the explanation is simple -- the image of the spinning girl is ambiguous to your brain. you can see her spin either one or the other way, or both ways by alternating between them. all of these are equally valid interpretations and have no implications on brain function. i see her spin both ways as well, and i can switch between CW and CCW spinning.
the spinning girl is nothing more than a dynamic version of these pictures:
whether you initially see a vase or faces, both are valid. whether you see a small cube in a 3-walled frame or a large cube with a chunk the size of a smaller cube cut out of it, again both are valid. and whether the last cube has its front face on lower left or upper right, both are equally valid perceptions.
the brain finds all of these interpretations equally valid, although mutually exclusive. your perception will spontaneously alternate between the two options because they are exclusive.
that's all there is to it. no implications to brain lateralization is involved. people misuse these 'tests' (perceptions) to invent identity where there is none. that's the explanation for popularized representation.
i quess you cannot see the lady spinning to both direction at the same time you see it in the beginning. it is not which way the lady is spinning after some time, it is which side dominates "right now" and which side dominates more whenever you check the lady. when you stare it you start using your brains more and the lady may start spinng to the opposite direction. testing is based on the first impression, not letting your imagination affect and "forcing" your brains see to what you want to see.
but it is interesting to test the spinning lady after some hard differend kind of works: behave like an artist and be creative and sensitive.. check the lady... then solve hard math problems, and check the lady again. =} sometimes it works, sometimes you see the lady spinning always the same direction during the first seconds.
