Electronic Cat Brain- Coming Right Up

04/22/2010 11:56 AM

University of Michigan researchers are designing a computer that is modelled after a Cat brain, using a synapse like device they call a memristor. The memristor remembers past voltages it has been exposed to, and acts like a synapse rather than a simple binary transistor.

Conventional transistor computers process linear sequentially, while the use of the memristor synapse architecture will permit a more simultaneous parallel processing, like the cat brain.

The researcher has connected two electronic circuits with one memristor and demonstrated that this system is capable of a memory and learning process called "spike timing dependent plasticity." In other words, the connections between neurons are able to become stronger based on when they are stimulated in relation to each other. Spike timing dependent plasticity is thought to be the basis for memory and learning in mammalian brains.

Here's the link: http://www.ns.umich.edu/htdocs/releases/story.php?id=7633

No word on whether a functional memristor device will be able to design and develop historical longbows, (like a certain cat we know) or fixate on mice. But we have a hunch.

Hi, Milo,

I can't wait for Del to get ahold of this one!

Do you think having an electronic brain will change him much?

I wonder why the cat was chosen over other animals? Although all species, including the human, can be easily distracted it seems like the cat is particularly so. I know mine will suddenly go tearing across the lawn and up a tree for what appears to be no reason. I would not like my computer to do that while I was using it.

Perhaps the choice was made for the focus during hunting. Little seems to distract a cat while it's focused on its prey.

Hello, SavvyExacta. From the link:

A cat can recognize a face faster and more efficiently than a supercomputer.

That's one reason a feline brain is the model for a biologically-inspired computer project involving the University of Michigan.

post script: thanks, Milo. This is pretty interesting.

I did skim through the article and see that line. I just wondered why a cat opposed to another animal? I'm sure there are other animals that recognize faces just as quickly. The rest of my post was tongue-in-cheek example. :)

Cats have been studied a lot. They have this interesting dichotomy: on the one hand, they are cognitively uncooperative. No tricks, thanx. On the other hand, their physical responses to stimuli have a remarkable cooperative quality. They are like putty. This is why a cat can survive being thrown out of a second storey window, the "nine lives" reputation due to flexibility, shock absorbance motion responses etc. The part of cat's brain that controls its body is powerfully programmed to "go with the flow".

One of the earliest successes of electrical stimulator prosthetics involved walking an anaesthetized cat around a room. I bet it looked very smooth. Not so transferable in a human, however. And think about dogs: the opposite of the cat. Cognitively cooperative, but physically.... awkward.

So I would guess, another reason for modeling on a cat's brain, is with robotics applications in mind - the goal of fluid, controlled physical movement.

Obviously, you are not using Microsoft software...

Where in 8 days it was missed by all except two sharp eyed guests.

Apparently a different treatment/different section gets different results.

I saw it as a new technology and posted appropriately, adding a bit of a CR4 community twist.

Ftttz sptttzz hissss ftttzzz catzzz brain my ar$e.
They'll never get the coefficient of furryosity right, us catss can even do furrier transfurrrs in our sleep, come to think of it we do most stuff in our sleep.

The flowchart for the electronic cat brain has only four boxes on it.

1) Only eat food human purchased and prepared if it is expensive and smells bad.
2) Dispose of used food. Use cat box if human cleaned it. Use floor if cat box not cleaned
3) Ignore human and refuse to play. Be rude. Never show any personality above "cat-a-tonic"
4) Sleep

You have obviously never learned how to smile at a cat* or how to play with one.
When I was a kitten I would retreive silver paper balls throw for me, climbing up the hesian wallpaper and curtains was a good game too.
I can comunicte my wishes with a wide variety of noises and wubbing techniques.
Even old Grandpa hooman who I don't see very often asked 'what is this cat trying to make me do?' I was wubbing his leg and then walking towards the front door, then going back and repeating the manouver.
Some one said 'don't be thick...she wants to be let out the front door'.
Del

* Look at the cat, make a small smile with your mouth (not a damn great cat eating grin) squeeze your eyes shut for a count of about 2 and the open them.
Repeat as necessary with scratches behind ears (the cat's not yours)
You will observe the cat ding the same smile thing back at you...unless of course it doesn't like you, in which case you'll just have to pull it off your face

You sure you are not a dog? Retrieve is an awful strong word for a Cat don't you think, maybe in the case of a cat chase is more appropriate. Retrieve implies you brought the balls back to who ever threw them.

Indeed, I brought back the shiny silver paper balls so they could be flicked again...until I was fed up with the game of course.
Sometimes I'd catch 'em in the air or whack 'em with my paw

I've been around cats all my life. It took me about 20 years before I learned to really "connect" to a cat. At first I just saw a furry eating machine. But later I learned from my wife about connecting with cats. There's really a lot of depth in a cat. Once you make the "connection," a special bond is created and you have a buddy for life. It's also fun to observe all the many emotions and expressions of these smart critters. I can look into the eyes of a cat and a cat can look into my eyes and we both know what we are thinking. Can researchers really model a cat ... absolutely not.
