Hailing from the Bahia Blanca[1] in Argentina, Dr. Aguayo graduated in medicine from the National University of Córdoba.
In the year 1967, McGill University appointed Aguayo as assistant professor in the department of Neurology and Neurosurgery.
Aguayo and his team were the first to demonstrate that nerve fibres that are located in the central nervous system and the brain of a mammal are capable of restoring themselves after considerable damage and/or injury.
Even though Aguayo was highly skilled in clinical neurology, he decided to pursue his passion in experimental studies, focusing his research in neurobiology.
In 1988, Aguayo received the Canada Gairdner International Award For the discovery of the regrowth of neural connections being possible in injured mammalians' central nervous systems.
