The different political systems, religions and social habits demonstrate that the same brain can be tuned in different manners. But the tuning capacity is limited. We can never feel as a jaguar, for example. We can imagine a man who believes or who intends to be a jaguar, but to intend is not the same as to be. We can have other ideologies, but we will continue restricted by the nature of our brain and of our body.

The future of human relationships will be directly related to the cerebral functions. For this reason it is already a fundamental thing. In the past, and well until today, some South American countries have had a great neuropharmacological history, since the natives' times. It is necessary that we remind ourselves of the many licit and illicit drugs that were generated in our continent and that act on the brain.

Structurally we should understand that one cannot think that the human brain is different from the brain of the other vertebrates. It is an important question, because we can investigate what is the difference between the brain of a mouse and ours, and of course the difference is enormous, in size and capacity.

Language changes only those aspects of our consciousness which are based on information, but not the feelings themselves. The words are as stones that can cause wounds or as caresses that becalm and that guide us, but the content of consciousness is intrinsic.

We assume that we have free will and that we make decisions, but we don't. Neurons do. We decide that this sum total driving us is a decision we have made for ourselves. But it is not.

We no longer see the evolution of the nervous system, but that of a certain individual. The role of the memory is very important but... not as important as we believe. Most of the important things that we do don't depend on memory. To hear, to see, to touch, to feel happiness and pain; these are functions which are independent of memory; it is an a priori thing. Thus, for me, what memory does is to modify that a priori thing, and this it does in a very profound way.
