Shors & Matzel (1997) suggest replacing the question “Is LTP a mechanism of learning?” with “Is LTP a mechanism of arousal and attention?” However, the failure of experiments to verify the LTP-learning hypothesis may arise not because it is untrue, but because in its current guise, it is not properly testable. If so, then the LTP-attention hypothesis is untestable, as well.
