Churchlands

This semester I am taking a dreaded class in the Philosophy department at SEMO: Mind, Meaning and Value. It is a course that explores current neuroscience which basically reduces all of our human-ness to brain activity, doing with away with any dualistic concept of some non-physical entity which drives the body and which could, possibly, survive death.
First of all, it should be stated that setting parameters that only observable (i.e. physical) evidence should be used would end in a thoroughly materialist conclusion. What else could they come up with? It is interesting, however, that contemporary physicists and astronomers can postuate the existence of undetectable objects, dark matter, and alternate universes without an apparent contradiction with the tenets of science.
Also, as I hear often that Orthodoxy is less dualist or even not dualist at all, I wonder how the Orthodox Church would view it if science reduced humanity to brain patterns, chemicals, and electric charges.
Any ideas? Please comment.
