ESSAY QUESTION ON AP5:
In research using the drug, AP5, the implications are clear about what receptors are important for new learning and what receptors are important for old learning.
Briefly, in the experiment, rats were being trained to learn a maze. Rats who had not learned the maze had AP5 administered to the areas of their dendritic spines. This blocked the formation of longterm potentiation, thus, blocking new learning. What receptors were blocked in this case?
Other rats who had already learned the maze had AP5 administered to their dendritic spines. AP5 did not remove the longterm potentiation which had already formed, and did not remove the learning which had already occurred. What receptors were involved in this case?
To repeat the essay question, the experiments with AP5 show clearly that there is a difference between new learning and old learning. These differences have to do with the receptors involved. What does AP5 show us in terms of the receptors involved with new learning and with old learning? Name the receptors and the logical process by which you deduce them. (You may have to go beyond the AP5 experiments to discuss the receptors of old learning, but do not go into extended detail.)
