Assuming mechanism, and some relatively high substitution level, the
answer is no.
will there be different solution at different environments ?
There is no reason. The environment can only play a role through
interaction, or interference, but this will not occur in the
situation
that you are describing.
1)then the converse should also be true right?that our thoughts don't
affect our environment..?
You are right. But only in the setting that you describe, where a
person is isolated from the environment.
This seems to me rather obvious, so I might be missing something.
in that case,what about noetic sciences ? Are you suggesting it
doesn't exist at all ?
It exists, and is fundamental. I argue that if we accept the mechanist
hypothesis, then the noetic constitutes the fundamental science(s). I
provide the math from extracting both quanta and qualia from the
noetic. Physics continue to exist, but is a a study of an emerging
mind invariant.
I remind that materialism (even weak materialism: the doctrine that
primitive or primary (aristotelian) matter exists is logically
incompatible with Occam and Mechanism, despite many materialist
believe the contrary.
2)will gravity(acceleration of the particles in brain) affect the
solution ?
As far as the local computations made by the brain are well described
at the level of particles interactions, gravity is playing a role, no
less than electromagnetism or any other forces describing (locally)
its current brain state evolution.

2.consider an artificial brain fed with signals similar to normal
brain and (for arguments sake )this artificial brain and a normal
human brain have computational similarities...then will they have
similar response? or as they are made of different materials there
would be differences in response ?
It really depends on the mechanist assumption and the choice of the
substitution level. The mechanist assumption just assumes the
existence of a substitution level where you are Turing emulable. If
the level is very low, the "environment" might be a part of your
"generalized brain", and it is logically possible that you have to
describe it at the Planck scale or below, but most neurophilosophers
and physician believe that the generalized brain *is* the biological
brain.
The 'reversal consequence' of Digital Mechanism does not depend on
the
substitution level. It depends only on the existence of such a level.
