Just thought I would share this.

quote:
"It's essentially a dish with 60 electrodes arranged in a dish at the bottom," explained DeMarse, who designed the study.

"Over that we put the living cortical neurons from rats, which rapidly begin to reconnect themselves, forming a living neural network -- a brain."

I once heard about simulated brains (neural networks) flying planes, but this is so much better.

(wonder how good those 60 cells fly)

There are much more than 60 neurons, but they only have 60 electrode contact points.

It'll be cool to see if this type of "living computer" could be used more extensively.

It sounds amazing. Honestly I'd like to see a flight made in the F22 simulator done by that neural network.

I want to know what the "soul believers" think of this.

I am a "soul believer" and I find it interesting, which is why I shared it.

I wonder how they trained it. I know they can make remote controlled rats by implanting electrodes in them that stimulate their whiskers in the direction they want the rat to go, and then reward the rat by stimulating pleasure sensors when the rat goes the correct direction. I suppose its a similar setup (ala, stimulating pleasure sensors) but really, how do you know where they are in a dish as apposed to in something that has been disected and studied for centuries (like a rat brain).

Come on, it's just using the electrochemical and adaptive properties of living cells to propogate electric signals in a specific manner. What's more, it's from a rat.

It has no more of a soul that the PC I'm writing this on.

But the basic question is, how did the rats learn to fly in the first place?

Intriguing!

Just as a small processor dedicated to a specific task can be more efficient than a large processor sharing several tasks, A specifically designed bio-processor could be a thousand times more capable than a human one in certain applications. What's more, as the processing power of a biological brain increases exponentially with the addition of each cortical neuron, even a few hundred cells could provide far more computing power than conventional electronic processors.

However, I imagine that the whole input/output cycle may lag significantly in comparison when applied to small processing tasks.

How the Rats learned to fly.
"The short version"

First i catch 'm with an special device mostly called a trap or an net.
Then i go stand on suho's new tower in the east wing
Then puff some grass smoke into it's cage and open the door, when the rat doesn't fly i repeat the smoke action a couple of times. IF the rat still doesn't fly i put it on special stick and wing the oldtime baseball bat.
I learned that in these situations ALL rats are able to fly, though landing is still tough for most of 'm.
