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.

We're seeing it the same way, we're hearing the same way, we have the same conception of the situation. And so, for all purposes, we are operating with a very similar perception.

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.

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.

Narratives are not fixed. We change our narratives for ourselves and we change them not necessarily deliberately. In other words, some people do, some people will constantly reconstruct their biography for external purposes, it's a very interesting political ploy.

All of that is constantly operating when you not only learn, but when you recall. But as you recall in a different light, the weights with which something is more probably going to be or not recalled on the next instance, are going to be changed. So you're constantly changing the way, for instance, synapses are going to fire very easily or not so easily.

The autobiographical self is built on the basis of past memories and memories of the plans that we have made; it's the lived past and the anticipated future.
