Savants are a remarkable mystery in the world of Neuroscience. They are generally autistic, and they usually have an IQ rating that doesn’t exceed 25.
They often have a limited ability to read or write, and many of them are institutionalized because of their inability to properly socialize with other people.
But they are being rigorously studied because of their special, even superhuman abilities that seem to emerge from some unknown dimension of their functionally inferior neuro life.
