To See, Brain Assembles Sketchy Images Eyes Feed It

"The eye as a camera has been a powerful metaphor for poets and scientists alike, implying that the eye provides the brain with detailed snapshots that form the basis for our rich experience of the world.

Recent studies at the University of California, Berkeley, however, show that the metaphor is more poetic than real. What the eye sends to the brain are mere outlines of the visual world, sketchy impressions that make our vivid visual experience all the more amazing.

"Even though we think we see the world so fully, what we are receiving is really just hints, edges in space and time," said Frank S. Werblin, professor of molecular and cell biology in the College of Letters & Science at UC Berkeley. Werblin is part of UC Berkeley's Health Sciences Initiative, a collaboration among researchers throughout the campus to tackle some of today's major health problems.

The brain interprets this sparse information, probably merging it with images from memory, to create the world we know, he said.

In a paper in today's issue of Nature, doctoral student Botond Roska, M.D., and Werblin provide evidence for between 10 and 12 output channels from the eye to the brain, each carrying a different stripped-down representation of the visual world.

"These 12 pictures of the world constitute all the information we will ever have about what's out there, and from these 12 pictures, which are so sparse, we reconstruct the richness of the visual world," Werblin said. "I'm curious how nature selected these 12 simple movies and how it can be that they are sufficient to provide us with all the information we seem to need."

While scientists have known that the eye forwards several parallel representations of the world to the brain, what these are and how they are produced has been a mystery.
"What we have done," Roska said, "is show that the retina creates a stack of image representations, how these image representations are formed and that they are the result of cross-talk between layers of cells in the retina."

The results are a big step toward producing a bionic eye employing a unique computer chip that can be programmed to do visual processing just like the retina. The chip, called a Cellular Neural Network (CNN) Universal Machine, was invented in 1992 by Roska's father, Tamás Roska, and Leon O. Chua, a professor of electrical engineering and computer sciences at UC Berkeley.

"The biology we are learning is going into improving the chip, which is getting more and more similar to the mammalian retina," Roska said. "Nevertheless, a bionic eye is a far-fetched notion until someone figures out how to connect it to the neural circuitry of the brain."

Over a period of nearly three years, Roska painstakingly measured signals from more than 200 ganglion cells in the rabbit retina as he flashed pictures of a featureless square or circle. Ganglion cells are the eye's output cells, forming the optic nerve connecting it to the brain.

"We made very simple measurements on retinal cells, recording excitation and spiking when we flashed squares and moving spots in front of the eye," Roska said.

From these, he and Werblin determined that there are about a dozen different populations of ganglion cells, each spanning the full visual space and producing a different movie output.

One group of ganglion cells, for example, only sends signals when it detects a moving edge. Another group fires only after a stimulus stops. Another sees large uniform areas, yet another only the area surrounding a figure.

"Each representation emphasizes a different feature of the visual world - an edge, a blob, movement - and sends the information along different paths to the brain," Werblin said.

The two researchers shared these detailed findings with software designer David Balya in Hungary, who modeled the visual processing on a computer, a preliminary step before actually programming a CNN chip to simulate the image processing that goes on in the eye. The computer model precisely mimics the output of the ganglion cells of the retina, vividly showing the difference between the world we see and the information that actually is sent to the brain.

"We now are looking at the predictions the model makes when viewing natural scenes - Frank's face or leaves on the ground - and comparing them with what we measure in actual retinal cells, to learn how good these predictions are," Roska said.

Though scientists realize that the eye is not merely a camera providing digital input to the brain, the general consensus has been that the world projected onto the retina and detected by cells called photoreceptors got sent to the brain after some relatively simple processing.

Roska and Werblin showed that retinal cells do a lot of processing to extract only the essence of the picture to send to the brain. The anatomy of the retina is layered to facilitate this.

Light initially impinges on the light-sensitive cells of the eye, the photoreceptors, which fire off signals to a layer of horizontal cells and thence to bipolar cells. Since 1969, Werblin has been recording from all retinal cells and has detailed how each cell type processes data from the photoreceptors.

The bipolar cells funnel signals down their axons - the outgoing wires of the nerve cell - and relay them to the dendrites or input wires of ganglion cells, which send the processed information to the brain. All these cell types are arrayed in unique layers, stacked one atop the other.

Biologists noted earlier that all ganglion cells were not alike and that they fired off different information to the brain, though the details were hazy. Part of the reason is that the axons from the bipolar cells synapse with or touch the dendrites of the ganglion cells in a tangled region (the inner plexiform layer) that made biologists despair of making sense of the connections.

Roska discovered, however, that this region of tangled axons and dendrites is really laid out in orderly strata. By staining the cells from which he recorded, he found that bipolar cell axons converge on 12 or so well-defined layers, where they synapse with the dendrites of the ganglion cells. Each layer of dendrites belongs to a specific population of ganglion cells.

Without interaction between layers, though, the signal emerging from the tangle would not be much different from the original 12-channel output of the bipolar cells. The critical element is another type of cell, the amacrine cells, which send processes to the various layers of dendrites and allow the layers to talk with one another. This cross-talk is what allows the layers to process the visual data and extract the sparse information that the ganglion cells send up to the brain.

