Researchers have discovered that a yellow slime mold known as Physarum Polycephalum is able to retain memories, even though it doesn\u2019t have a brain. —\u00a0Click to Tweet<\/a>.<\/p>\n

\"Every<\/a>
Every slime mold species is different, but the more we learn about these organisms the more interesting traits we observe.<\/figcaption><\/figure>\n

But researchers stress that the puddles of goo<\/a> don\u2019t possess a memory like we do; instead, the slime mold leaves behind a translucent slime trail that helps it to \u201cremember.\u201d<\/p>\n

This discovery could very well change the way scientists define memory. Even though the slime mold doesn\u2019t possess a brain, it can use its slime trail to solve complex mazes and make irrational decisions.<\/p>\n

Remember, Remember<\/strong><\/p>\n

At one time, slime molds were thought of as a fungus, until it was discovered that they are actually composed of a number of microbes known as protists.<\/p>\n

Slime molds come in all shapes and sizes, and vary in \u201cintelligence.\u201d The yellow slime known as Physarum Polycephalum is a single cell that is over a one square foot in size, and is composed of several million identical cell nuclei.<\/p>\n

Researchers observed the yellow slime and noticed that the Physarum Polycephalum would use its slime trail to retrace its steps, but would become confused when researchers covered its slime trail with extra slime. So the researchers decided to test the yellow slime’s memory by having it attempt to traverse a maze to reach a sugary meal.<\/p>\n

\"How<\/a>
How would this path-finding trait have been adaptive in the wild, and how could their “learning” bio-mechanisms have led to more complex learning systems? These questions are still unanswered by scientists.<\/figcaption><\/figure>\n

Researchers noted that the slime mold was able to find the meal three times more often and thirty times faster when it followed its slime trail. But it took the slime molds almost ten times longer when the researchers put down extra slime to \u201cblind\u201d the yellow slime of its trail.<\/p>\n

Helping Us Understand The Past<\/strong><\/p>\n

These\u00a0findings<\/a> are particularly important because it is the first time a creature without a brain has been observed using spatial memory. Researchers believe that this spatial memory could have been used to ancient organisms to solve problems, and could help us to better understand how our ancient ancestors survived.<\/p>\n","protected":false},"excerpt":{"rendered":"
