Editing Mind uploading (section)

=== Scanning and mapping scale of an individual ===
When modelling and simulating the brain of a specific individual, a brain map or connectivity database showing the connections between the neurons must be extracted from an anatomic model of the brain. For whole brain simulation, this network map should show the connectivity of the whole [[nervous system]], including the [[spinal cord]], [[sensory receptor]]s, and [[muscle cells]]. Destructive scanning of a small sample of tissue from a [[mouse brain]] including synaptic details is possible as of 2010.<ref>{{cite web|title=New imaging method developed at Stanford reveals stunning details of brain connections|date=21 December 2009 |url=http://med.stanford.edu/news/all-news/2010/11/new-imaging-method-developed-at-stanford-reveals-stunning-details-of-brain-connections.html|publisher=Stanford Medicine}}</ref>

However, if [[short-term memory]] and [[working memory]] include prolonged or repeated firing of neurons, as well as intra-neural dynamic processes, the electrical and chemical signal state of the synapses and neurons may be hard to extract. The uploaded mind may then perceive a [[memory loss]] of the events and mental processes immediately before the time of brain scanning.<ref name=Roadmap/>

A full brain map has been estimated to occupy less than 2 x 10<sup>16</sup> bytes (20,000 TB) and would store the addresses of the connected neurons, the synapse type and the synapse "weight" for each of the brains' 10<sup>15</sup> synapses.<ref name=Roadmap/>{{Failed verification|date=March 2012}} However, the biological complexities of true brain function (e.g. the epigenetic states of neurons, protein components with multiple functional states, etc.) may preclude an accurate prediction of the volume of binary data required to faithfully represent a functioning human mind.
