Functional Networks

Was reading a book in the D-block library today. Some brain-memory book, will tell you the name next time I edit this blog.
A pretty fantastic idea was expressed in it or so I believe. That it would be wrong to think of brain memory on the lines of computer based memory. Computer based memory has an "address" element attached to it. But a brain "memory" is functional.
By functional I mean that say in response to an external stimulus an individual has say two different reactions and the reactions are such that they require the usage of motor neurons. Each reaction will have a motor neuron firing pattern. The decision as to which of these two motor neuron bunches is fired will rest upon input from common node or a branch point. The memory read operation is thus integrated with its actual implementation or the final outcome.
The decision as to which bunch gets fired at a given time is clearly determined by the strength of the connection to this node. Beauty is this strength of connection is experience modifiable.
But hey, it was just a model...experiments might show an extremely strange picture. Plus this is a Saturday evening blog post :D
You never know.

. . .

I guess I didnt have anything else to post. Sometime back I downloaded the E.coli genome sequence and placed the fasta file on my desktop for my amusement. Whenever I looked at that file I could not help but smile in my mind and nod slightly at the screen. Here is an organism - a bacterium frozen in a text document. Life cannot get more digital...



*only 1% sequence was posted, posting the whole genome would freeze the browser.
