On can not reduce everything to chemicals and numbers.
However note the point that they have found a zone which exists that perceives and records individual with reference to Space.
But nobody has defined Space, they have described it.
Consciousness is beyond Mind.
Activity of the Brain is Mind.,which is like a CPU, for storing information.
Higher level is Intellect which sorts out, discriminates and adds judgements ,Right or Wrong.
Still higher level is Chitta which directs the intellect, which is determined by Dispositions that are inborn.
Note that in all these activities and whatever we do, including what I write now, I am aware and observing what I am doing.
This awareness at all levels of activity, whether physical or mental is beyond these states.
Also we are aware of dreams in Dreams and in some cases we recollect.
In these experiences we observe and participate as well
Consciousness is a part Human activity in all human behavior ,yet beyond it.
A new study uses creative engineering to unravel brain mechanisms associated with one of the most fundamental subjective human feelings: self-consciousness. The research, published in the April 28 issue of the journal Neuron, identifies a brain region called the temporo-parietal junction (TPJ) as being critical for the feeling of being an entity localized at a particular position in space and for perceiving the world from this position and perspective….
“Our results illustrate the power of merging technologies from engineering with those of neuroimaging and cognitive science for the understanding of the nature of one of the greatest mysteries of the human mind: self-consciousness and its neural mechanisms,” concludes Dr. Blanke. “Our findings on experimentally and pathologically induced altered states of self-consciousness present a powerful new research technology and reveal that TPJ activity reflects one of the most fundamental subjective feelings of humans: the feeling that ‘I’ am an entity that is localized at a position in space and that ‘I’ perceive the world from here.”
Psychology and neuroscience have made major progress in explaining many kinds of thinking such as problem solving, learning, and language use. But many people still have the intuition that, no matter how far cognitive science progresses, it will still be unable to deal with the mystery of consciousness. On this view, we all have a basic understanding of conscious experience from our own episodes of perception, sensation, emotion, and reflection. But there is an unbridgeable explanatory gap that prevents science from drawing consciousness within its scope.
