Title: Anticipation of periodic environmental changes in an amoeba
Authors: Saigusa, Tetsu
Nakagaki, Toshiyuki
Abstract: The amoeboid organism of true slime mold, the plasmodium of Physarum polycephalum, had capacity of memorizing a periodic event. The organism showed vigorous locomotion in favarite conditions. When stimulation of the unfavorable conditions was given in a pulse-like regime and was repeated three times at interval of 60 minutes, the amoeba reduced the locomotion speed in response to each pulse. Even though the favorite conditions were kept to be constant after the periodic pulses, the amoeba spontaneously reduced the locomotion speed at the timing of next pulse (after 60 minutes). This means that the amoeba anticipated the next environmental change.
