[Eeglablist] Strange mirror-image components

[Hamish INNES-BROWN]

Hello all, I have just come across some strange ICA components, and I'm wondering if anyone can help explain them. The first four components in more than one of the current batch of subjects are generally these weird mirror images of each other. Below are the first four component maps, and their ERPs....  They all have pretty strong peaks at about 10Hz as well.

What can it all mean? Hopefully not a tear in the universe (sorry).
