It is essential to understand our brains in some detail if we are to assess correctly our place in this vast and complicated universe we see all around us.

It has not escaped our notice that the specific pairing we have postulated immediately suggests a possible copying mechanism for the genetic material.

Free will is located in or near the anterior cingulate sulcus.

Consciousness is somehow a by-product of the simultaneous, high frequency firing of neurons in different parts of the brain.

It is notoriously difficult to define the word living.

It seems likely that most if not all the genetic information in any organism is carried by nucleic acid - usually by DNA, although certain small viruses use RNA as their genetic material.
