idiot savant

[Michael Sylvester]

 it is assumed that some of those individuals
have brain parts that are overdevelopped (hence
their mathematical ingenuity) and other parts
underdevelopped.
How true is this? Is there a way to explain how they
do it?
Btw,why are most of these reported idiots savants appear
to be male?
