With news that Elon Musk was attempting to build a "neural lace," the concept of a brain-machine interface (BMI) entered the public lexicon. Now, researchers at Wits University in Johannesburg, South Africa, claim to have linked a human mind to the Internet in real time — a biomedical first.
The project, dubbed the "Brainternet," required the researchers to gather EEG brainwave signals using only an Emotiv EEG device and a simple Raspberry Pi computer. The experiment allowed the human brain to become an information node in the Internet of Things (IoT).
The experiment's supervisor, Adam Pantanowitz, described it this way:
Brainternet is a new frontier in brain-computer interface systems. There is a lack of easily understood data about how a human brain works and processes information. Brainternet seeks to simplify a person's understanding of their own brain and the brains of others. It does this through continuous monitoring of brain activity as well as enabling some interactivity.
