Big Tech Wants to Harvest Your Thoughts

Scientists at the University of California have developed a technology that can decode brain activity to manipulate visual perceptions. By projecting patterns of high-contrast bars onto a screen, researchers trained mice to associate specific movements with drinking water. They then used a laser system to monitor which neurons were activated in response to these visual stimuli.

Using a second laser system, they were able to selectively activate the same neurons, effectively "planting" images in the mouse's mind. When these implanted images were moved vertically or horizontally, the mice responded as if they had seen the actual images. This technique, which allows scientists to read and write to the brain, has the potential to be applied to humans in the future.

It was demonstrated that this technology can "decode the mind" with remarkable accuracy, enabling scientists to understand and influence brain activity in ways that were previously impossible. The researchers emphasized the ethical implications of this powerful technology, noting the responsibility they bear in developing a tool that could manipulate human thoughts and perceptions.
