No forgiveness needed.  Welcome to the chat!

Well...there is one option with today's technology, but it'd be heck of
impractically expensive for a human brain, though I hear something like
this might be being done with insect brains.

Map out and simulate each neuron, one by one.  Make a good enough (which
likely requires near-perfect in practice) software simulation of the
neuron, including its synapses (its inputs and outputs).  Connect these
neuron simulations together, in the exact same fashion as the actual
neurons are connected.  Run the whole thing on a powerful enough computer -
which involves massive parallelism, even for insect simulations, thus the
expense.  There also needs to be blank/spare/extra hardware to simulate
growth of new neurons over time (not as many as already exist in the
running brain, but a nonzero amount, with a potentially indefinite cap if
the simulated brain lives forever; more hardware can be added over time to
support this, but this might put a cap on the practical maximum speed-up if
the uploaded brain is to run significantly faster than the original).

This misses input from the rest of the body, but it's a start (and can help
narrow down exactly what the rest of the body's inputs are).
