<p>so according to mainstream view brains are completely deterministic given initial conditions and knowing all the external input, and free will doesn't exist. so has there been attempts to predict human/advanced animal behavior from a given initial brain state? i mean accurately predicting movement of limbs and words spoken and facial expression for many minutes, not just predicating a sad brain is going to cry.</p>

I think you are mixing up a bunch of different concepts. There are a bunch of different [neural coding schemes](https://en.wikipedia.org/wiki/Neural_coding) and many of these include a non-deterministic component (or require the state to be specified at the/molecular/atomic level).

This is more of a philosophical question (or possibly a physics one) about what is and is not deterministic. https://philosophy.stackexchange.com/questions/45662/can-i-predict-my-future-by-observing-all-humans-events is an example. See also https://en.wikipedia.org/wiki/Laplace%27s_demon I am not aware of a "mainstream view" that "brains are completely deterministic" so I'd also be curious where that view is coming from.
