Question

LTP in the hippocampus has many parallels to long-term plasticity in Aplysia. Which of the following is not one of those parallels?

A. Both have an early, transient phase that depends on posttranslational changes in membrane proteins
B. Both have later, long-lasting changes that require CREB activation
C. Both lead to structural changes in the active neurons
D. Both are likely involved in long-term information storage
E. All of the above are parallels between the two systems

Answer 1

All of the options presented (A through D) are parallels between LTP in the hippocampus and long-term plasticity in Aplysia, thus making option E correct that all of the above are parallels.

Step-by-step explanation:

The student asked which of the following is not a parallel between long-term plasticity in the hippocampus (LTP) and long-term plasticity in Aplysia:

Both have an early, transient phase that depends on posttranslational changes in membrane proteins.

Both have later, long-lasting changes that require CREB activation.

Both lead to structural changes in the active neurons.

Both are likely involved in long-term information storage. All of the above are parallels between the two systems.

In this context, each of the options listed (A through D) correctly describes parallels between LTP in the hippocampus and long-term plasticity in Aplysia. Therefore, option E is correct as all of the mentioned options are indeed parallels between the two systems.
