed) Na+ channels
