While there are more neural connections within a half brain than between the two halves, there are still massive connections across the hemispheres. … - Michael S. Gazzaniga
" "While there are more neural connections within a half brain than between the two halves, there are still massive connections across the hemispheres. Even so, cutting those connections does little to one’s sense of conscious experience. That is to say, the left hemisphere keeps on talking and thinking as if nothing had happened even though it no longer has access to half of the human cortex. More important, disconnecting the two half brains instantly creates a second, also independent conscious system. The right brain now purrs along carefree from the left, with its own capacities, desires, goals, insights, and feelings. One network, split into two, becomes two conscious systems. How could one possibly think that consciousness arises from a particular specific network? We need a new idea to cope with this fact.

Robert Sapolsky, professor of neurology at Stanford, makes the extremely strong statement: “It’s boggling that the legal system’s gold standard for an insanity defense — M’Naghten — is based on 166-year-old science. Our growing knowledge about the brain makes notions of volition, culpability, and, ultimately, the very premise of a criminal justice system, deeply suspect.
When shown a series of photographs of five natural landscapes — tropical rain forest, temperate deciduous forest, coniferous forest, savanna, and desert — the youngest subjects (those in the third and fifth grades) picked the savanna as a preferred landscape. Older subjects equally preferred those landscapes with which they were familiar, as well as the savanna.52 People were happier viewing scenes with trees rather than inanimate objects, and also preferred the shapes of trees with spreading canopies, similar to those found on the African savanna, rather than rounded or columnar ones.
