What causes the depolarizing effect of an excitatory postsynaptic potential?
 | |
 |
the influx of calcium ions; |
 |
the efflux of calcium ions; |
 |
the influx of potassium ions; |
 |
the efflux of potassium ions; |
 |
the influx of chloride ions; |
INCORRECT - The depolarization of an EPSP is caused by the influx of calcium ions, not the efflux of potassium ions.
