The slime mold Physarum polycephalum is renowned for its incredible perceived intelligence despite it being a unicellular organism devoid of a central nervous system. Slime molds did the same thing at intervals of 60 and 90 minutes, although, on average, only about half of the slime molds tested showed spontaneous slowing in the absence of an environmental change.
This Weirdly Smart, Creeping Slime Is Redefining Our - ScienceAlert Hikers often spot them clinging to the sides of rotting logs like spilled bowls of extra cheesy macaroni. "That triggered a wave of research into what other kinds of more difficult scenarios we can test the slime mold with," Reid said. Physarum polycephalum, a vegetative stage of acellular slime mould has repeatedly, during the last decade, demonstrated its unexpected computing abilities 8 especially for reproducing road networks. A simple mechanism underpinning the slime mold Physarum polycephalum's behaviors is identified: A stimulus triggers the release of a signaling molecule, which generates a feedback loop and enables the movement of information throughout the organism''s body. For the study, researchers from Belgium and France sought to demonstrate "habituation learning" in a brainless organism.
Maze-solving by an amoeboid organism | Nature These problems can be complex, and yet P. polycephalum can solve them with its extremely limited cognitive architecture. This paper proposes a Physarum-inspired multi-agent system to reveal the evolution of Physarum transportation networks. Esta fase do ciclo de vida . It .
