Earthworm individualities when facing a conflict between turn alternation and aversive learning

We investigated whether an aversive stimulus affects turn alternation (TA) in earthworms. TA is a tendency to turn in the direction opposite the preceding turn. The apparatuses used in TA studies are similar to those used in conditioning studies. However, there are no studies in invertebrates that combine these two types of studies. Each earthworm was tested in a sufficient number of trials, to allow us to evaluate its unique response.
Two of ten earthworms stopped making TAs after aversive stimulation, while one worm increased the TA rate after stimulation. Earthworm individualities become obvious at the conflict between alternation behaviors.
