Multiple Choice

Refer to figure 14.12. In the text Imagine if the three entorhinal neurons that fire action potentials that trigger action potentials in the CA3 neurons numbered 1 and 3 instead of 2, 4, and 5 as depicted in the figure. When a subsequent action potential is only triggered in CA neuron 1, what would be the resulting activation of additional CA3 neurons?

• A) neuron 1 will activate neuron 3 through previously strengthened synapses
• B) neuron 1 will activate neuron 2 through previously strengthened synapses
• C) neuron 1 will activate neurons 2 through 5 via previously strengthed synapses
• D) only neuron 1 will activate
• E) none of the above
