Famous astronomer Carl Sagan describes the triune theory of brain proposed by Paul D. Maclean. In his characteristic style of presentation that he used to popularize Astronomy Carl Sagan goes over the functions of the different parts of brain by walking around a giant replica of human brain.
He concludes his presentation by elevating the role of cerebral cortex which provides us with the flexibility of thinking functions and allows us to override the instinctual programs that are coded into our genes.

I have enjoyed watching Carl Segan's videos and this is no exception. You find his approach very positive and friendly.
Indeed to share my views on this topic, from the scientific point of view the following types of scientists can collaborate on human brain consciosuness problem.
Only then can we get a simplified solution
1. Neuroscientists who have a good knowledge of the brain
2. Psychiatrists for their immense knowledge and study of the variety of humans and their behavior.
3. Computer Scientists for their understanding of programs and instruction sequences and for trying to chart the brain instructions into categories and mapping them onto a computer model which can be studied and experimented easily.
4. Scientists with deep rooted knowledge of animal king dom and botanists who undestand the plants, microbiologists for their understanding of cellular processes. Plants are an interesting area of study as they can be experimented easily and because they exhibit a sort of awareness characteristic of living creatures without the human brain.
5. Finally spiritual men with deep meditation experience and who have exhibited skills of being able to minimize their mind and brain activity to the point of almost being motionless.
The need of the hour is to simplify the problem model and eliminate possibilities and the best specimen to study for this is not humans with brain but creatures that show some degree of consciousness without exhibiting a complex nerve system.
I have explored some of these ideas in my blog
