...consciousness is merely electrons passing from neuron to neuron, could all matter be in some sense conscious? All matter exhibits energy transfer of some type. Could the entire universe be conscious and yet unaware of it, just as the living individual cells in our brains, which have cellular consciousness, are unaware of the whole of the human organism? There are cycles within cycles and levels within levels. STEVEN SWITZER Philadelphia...
STEPHEN HAWKING, proving (once more) that a debilitating motor neuron disease is no match for sheer will, plans to marry again, according to the London Telegraph. His bride will be his erstwhile nurse--once married to the designer of his voice synthesizer. Hawking divorced his first wife in 1991 after 26 years of marriage...
...running on four cylinders -- and after 30 or 40 years, that can take its toll. "Everything has a finite life-span, from a car engine to the human heart," says Dr. Lauro Halstead, director of the postpolio program at the National Rehabilitation Hospital and a polio survivor. "A motor neuron is no different. Neurons that normally drive 20 muscle cells in the polio patient may now have to supply up to 2,000 muscle cells. Basically, this is a demand that the motor nerves are not designed to sustain...
...described the relationship between his model and the actual brain: "We are trying to use biological findings of neuron responses to create a mathematical model." He said the model simulates the activity of brain cells...
Contemplate for a moment a tangle of seaweed tossed up on the shore. This is what a neuron looks like, surrounded by a thicket of tiny tendrils that serve as communications channels. Now multiply that neuron 100 billion times. Crammed into the skull of every human individual are as many neurons as there are stars in the Milky Way. Each one of these receives input from about 10,000 other neurons in the brain and sends messages to a thousand more. The combinatorial possibilities are staggering. The cerebral cortex alone boasts 1 million billion connections, a number so large, marvels...
