    Our analog brains

    I thought this quote from Slashdot was fun:

    Roland Piquepaille writes "We're using computers for so long now that I guess that many of you think that our brains are working like clusters of computers. Like them, we can do several things 'simultaneously' with our 'processors.' But each of these processors, in our brain or in a cluster of computers, is supposed to act sequentially. Not so fast! According to a new study from Cornell University, this is not true, and our mental processing is continuous. By tracking mouse movements of students working with their computers, the researchers found that our learning process was similar to other biological organisms: we're not learning through a series of 0's and 1's. Instead, our brain is cascading through shades of grey."

    Sometimes it amazes me how long it takes for science to find out the earth is not flat when just looking at the horizon reveals that it is not.

    That what science is all about:
    Spending millions of hours and money to research are re-discover things we already know then just stick a label that says: "Approved by Science".

    More like a slide ruler than a digital computer. For those interested William Power wrote a book in the mid 70's titled Behavior the Control of Perception about the analog brain.

    Not the point. Point is you have to prove something to someone who doubt in "things we already know". That is science all about. Oh, and of course to say "Look I am more clever than rest of you people, because I am scientist"

    Ha! that explains why a slide ruler is so intuitive and awesome as a calculator!
    I love the circular ones

    Many avid slashdot readers, maybe. Anyone who's paid even the slightest attention to philosophy and neuroscience, no.

    A neuron either fires or doesn't... A 1 or a 0. There are lots of them, an they don't work sequentially but they're esentially either on or off.

    A bit like a silver halide crystal - it either get's developed or it doesn't - thats a 1 or a 0 too... (but there are lots of them arranged more inteligently than in a digital sensor).

    While it true that a single neuron is either off or on, neural pathways are comprised of bundles of neurons and it is the number of neurons that are firing (transmitting a signal) that determines the power of the signal which eventual results in a behavior or cognitive activity. The chemical process that leads a neuron to fire is also analog. In a rear instance the firing of a single neuron may start a cascade of neurons firing, but for the most part the firing of any one single neuron has has no meaning for the system. Without the development of as many silver halide crystals as are required to create a pattern that provides visual image and useful information the development of a single crystal is meaningless (in terms of creating useful information).
