Subjectively speaking, that's of course too small a time for anything
to happen. On the objective level, however, millions and millions
of neurons can begin firing, or (others) end up dumping chemicals
across a synaptic cleft to another neuron.

Here is the context of the discussion I was having with Jef.  He had
written

And so since he had said that similarity works as a criterion for
personal identity (or something like that) for duplicates at t=0 (where
that is to be understood as the instant at which a duplicate is spawned),
then I was asking him, in effect, why similarity would not be a good
criterion for t = 0.0001 second. In other words, one extremely good
argument that a person and his duplicate are the same person is that
they are so similar, because no significant change can happen that
could turn someone into a different person in so short a time (under
ordinary circumstances).
