Can you just make a simple effect size map with + and – and no thresholding?

What's making me doubt my results is that the differences are observed in large areas of the left hemisphere, but absolutely nowhere in the right, and we have no theoretical reasons to expect such a lateralization. Do you have any ideas what might have gone wrong? I have 17 patients and 25 controls, is this maybe too small of a sample? Should I double check certain analysis steps? Basically any ideas are welcome, since I really cannot interpret these findings at all, it seems. Thanks in advance!
