Brain in a Vat

Posted in Philosophy, Technology at 7:20 pm by Danny Dawson

Tell me: when you take neurons from a rat and put them in a dish, and cultivate them to create a neural network which interacts with the environment it is able to percieve, what have you created? Is it still a rat? Is it just a bunch of cells? Is it…human?

Now what if you take neurons from a human and put them in a dish, and cultivate them to create a neural network which interacts with the environment it is able to percieve: then what have you created? Is it still a human? Is it just a bunch of cells? Is it even any more human than the rat? Do the laws of morality still apply?

In the case below, scientists have given their “neural network” an environment it can interact with in the form of the dimensions such as up, down, left, right, tilt, etc., as well as a body it has the ability to control, in the form of a plane. But tell me, what motivation does the neural network have to maintain its bearings and stability unless it knows fear or joy? Does this neural network have a pleasure center, or a will to exist? If it does, is it any less of a living creature than a car-accident victim on life-support? What is this new being?

This news both excites and scares me. It excites me because studies such as these have the ability to provide a significant amount of information about our own consciousnesses. It scares me because I sincerely expect a strong backlash from religious conservatives about the morality of these studies if they are to continue. They will bring up the same points I have mentioned above.

And I will not be able to refute them.

Discuss.

Currently the brain has learned enough to be able to control the pitch and roll of the simulated F-22 fighter jet in weather conditions ranging from blue skies to hurricane-force winds. Initially the aircraft drifted, because the brain hadn’t figured out how to control its “body,” but over time the neurons learned to stabilize the aircraft to a straight, level flight…

While scientists can study neural activities from groups of cells in a dish, they can’t watch them learn and grow as they would within a living body unless the neurons have some kind of body to interact with.

By taking these cells and giving them back a “body,” the researchers hope to uncover how the neurons communicate with each other and eventually translate that knowledge to develop novel computing architecture.

“Granted, this is just a handful of neurons in a dish,” said Potter, an assistant professor at Georgia Tech’s neuroengineering laboratory. “It isn’t a full-blown brain. It doesn’t have a real body. But with this kind of system you can literally watch these things compute and you have a chance to learn how the brain does its computation.”

Spontaneity

Posted in Philosophy, Travel at 3:51 pm by Danny Dawson

For better or worse, I made a change today. My prior plans included me waiting until the 21st of this month to fly out to California, find myself a job, and then fly back home, collect my things, return to CA and start my life there, couch-hopping with friends until I can find and afford a place of my own. This morning, I got tired of the waiting and anticipation, and I quit. I quit my job. I quit waiting. I quit living each day waiting for another day to come.

Now, I pack. This weekend I go with my mother to my cousin’s wedding in Daytona (congrats Nikki and Ray), and when I return from that excursion there will be a final packing of my bags and boxes. Then, California. I’ll leave most of my stuff with my mom in easy-to-ship boxes ready to meet me at whatever beautiful new apartment or hole-in-the-wall warehouse studio I find.

Am I excited? Yes. Am I nervous? Yes. Am I a fool? Yes.

The sky is bright and blue and I am free to go.

Jesus took a blank check (but needed two forms of valid ID)

I tried to get into position to do a fingertip push-up today, and met with little success. I can get into the upright position, but as soon as I begin to lower my body, my wrist collapses and I fall on my face. When this happened the first time, I just laid there and savored the moment.

I’m convinced that Jesus Christ was a waiter sometime between the ages of 13 and 30. That’s why such a large portion of his life went undocumented. Maybe it was a carpentry-themed restaurant. Latkes were “potato drywall.” It wasn’t a very successful restaurant, mind you.

I, personally, would like to read a chronology of Jesus’ missing years, written as a joke. “Oh, Christ! You’re short-pouring the Manischewitz again!”

Other things I have lined up in my reading queue:
Ashes to Ashes : America’s Hundred-Year Cigarette War, the Public Health, and the Unabashed Triumph of Philip Morris
The Writings of Carlos Castaneda

I found out recently that my old webserver is indeed dead and gone. Its remains were witnessed by a friend of mine, which means those 3 years of my life are gone, not including the little you can find through the Wayback Machine. Ah, well. Many of my physical posessions have also been lost to the world, including my high school diploma, my baby book, and many pictures of people I don’t keep in touch with. Just another reason I’d love to live in the mountains of a foreign country. Also another reason Memento scares the platelets out of me — my memories are very valuable right now. They’re the only thing that can’t be taken from me prove I existed.
