More may have been learned about the brain and the mind in the 1990s - the so-called decade of the brain - than during the entire previous history of psychology and neuroscience.
Consciousness, much like our feelings, is based on a representation of the body and how it changes when reacting to certain stimuli. Self-image would be unthinkable without this representation.
Having a self, even a simple self, allows you to look into the world and put a mark over what is more important and less important. It's a way of classifying the world in terms of your own needs.
Some of us, for better or worse, develop very stable, consistent, and largely predictable machineries of self. But in others, the self machinery is more flexible and more open to unexpected turns.
Of necessity, the autobiographical self is not just about one individual but about all the others that an individual interacts with. Of necessity, it incorporates the culture in which the interactions took place.
I got interested in the emotions after studying patients who had lost the ability to emote and feel under certain circumstances. Many of those patients also had major impairments in their ability to make decisions.
Emotion consists of a very well orchestrated set of alterations in the body that has, as a general purpose, making life more survivable by taking care of a danger, of taking care of an opportunity, either/or, or something in between.
If I use the word consciousness, in our lab, in our institute, what we mean is the special quality of mind, the special features that exist in the mind, that permit us to know, for example, that we, ourselves, exist, and that things exist around us.
When we talk about emotion, we really talk about a collection of behaviors that are produced by the brain. You can look at a person in the throes of an emotion and observe changes in the face, in the body posture, in the coloration of the skin and so on.
You can be highly concentrated on a person, on a problem, and be so good at excluding all other material that that becomes not just the focus of your experience, but practically the sole content of your experience, everything else falling by the wayside.
When you deal with something like compassion for physical pain, which we know is very, very old in evolution - we can find evidence for it in nonhuman species - the brain processes it at a faster speed. Compassion for mental pain took many seconds longer.
