C) Input neurons A and B fire a burst of action potentials at the same time that output neurons I and II fire a burst of action potentials.
D) Input neurons A and B fire a burst of action potentials at the same time that output neurons I and II are depolarized.
E) Input neuron C fires a burst of action potentials at the same time that output neuron II is active.

As defined in Section 10.5 of the textbook, cooperativity induces LTP at a synapse when two events coincide: (1) The presynaptic cell fires and releases neurotransmitters and (2) the postsynaptic cell is in a depolarized state. Neurons Aand Csynapse onto neurons I and II. If activity in neurons Aand Ccoincides with either a depolarization or an action potential (which is a depolarization) in the postsynaptic cell, then LTP will be induced. For (e), neuron Cdoes not synapse onto neuron II.
