Редактирование: Cryonics revival (раздел)

== Whole Brain Emulation ==

''See [[Whole brain emulation]]''

This approach to cryonics takes the ideas of information-theoretic death and the central tenets of [[Whole brain emulation]] (Memory and personality are stored in the brain, consciousness arises from material processes, et cetera) and proposes that [[#Patients|cryonics patients]] may be revived by scanning the connectivity and properties of the cells in their brains (For example, with an [[ATLUM]] or some form of high-resolution tomography); and that an abstract, computer model of these properties will be very similar to the person who was cryopreserved.

=== Process ===

# The vitrified brain is extracted from the patient. Necessary extra fixatives are applied.
# The brain is segmented into as many pieces as needed.
# Each piece is laminated and scanned by a cryoultramicrotome, [[ATLUM]] or some other machine.
## Current technology is rather slow, but new massively-parallel electron microscopes are being, developed, primarily by the semiconductor industry. The speed of scanning depends on how many machines you have.
# A stack of electron micrographs is built, one for every slice.
# Noise is eliminated, different electron micrographs at the same height are pasted together by inferring edge connectivity.
# An edge detector traces the contours of neurites and cellular structures.
# Other algorithms detect intracellular structures of interest (Polyribosome complexes).
# This is done for every layer.
# Another algorithm joins the edges in different layers, creating a 3D model of the brain.
# Another algorithm uses that model to create a graph of the connectivity of the brain. Each node in this graph is a neuron, and the neuron data structure is supplied with all the necessary extra information acquired by step 7.
# After the scan is complete, the graph is stored in a neuromorphic computer; a machine where every processor is a hardware implementation of some model of neurons.
# The graph at the lowest level of the stem is joined with a species-generic graph of the connectivity of the spine, ie: Axons of the brain are matched to virtual nerve endings.
# The simulation of the body and brain, either connected to a robot or virtual avatar, is started.
