  1. 3. The period during which a neuron cannot fire another action potential.
  2. 4. The movement of neurotransmitters across the synaptic cleft occurs at the:
  3. 5. The rapid electrical signal that travels down an axon
  4. 7. The ion that rushes into the neuron during depolarization.
  5. 9. The addition of multiple postsynaptic potentials.
  6. 10. The electrical charge difference across the membrane at rest.
Down
  1. 1. A postsynaptic potential that makes the neuron more likely to fire.
  2. 2. The minimum membrane voltage required to trigger an action potential.
  3. 6. The ion that exits the neuron during repolarization.
  4. 8. A postsynaptic potential that makes the neuron less likely to fire.
