You are studying behavior in Aplysia, and discover a isolated population of these animals that show impaired habituation to the syphon/gill reflex behavior, that is they show a withdrawal reflex as strong on the 20th trial as the 1st trial.

a) What channels or receptors might be altered in this population? Explain.

b) Would you predict that these animals would also fail to show a sensitization response based on your answer to a? Why or why not?
