For the first time in history, researchers have connected the human brain to the internet. The invention links a small Raspberry Pi computer to a headset with 14 nodes that correspond to different parts of the brain. Each brain wave can be monitored on a screen. In the future, this technology could be used to transfer information back and forth between mind and computer.

"Brainternet" came about as the fourth year project of biomedical students Jemma-Faye Chait and Danielle Winter from the Wits School of Electrical and Information Engineering in Johannesburg, South Africa. The students were supervised by Wits professor Adam Pantanowitz.

According to Pantanowitz, the technology is much less scary than it sounds. "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".
