Positive feedback occurs when a deviation from the optimum point causes a further deviation, creating aSelf-amplifying cycle, like an influx of sodium ions causing more influx.
- influx of sodium ions causes further influx of sodium ions - deviation from optimum point causes further deviation - increase in x causes more of y - more of y causes further increase in x

| Back | - influx of sodium ions causes further influx of sodium ions - deviation from optimum point causes further deviation - increase in x causes more of y - more of y causes further increase in x |
