Sometimes the most amazing abilities of the human brain are revealed exactly when things go wrong with it. Take, for example, savants – people who have mental abilities that could only be characterized as superhuman (like having photographic memory, playing music perfectly after hearing it just once, or doing complex mathematical calculations in one’s head) but otherwise severely disabled in every day cognitive functions and social interaction.

Does the human brain have latent savant-like abilities? Does our higher cognitive functions somehow block these abilities, and why? And can we have savant-like abilities without the accompanying autism and/or developmental disabilities? One intriguing study by Dr. Allan Snyder of the Centre for the Mind suggested that temporarily impairing the left fronto-temporal lobe in healthy subjects by low-frequency magnetic pulses could result in savant-like mental abilities (see, for example: article in New York Times “Savant for a Day“)

Most savants are born with their abilities (and unfortunately, their developmental disorders), but not all: severe brain injuries can, in very rare instances, cause savant-like abilities to surface (see, for example: The Case of the “Sudden” Savant). One noted savant (Daniel Tammet, see below) is a highly functioning autistic savant who can perform amazing mental feats but does not have significant developmental disabilities.

There are a few savants in the world (called “prodigious savants”) whose abilities are so exceptional that they would’ve been classified as phenomenal with or without cognitive disabilities. Let’s take a look at 10 savants with superhuman mental skills:
