foc.us for research

Open standards, API and requests accepted

Foc.us v2 has all of the features found in your commercial research kit. You can run larger studies with more participants at lower cost. This includes double blind sham mode. Logging of all sessions at 50ms intervals. Set maximum current, maximum voltage, ramp up time and everyhing else.

If you have a custom request – triangle waves, custom patterns – we will code it if we can.

What does this part of the brain do, again?” I asked, pointing to the electrode on my right temple.

“That’s the right inferior frontal cortex,” said Vince Clark, the director of the University of New Mexico Psychology Clinical Neuroscience Center, in Albuquerque. “It does a lot of things. It evaluates rules. People get thrown in jail when it’s impaired. It might help solve math problems. You can’t really isolate what it does. It has emotional components.”

It was early December, and night was falling, though it was barely five. The shadows were getting longer in the lab. My legs felt unusually calm. Something somewhere was buzzing. Outside the window, a tree stood black against the deepening sky.
