Probably true. In fact watching the film Avatar where the Na'vi can connect with their environment is perhaps the best example of consciousness in action switching its focus from one part of the body to another, where their environment is their body, and the Na'vi is consciousness itself.
Our bodies are largely autonomous with cells communicating via a variety of methods either pumping in/out chemicals to the cell itself or the immune system placing protein markers for other parts of the body (immune cells) to deal with bearing in mind that every cell in the body has a complete copy of the DNA.
One thing I have learnt about the body, is there is alot of redundancy built in for it's survival, every cell has a complete copy of the DNA which can be altered leading to cells not functioning properly, and there are a variety of means in which the consciousness can be alerted to problems which need addressing like hormone's or nerve messages.
Simply dropping 500Mg of niacin (the non flush variety) on an empty stomach demonstrates how quickly the prostaglandlins can be stimulated into action in many different parts of the body, not just the skin but internal organs like the lungs & liver. How aware you your consciousness is about these changes and effects is perhaps also an indicator of your consciousness, just like some people are more aware of their food cravings.
When considering food craving's & how pregnant women can suddenly start craving things like coal when they perhaps have never eaten it before also indicates some sort of memory that may have been passed on by their parents, or maybe there is some other subconscious mechanism which perhaps through the nose enables the body to identify a substance which contains chemicals which the body needs.
The fact our taste and enjoyment of food and drink is altered simply by light also indicates our consciousness is easily swayed over the logic or remembered/imagined experience.
Ultimately its hard to define what consciousness is exactly because when considering the blood brain barrier and how hard it is for some chemicals to reach the brain but not other's, is our consciousness largely just a collection of learned experiences where nature has utilised cholesterol into a storage medium and consciousness itself is just a memory of chemical & electrical responses in a variety of cells which certain feedback mechanisms like nerves, immune system cells and hormones the brain is able to remember and influence its behaviour as a result?
