Fig. 4. RPeD1 soma-ablated snails can still access long-term memory (LTM). A cohort (N=10) of snails received two 45-min training sessions, with a 1 h interval between the sessions. One hour following Session 2, all snails had their RPeD1 soma ablated (RPeD1 SOAB). When we tested for memory 3 days later (MT), it was present. That is, the criteria for memory were met. However, to be certain that the apparent memory was truly memory and not unresponsiveness of the snails, they were challenged 1 h later with a 45-min change-of-context test (CC). These snails are still capable of responding, and thus RPeD1 soma-ablated snails can still access previously encoded LTM.
