Scientists Use Quake 2 To Study the Brains of Mice
An anonymous reader writes "In this week's issue of Nature, scientists from Princeton University trained mice to navigate around a virtual environment using a setup that resembles a combination of a giant trackball and a mini-iMax theater displaying a virtual world rendered using a modified version of the Quake 2 open source game engine. (Here's the academic paper, subscription required.) They hold the mouse's head still atop a giant trackball, which the mouse turns by running. The scientists use the rotations to move the mouse around in the virtual environment, and when he reaches certain places, he gets a reward. Because they are able to hold the head still, they can stick microscopic glass electrodes into individual neurons in the hippocampus of this mouse as it 'navigates.' They find the neural activity that resembles activity during real life navigation, and learned new things about the inputs and computations that are going on inside these neurons, which weren't known before. No word as of yet whether the scientists plan on giving the mice control of the gun. Wonder whether John Carmack ever envisioned this when he opened up the Quake code?"
Yo dawg, I heard you liked mice, so I put a mouse on your mouse.
God spoke to me.
If only we could do this with gamers who need exercise. They get a better immersive experience AND get fit at the same time.
OK, so the open-brain surgery thing is going to be controversial, but...

If I ever get fragged by a mouse, I hope no one ever tells me.
Fragged by a rodent! Damned thing was camping, too, the bastard.
Free Martian Whores!
Great. Now I have to worry about getting pwned by Frankie and Benjy.
Catching mice that get in my house is enough of a pain, but now I have to snag the bastards while they're rocket jumping? Thanks, jerks.
Beats a console controller any day, even lab scientists agree
They initially tried this study using managers, but there was no evidence that the managers were learning anthing or that they even perceived their environment

The researchers originally wanted to use Half-Life instead of Quake 2, but they could never get the mice to do anything in the game other than murdering the scientists.
"FDA staff reviewers expressed concern about the number of patients who were left out of the study because they died."
Just thought I'd point out that
despite all my rage, I am still just a rat in a cage.

Naw, they'll be too busy raiding the cheese shop in Stormwind.
Best "String" Ever!
I wondered why the last arena I logged in to had the quad damage replaced by a wheel of cheese, and why the rocket pickups were shaped like little smudges of peanut butter.
There are some people that if they don't know, you can't tell 'em.
Pinky! Are you thinking what I'm thinking?

Mice already know how to interface with computers, having built the greatest computer in all space and time. The mice are running this quake experiment just so that they have a bit of fun "decommissioning" the hardware later.
-- open source? sounds like the real book --
I'll take a computer than runs Quake 2 at a reasonable 60 fps over a computer that takes millions of years to say "42".
If it was virtual cheese they were after, they'd need look no farther than these jokes, I think.
Umm, I think so Brain. But why do we need polka dotted pants at a lan party? Narf!
Seriously, what did they really learn from this?
They learned about brain structure and relationships between cognition and motor control.
You may not think that's worth it, but we've done a lot worse to mice than non-lethal brain surgery in order to learn a lot less.
I wouldn't let anyone involved in this kind of experiment date my sister.

I know this map.
