Somatic Inheritance of Habituation of Responses to Light in Planarians.
Planarians show long-lasting reversible decrease of responses to a photic stimulus repeated 25 times each day. This habituation was found to be significantly faster in regenerated offspring of previously habituated planarians, and was also transferred by cannibalization, thus resembling light-shock conditioning. Habituation provides a new situation in which to study the somatic inheritance of learning in planarians.
