FFAI Whole Brain Emulation

feasiblity

do we know enough?

scanning

do we have the computational resources?

roadmap

research cycle

overlap with other fields

model system

impact

subproblems

scanning

translation

simulation

(based on Sanders and Bostrom, 2008; based on workshop participants)

hypotheses

philosophical

technical

biological

These are important questions in physics, biology, and neuroscience.

The way we test hypotheses is by experiment, and for many of these hypotheses, emulation is the obvious experiment to do.

scale separation

the nervous system operates at many different scales

how do we simulate this? down to the atom? molecule? neuron?

can we describe the system at different scales? can we abstract functionality at high resolution?

we need at least one cut-off where we stop emulating greater details

observation: microstimulation (individual neurons) can produce macroscopic changes in behavior

but: in software engineering, we have many scales at which we compose software systems, yet changing a single bit somewhere can bring the whole system crashing down

Sanders and Bostrom: Brain Emulation Roadmap (2008)

(Review Article)

conclusions

whole brain scanning seems feasible

whole brain emulation is becoming feasible over the next few decades, barring unexpected upsets in the improvement of computer performance

goals

emulation vs simulation

black box

how do we know it's working?
