Experiments in this new field, such as the studies of "
split-brain" patients discussed in the previous column, proved at once so thrilling and disturbing that age-old existential questions were re-ignited.
of California-Santa Barbara) describes how several animal and human
split-brain studies led him to change his long-term view on mind/brain interactions.
Such
split-brain patients were studied by Roger Sperry and Michael Gazzaniga at Caltech in the early 1960s.
The scientist said, "You are seeing the
split-brain in action"
The Greed inside this person is like a parasite living within his brain, and it's speaking with the first person "I".--I think this is a particularly Freudian concept, renewed by the
split-brain studies by Gazzaniga, and Society of Mind theories by Minsky, etc.
Through studies with "
split-brain" patients (whose two hemispheres could not communicate with each other due to a severed corpus callosum), he discovered that the human brain has two very different ways of thinking.

For instance, Lowe ignores philosophical debates over the unity of consciousness that focus on
split-brain cases.
I have presented just a small sample of
split-brain studies showing that consciousness is not totally divided in these patients.
Os best-sellers de autoajuda cerebral reproduzem e exploram o 'boom' do cerebro direito, que tem lugar a partir dos anos 60 (invertendo a tradicional valorizacao do hemisferio esquerdo), no contexto da contracultura e das pesquisas sobre o 'cerebro dividido' (
split-brain) de Bogen, Gazzaniga e Sperry, entre outros (Harrington, 1987; Gazzaniga, 2005, 1985, 1973; Harris, 1985, 1980; Blakeslee, 1980; Bogen, 1977, 1973; Gazzaniga, Bogen, Sperry, 1962).
Perhaps best-known for his work with '
split-brain' patients that showed that the right and left brain hemispheres have differing functions, Gazzaniga (SAGE Center for the Study of the Mind, U.
From the studies of the
split-brain, the left brain is more dominant for linguistic abilities, calculations, and math and logic abilities, where the right brain is more dominant for spatial ability (Oono 1996), and it was also reported that the language center of most right-handed people is on the left side of the brain (Kubota 1982; Sakano, 1982).
