Hi,
I found this information quite interesting.

The human consciousness is our spirit self which is an eternal identity. We tend to think of it as our human intellect which goes away when the body stops working.
Being human requires us to work with our brain to do just about everything. So for sure it is very important. However getting it to work with our spirit self can be an issue. I guess the logical brain does not know, because we do not teach it, that there are aspects of us which are eternal and that it can contribute to that aspect of self, or not.
I suspect that science will eventually teach us a great deal about spirituality.
