I suppose that the number of neurons that are working on a problem at a moment will have to expand exponentially based on the number of synaptic connections per neuron as well as the number of hits/misses per neuron that are receiving the signals, viewed as if an expanding light-cone sphere in the brain (it's of course, a neural activity cone / sphere, not light). I am sure this rate can be made into a model. - Bryan ----- This list is sponsored by AGIRI: http://www.agiri.org/email To unsubscribe or change your options, please go to: http://v2.listbox.com/member/?member_id=8660244&id_secret=73877309-9727c9
