In a wierd new experiment, scientists at Harvard hooked a monkey’s mind as much as a neural internet and tried to stimulate particular person neurons answerable for recognizing faces. By displaying the monkey photos generated by the AI, the scientists tried to activate these explicit neurons as a lot as attainable.
Finally, the AI system discovered to generate photos that might set off particular person mind cells with out additionally activating any of their neighbors, in response to The Atlantic. These photos typically took the type of surreal nightmare footage that vaguely resembled faces or different acquainted shapes — a provocative instance of how sensors and AI are beginning to peer into the organic mind.
The algorithm, referred to as XDREAM, morphed new photos in response to stay suggestions within the type of how strongly a given neuron responded to the picture, in response to analysis shared on-line earlier this yr.

“If cells are dreaming, [these images] are what the cells are dreaming about,” neuroscientist Carlos Ponce informed The Atlantic. “It exposes the visible vocabulary of the mind, in a means that’s unbiased by our anthropomorphic perspective.”
Some neurons responded to photographs that vaguely resembled objects that the scientists acknowledged, suggesting that the researchers recognized the precise neurons that corresponded with explicit real-world objects. A blur that resembled a monkey’s face accompanied by a crimson blotch might have corresponded to a different monkey within the lab that wore a crimson collar. One other blur that resembled a human sporting a surgical masks might have represented the girl who took care of and fed the lab’s monkeys, who wore the same masks.
Different photos that the monkey neurons responded to essentially the most have been much less practical, as a substitute taking the type of numerous streaks and splotches of shade, in response to The Atlantic.
“It was thrilling to lastly let a cell inform us what it’s encoding as a substitute of getting to guess,” stated Ponce.
