Each brain is exposed to different circumstances. It's very likely that your brain is unique in the history of the universe.

Since the idea that modification of synaptic function can provide a basis for memory arose shortly after the first anatomical description of the synapse a number of models (Hebb 1949 . . Hayek 1952 . . Kendel 1981) have been proposed in which various cognitive activities are represented by combinations of the firing patterns of individual neurons.

Many cognitive psychologists see the brain as a computer. But every single brain is absolutely individual, both in its development and in the way it encounters the world.

We're inquiring into the deepest nature of our constitutions: How we inherit from each other. How we can change. How our minds think. How our will is related to our thoughts. How our thoughts are related to our molecules.

Consciousness allows you the capacity to plan.

A knowledge of brain science will provide one of the major foundations of the new age to come. That knowledge will spawn cures for disease, new machines based on brain function, further insights into our nature and how we know.

Your brain develops depending on your individual history. What has gone on in your own brain and its consciousness over your lifetime is not repeatable, ever - not with identical twins, not even with conjoined twins.

Most theoretical work since the proposals of Hebb (1949) and Hayek (1952) has relied upon particular forms of dependent synaptic rules in which either pre- or postsynaptic change is contingent upon closely occurring events in both neurons taking part in the synapse.