"Previously, when people studied ganglion cells, they would look at the cell and flash lights. One of Botond's major contributions to this was, he thought about this not as the cell, but as the layer of processes from which the cell is reading. So, we began to think in terms of layers, and all of the activity we measured corresponded to what happened in a particular layer," Werblin explained. "Then it became clear that these layers were actually talking to each other. Previously no one had even thought that these layers talked to one another, even though 100 years ago the picture was there. No one had really looked at that picture."

Mars Polar Lander Still not Found

Mars Polar Lander:
"NIMA researchers used high resolution imagery from NASA's Mars Global Surveyor spacecraft, now in orbit around the Red Planet, in their effort to locate the lander and its components, including a protective aeroshell, heat shield and parachute. One of the principal challenges in locating the missing lander using images from the orbiter is that the Mars Polar Lander is only somewhat larger -- about six and a half feet across -- than the smallest objects the orbiter's camera can see on the surface of Mars. In an initial analysis, NIMA researchers reviewed and assessed features seen in several images that they believe could be indicative of the lander and its protective aeroshell. An alternative view presented by NASA is that these features could be noise introduced by the camera system, so further work between NASA and NIMA will be conducted to address differences of interpretation."

Thinking Outside the Box (washingtonpost.com)

"What we should say is that copyright, like access to the airwaves, is something that brings responsibility. The government should give you copyright. But in exchange, you owe me a buck if your software crashes.

"There'd be different legal categories of software. If you want to rush it to market, and have first-mover advantage and see what happens, fine. You could label it creative software. But much of your code will be open to the public."

If you want to build a business empire, however, and you want the government to throw itself into protecting your copyrights, in Lanier's scheme you would then have to label your product "firmware."

"If you see this thing is taking off, you have the right to say: This is no longer creative software. This is functional. This has utility.

"But once you do that, you owe me a buck every time it crashes."

And the powers of Washington's enforcement tentacles would hound buggy software writers to the ends of the Earth.

"Instead of hunting down people who smoke pot, they'd be hunting down people who sell business software that crashes. They'd owe people a buck or go to jail. That's what Washington should be doing."

Aimster tells Napster file filter to 'pig off'
By: Tony Smith
Posted: 07/03/2001 at 15:04 GMT


Aimster, the Napster-across-Instant Messenger software developer, has released what it reckons is the solution to Napster's filename filtering system.


Napster now monitors the names of shared files in order to block songs for which it hasn't been given permission to allow to be shared on its network. The move is part of the company's plan to avoid being completely toasted by the music industry and the courts.


Aimster's developers reckon this is tantamount to an invasion of privacy. What you call the files on your own hard disk, whether it's shared or not, is your own business, not Napster's. Hence what they're calling the Aimster Pig Encoder, which simply shuffles around the characters in an MP3's filename while still ensuring downloaders can figure out what they are: "It takes each of the file names of the mp3 files in your Napster directory and encodes the file names so that the name cannot be easily monitored," it says on Aimster's Web site.


Aimster implores users not to let on how the name shuffling works, presumably lest those crafty buggers at Napster figure it out and block the shuffled name to.

Aimster even goes as far as to threaten anyone considering letting on the secret of the encoder with legal action under the Digital Millennium Copyright Act - irony of ironies, the same legal foundation the music biz used to swat Napster.

As we don't know how it works, we can't tell you anyway. Not that Napster coders needs us or anyone else to tell them that - they can look at Aimster's site and download the code themselves.

Of course, if they try to use it to block juggled filenames, they'll be contravening the DMCA, too, which will make for an interesting situation: Napster sued simultaneously by both the music industry and users.


The DMCA makes illegal the act of circumventing copyright protection systems. ®

Scientific American: Feature Article: Making Sense of Taste: March 2001

Flavor is a complex mixture of sensory input composed of taste (gustation), smell (olfaction) and the tactile sensation of food as it is being munched, a characteristic that food scientists often term "mouthfeel." Although people may use the word "taste" to mean "flavor," in the strict sense it is applicable only to the sensations arising from specialized taste cells in the mouth. Scientists generally describe human taste perception in terms of four qualities: saltiness, sourness, sweetness and bitterness. Some have suggested, however, that other categories exist as well--most notably umami, the sensation elicited by glutamate, one of the 20 amino acids that make up the proteins in meat, fish and legumes. Glutamate also serves as a flavor enhancer in the form of the additive monosodium glutamate (MSG).

Umami, is a new taste I have heard of before. Lets see what a search turns up for it.

GOLDEN SHOWER OF RICE
Those silly, overly emotional, anti-science luddites are at it again! The benevolent corporate overlords at AstraZeneca have gone and spent $100 million to splice a daffodil gene into white rice to create a golden colored variety of rice. But the big deal is not the spiffy new designer color but rather the beta-carotene - a nutrient the body can convert into vitamin A - produced by the new variety. And vitamin A can, in the words of the altruists, "help prevent blindness and infection in millions of children." So it's a no-brainer, right? Especially seeing how although farmers in developed countries will have to pay royalties, those in the "third world" earning less than $10K per year will not. So what can even the most unreasonable of ultra-lefty tree-huggers have to gripe about?

The Asynchronous Design Group explores the potential and works to understand the problems of the asynchronous design style. Our work to date leads us to believe that asynchronous systems offer:
Improved performance or price performance;
Reduced design cost and time through re-use of specifications and designs;
Lower power consumption because no energy-consuming transitions happen unnecessarily;
An easy upgrade path to take advantage of incremental technology improvements because different parts may run at different speeds;
and A way to reason about the correctness of a design.
