Heads up, folks: the Glass Brain

It appears our brains are about to be hacked, which is not necessarily a bad thing...

"Second Life founder creates Glass Brain, a system that lets you explore your brain in real-time" is a headline from Neurogadget.  According to the article,
[Philip] Rosedale made his wife a cap studded with electroencephalogram (EEG) electrodes that measure differences in electric potential in order to record brain activity, while he wore a virtual reality headset to explore her brain in 3D, as flashes of light displayed her brain activity from the EEG.

For an idea of what he saw, here's a Glass Brain flythrough:

This visualization was done in Unity3D; it allows the user to fly around and through the brain with a game pad while seeing real-time live brain activity from someone wearing an EEG cap. Rosedale collaborated with the Neuroscape Lab in San Francisco to produce the Glass Brain.  However, his main project at present is High Fidelity, which is:
...building a new virtual world enabling rich avatar interactions driven by sensor-equipped hardware, simulated and served by devices (phones, tablets and laptops/desktops) contributed by end-users.
Surf on over to the page to see what he means by "contributed by end-users." You're invited by Rosedale and his team to sign up for alpha and will be notified when it's available.

A related article found at Neurogadget is Brain-Machine-Brain Interface (BMBI).

More on the topic of brain-computer interfacing Wednesday.
