The concept of mind control sounds like something that only exists in sci-fi movies. Until now. Recent work from Zhejiang University on developing a system appears to allow human mind control over the rat’s movements. This “brain-to-brain interface”, or BBI, is achieved by wirelessly coupling the brains of a human operator and a “rat cyborg” and transmitting brain activity in real time.

Brain cells communicate with each other mainly through electrical signals. In this study, the human operators are equipped with electrodes attached to their scalp. Electrical signals are recorded by a computer and translated into specific instructions such as turning left or right, or moving forwards or backwards. The “rat cyborgs” are rats with electrodes implanted into the brain regions that control their movements. When the human operator thinks a specific instruction, the corresponding implanted electrode sends a stimulation signal to the rat’s brain, making it respond to the commanded direction. In one test experiment, rats were asked to complete a series of navigation tasks such as climbing and descending steps, turning left or right, and going through a tunnel in a three-dimensional maze under control of the BBI system. A total of six rats were put into 10 consecutive tests each and all of them were able to complete the pre-determined maze route in 5 minutes with >80% success rate.

According to the authors, future experiments will be focused on communication between two human brains. This could be incorporated into physical therapies, such as helping paralyzed patients re-develop motor skills. As promising as it sounds, however, it’s important to note that electrodes attached to the operator’s scalp cannot record very fine signals, which potentially limits the accuracy and specificity of this BBI system. For example, you could tell my brain to jump, but not how high.

  1. Hello! This is my first visit to your blog! We are a collection of volunteers and starting a new project in a community in the same niche. Your blog provided us valuable information to work on. You have done a outstanding job!

  2. If we can interpret this mind data through electric or any other medium , we can control our all world to not take any bad decision . Like there will be no war between borde army .

  3. Do you think we’ll be able to interpret this data and be able to translate it? If so does that mean we can turn these same signals and process them through a computer meaning we could have a sort of mind control VR type thing. for example something similar to a full dive VR.
