“We must consider what we mean when we say that the spiking activity of a neuron 'encodes' information. We normally think of a code as something that conveys information from a sender to a recipient, and this requires that the recipient 'understands' the code. But the spiking activity of every neuron seems to encode information in a slightly different way, a way that depends on that neuron's intrinsic properties. So what sense can a recipient make of the combined input from many neurons that all use different codes? It seems that what matters must be the 'population code' - not the code that is used by single cells, but the average or aggregate signal from a population of neurons. In a now classic paper, Shadlen and Newsome considered how information is communicated among neurons of the cortex - neurons that typically receive between 3,000 and 10,000 synaptic inputs.They argued that, although some neural structures in the brain may convey information in the timing of successive spikes, when many inputs converge on a neuron the information present in the precise timing of spikes is irretrievably lost, and only the information present in the average input rate can be used. They concluded that 'the search for information in temporal patterns, synchrony and specially labeled spikes is unlikely to succeed' and that 'the fundamental signaling units of cortext may be pools on the order of 100 neurons in size.' The phasic firing of vasopressin cells is an extreme demonstration of the implausibility of spike patterning as a way of encoding usable information, but the key message - that the only behaviorally relevant information is that which is collectively encoded by the aggregate activity of a population - may be generally true.”

“When people are just drifting along the tides of life and can’t see the shores of reality anymore, they may experience someday the irresistible desire for a liberating burst, emerging deeply from the inner self and disentangling them from their manufactured pattern. That day might be a day of all possibilities and make them ready to hit the ground running. ("A change of vision" )”

“Every unique thing in nature is related to the whole, and partakes of the perfection of the whole. Each particle is a microcosm, and faithfully renders the likeness of the world. In geometric harmony of the cosmos there are ways that resemble, there are universal patterns, from blood vessels, to winter trees or to a river delta, from nautilus shell to spiral galaxy, from neurons in the brain to the cosmic web. A whole universe of connections is in your mind – a universe within a universe – and one capable of reaching out to the other that gave rise to it. Billions of neurons touching billions of stars – surely spiritual.”

“Just as learning to produce phonologically contoured speech and learning to hear it as such are interrelated aspects of a single task, so, too, learning to creatively project words into new contexts and to grasp the projections of those same words by others into new contexts are two aspects of a single task. What can be hard to see here is that these two pairs of interrelated capacities - to hear and produce potentially significant phonemes, on the one hand, and to detect and to project a pattern of use, on the other - are themselves no less intertwined.”

“Saw'?" Rand said. "Well, I don't suppose you'll go running to the Children. Not considering who your traveling companions are. The Whitecloaks wouldn't like what I do any more than they like what she does." "I don't understand." "She says I see pieces of the Pattern. " Min gave a little laugh and shook her head. "Sounds too grand, to me. I just see things when I look at people, and sometimes I know what they mean. I look at a man and a woman who've never even talked to one another, and I know they'll marry. And they do. That sort of thing. She wanted me to look at you. All of you together.”
