Neuroscience Discovers the Tropical Zodiac


Two thousand years ago Ptolemy in his Tetrabiblos attempted to summarize the existing knowledge about astrology in the Hellenistic world.  Ptolemy, who viewed himself as a scientist and an encyclopedist, sought to put astrology on a scientific footing.  For this reason he elected a tropical zodiac based on the seasons of the year rather than a sidereal zodiac based on the constellations and subject to the precession of the equinoxes to determine the first degree of Aries, the conventionally agreed upon start of the zodiac.

Fast forward 2000 years.  Modern neuroscience is beginning to discover the implications of the tropical zodiac.   According to a recent article by Christian Jarret entitled How your season of birth is etched into your brain:

“Spiro Pantazatos, a neuroscientist at Columbia University Medical Center, has studieed links between season of birth and brain structure in healthy adults. He thinks the association between season of birth and psychiatric and behavioural outcomes later in life could be mediated by genetic factors that affect the growth of the brain.”

Dr. Pantazatos was also able to predict which season the women in his study were born under by “looking at differences in grey matter volume across their brains.”

This study reads a lot like Ptolemy’s Tetrabiblos couched in modern scientific terminology rather than the extant scientific hypotheses of Hellenistic times.  The more things change, the more they remain the same.
