Question

Suppose you have new inhibitors of signalling enzymes in the sea slug, Aplysia californica. You possess a protein phosphatase inhibitor that specifically inhibits the enzyme that dephosphorylates CREB. You also have a specific adenylyl cyclase inhibitor that blocks production of cyclic AMP. Suppose you fed a group of sea slugs phosphatase inhibitor pellets a minutes before each "training session" where you induce the sensitization of the gill withdrawal reflex. A second group of slugs gets fed the adenylyl cyclase inhibitor pellets. Finally, a third group of slugs are fed Fruity Pebbles (a breakfast cereal resembles the pellets) as a control. Which group of slugs would form a long-term memory the fastest, i.e, become sensitized after the fewest repetitions of the routine? Which would be slowest to learn? Please explain

Explanation / Answer

The third group will be fastest in learning as it is not introduced to any of the inhibitors. The first and second group be slowest in learning because it is introduced with the inhibitors of CREB and cyclic AMP. These are associated with the long term memory of the brain hence the inhibition will affect the memory. cyclic amp are directly associated with the learning hence second group will be most slow in learning.
