Smart behavior of true slime mold in a labyrinth

Res Microbiol. 2001 Nov;152(9):767-70. doi: 10.1016/s0923-2508(01)01259-1.


Even for humans it is not easy to solve a maze. But the plasmodium of true slime mold, an amoeba-like unicellular organism, has shown an amazing ability to do so. This implies that an algorithm and a high computing capacity are included in the unicellular organism. In this report, we discuss information processing in the microorganism to focus on the issue as to whether the maze-solving behavior is akin to primitive intelligence.
