Brain compass implant gives blind rats ‘internal GPS ‘

I’m dreaming that humans can expand their senses through artificial sensors for geomagnetism, ultraviolet, radio waves, ultrasonic waves and so on,” says Yuji Ikegaya of the University of Tokyo in Japan, head of the team that installed and tested the 2.5-gram implant. “Ultrasonic and radio-wave sensors may enable the next generation of human-to-human communicationMovie Camera,” he says.
Psychic GPS
The neuroprosthesis consists of a geomagnetic compass – a version of the microchip found in smartphones – and two electrodes that fit into the animals’ visual cortices, the areas of the brain that process visual information.
Whenever the rat positioned its head within 20 degrees either side of north, the electrodes sent pulses of electricity into its right visual cortex. When the rat aligned its head in a southerly direction, the left visual cortex was stimulated. The stimulation allowed blind rats to build up a mental map of their surroundings without any visual cues.

Yes, please.
