Abstract

To study how organism responds to periodic stimulation is meaningful since it may be an approach to an elementary capacity of time memory and learning in chronological events. We reported here that the ability of time memory found in true slime mold Physarum was also found in a protozoan ciliate, Blepharisma japonicum and a green plant Chara. Stimulation of temperature or light was repeated several times in a regular period, and the creature anticipated the next timing of stimulation. After the anticipatory behavior disappeared some time later, another single stimulation triggered recalling of periodicity of the previous stimulation. We discuss that the observed capacity is expected to be common in a range of species as the similar capacity has been reported in true slime mold Physarum. The observed responses were, however, dependent of individual of organism and a wide range of different responses was observed. We need an extensive study of both experimental characterization and mathematical modeling of ethological dynamics. abstract environment.
