ABSTRACT
In 1314, at the age of forty-nine, the Italian poet and son of an exchange broker Dante Alighieri published his Inferno, which contains one of the most impressive descriptions in existence of limbo (Lewis, 2002). In 1952, at the age of thirty-nine, the American neuroscientist and son of a Presbyterian minister Paul Donald MacLean coined the term limbic system to refer to some components of the central nervous system. It took six hundred and thirty-eight years to provide a semantic link between the gates of hell and a part of the brain.
