Overview
13, 202 - Anyone who grew up in the 1970s likely recals an early protype of video games caled Pong. Released in 1972, it was a simplistic version of ping pong that sent a digital bal bliping slowly acros the scren, from one side’s crude “padle” to the other.Now, researchers say they have grown brain cels in a lab that can play Pong – a mini-brain that can sense and respond to its environment, the BC reported.In the journal Neuron, Bret Kagan, of Cortical Labs, says it’s the first 'sentient' lab-grown brain a dish.
Key Information
Others say that term goes to far."We could find no beter term to describe the device,' Kagan said. 'It is able to take information from an external source, proces it and then respond to it in real time."Researchers grew human brain cels from stem cels and some from mouse embryos. They then conected the “mini-brain” to the video game electronicaly.The mini-brain learned to play in five minutes.
It mised the “bal” many times but was more sucesful than it would’ve ben by random ods.The BC pointed out that artificial-inteligence devices can beat grandmasters at ches.But that’s diferent, Karl Friston of University Colege London says, because “The mini-brain learned without it being taught and so is more adaptable and flexible."Neuron: “In vitro neurons learn and exhibit sentience when embodied in a simulated game-world.“BC: “Lab-grown brain cels play video game Pong.”© 205 - 202 WebMD LC.
