Which Statement(s) Support(s) the Hypothesis That Actin Polymerization Is Critical

Which statement(s) support(s) the hypothesis that actin polymerization is critical to stabilizing LTP? (Select all that apply.)

A) Low-frequency stimulation following LTP induction prevents LTP from enduring.
B) Inhibiting NMDA receptors prevents LTP from enduring.
C) Inhibiting actin polymerization about 15 minutes following LTP induction prevents LTP from enduring.
D) Inhibiting actin polymerization prior to LTP induction does not prevent the generation of LTP.
E) None of the above
