Whole Brain Emulation
We consider a strategy of straightforward duplication of the activity, and look at the numbers of some of the components. The human brain has up to one hundred billion (10^11) neurons and between one hundred trillion (10^14) and one quadrillion (10^15) synapses. But we have reached a point where for purposes of data acquisition these objects are now considered fairly large (e.g. 200 nm to 2,000 nm for synaptic spines and 4,000 nm to 100,000 nm for the neural soma), at least by the standards o...From Randal A.

Brainscans as a Form of Identification
Brainprint scans are considered the definitive method for identifying egos. Contrary to popular misconceptions, the term “brainwave scan” is a misnomer, as this form of identifier is not based on simple electroencephalography (EEG: a reading of the electrical activity created by neurons firing within the brain). The actual process for recording brainprints for identification purposes goes much deeper than that. It is based on the electrophysiological responses (event-related potentials) t...The problem is that they must be updated regularly because the brain is always changing.
