Which is true for spike-timing-dependent plasticity? Select all that apply.

A) If a postsynaptic neuron repeatedly fires action potentials before a presynaptic neuron, the synapse is potentiated.
B) If a presynaptic neuron repeatedly fires action potentials before a postsynaptic neuron, the synapse is depressed.
C) If a presynaptic neuron repeatedly fires action potentials before a postsynaptic neuron, the synapse is potentiated.
D) If a presynaptic neuron fires action potentials more than 100 ms prior to the postsynaptic neuron, the synapse is depressed.
E) If a postsynaptic neuron fires action potentials more than 100 ms after the presynaptic neuron, the synapse is depressed.
