In an experiment, you find that cortical neurons that have not been exposed to glutamate for several days give far stronger responses than those that have been continuously exposed. This is an example of which phenomenon?

This is an example of synaptic scaling, a homeostatic plasticity mechanism where neurons adjust their synaptic strength in response to prolonged changes in activity. In this case, neurons not exposed to glutamate (a major excitatory neurotransmitter) for several days upregulate their responsiveness to compensate for the reduced activity, resulting in stronger responses when they are eventually exposed to glutamate again.
