When a slime mold mass or mound is physically separated, the cells find their way back to re-unite. Studies on Physarum have even shown an ability to learn and predict periodic unfavorable conditions in laboratory experiments (Saigusa et al. 2008). Professor John Tyler Bonner, who has spent a lifetime studying slime molds argues that they are "no more than a bag of amoebae encased in a thin slime sheath, yet they manage to have various behaviours that are equal to those of animals who possess muscles and nerves with ganglia – that is, simple brains."
Atsushi Tero of Hokkaido University grew the slime mold Physarum polycephalum in a flat wet dish. Around its initial position representing Tokyo, he placed oat flakes corresponding to the locations of other major cities in the Greater Tokyo Area. As Physarum avoids bright light, light was used to simulate mountains, water and other obstacles. The mold first densely filled the space with plasmodia, then thinned the network to focus on efficiently connected branches. The network strikingly resembled Tokyo's rail system.

Famous quotes containing the word behavior:
“The psychological umbilical cord is more difficult to cut than the real one. We experience our children as extensions of ourselves, and we feel as though their behavior is an expression of something within us...instead of an expression of something in them. We see in our children our own reflection, and when we dont like what we see, we feel angry at the reflection.”
—Elaine Heffner (20th century)
“The fact that behavior is normal, or consistent with childhood development, does not necessarily make it desirable or acceptable...Undesirable impulses do not have to be embraces as something good in order to be accepted as normal. Neither does childrens behavior that is unacceptable have to be condemned as bad, in order to bring it under control.”
—Elaine Heffner (20th century)
“No one thinks anything silly is suitable when they are an adolescent. Such an enormous share of their own behavior is silly that they lose all proper perspective on silliness, like a baker who is nauseated by the sight of his own eclairs. This provides another good argument for the emerging theory that the best use of cryogenics is to freeze all human beings when they are between the ages of twelve and nineteen.”
—Anna Quindlen (20th century)
