Temporal summation occurs when rapid, successive impulses from a single presynaptic neuron release enough neurotransmitter to trigger an action potential.
Temporal summation happens when rapid, successive arrivals of nerve impulses from the same presynaptic neuron release enough neurotransmitter to reach the threshold for an action potential.
| Front | Temporal summation |
|---|---|
| Back | two or more nerve impulses arrive in quick succesion from same presynaptic neurone. This makes an action potential more likely because more neurotransmitter is released into synpatic cleft |
