Our story begins in California in the late 1990s, where a group of scientists conducted a fascinating experiment with cats. These cats were shown a movie while having electrodes attached to the visual areas of their brains. This setup allowed researchers to record how the cats experienced the world around them by monitoring their brain activity. By analyzing this data, the scientists could reconstruct images from the movies as the cats saw them, including things like tree trunks, branches, and even a man’s face.
Understanding how our brains encode and decode information could lead to incredible advancements, such as telepathy. While this might sound like something out of a science fiction movie, the scientific term for this concept is Brain-to-Brain Communication. However, it’s not about directly connecting two brains. Instead, it involves a computer known as a Brain-Computer Interface. This interface decodes thoughts from one brain and transmits them to another.
In one experiment, participants were able to control the movement of a rat’s tail just by thinking about it. Both a human participant and a rat were connected to a Brain-Computer Interface. When the participant thought about moving the rat’s tail, their thoughts were captured by the computer, converted into electrical signals, and sent to the rat’s motor cortex, causing the tail to move.
Recently, scientists achieved Brain-to-Brain communication between humans for the first time. In this study, a message was encoded by the sender while an EEG recorded their brain’s electrical activity. This message was then transmitted from India to France and delivered to the receiver’s brain using magnetic stimulation and flashes of light. The message was simply “Hello.”
This experiment shows that brain-to-brain communication is possible, although it currently relies on computers and special equipment, making it slow. While it may not be as smooth as in the movies, technology is advancing and bringing us closer to this reality.
Imagine if you could wear a device that allowed you to communicate through thought instead of speaking or texting. Would you be interested in that? And what would you choose to say?

Understanding how our brains encode information—and how we can decode it—could potentially lead to advancements like telepathy. While it may sound like science fiction, the scientific term for this concept is Brain-to-Brain Communication. However, it’s not a direct connection between brains; instead, it involves a computer known as a Brain-Computer Interface. This interface decodes thoughts and transmits them to another brain.
In one study, participants were able to control the movement of a rat’s tail through thought alone. Both a human participant and a rat were connected to a Brain-Computer Interface. When the participant thought about moving the rat’s tail, their intentions were captured by the computer, converted into electrical signals, and sent to the rat’s motor cortex, causing the tail to flicker.
