A new study has found another way in which male and female brains differ. It seems that when the brain is at rest, it is the right amygdala that is more active in men, and the left amygdala in women. Moreover, the brain regions they form connections to are different. The findings may shed light on why gender-related differences exist in certain psychiatric disorders and how to treat a variety of illnesses.

And an intriguing new study into the "Aha!" experience reveals that the distinct patterns of brain activity leading to such moments of insight begin much earlier than the moment itself. Prior to such moments, the pattern of brain activity suggests that the person is focusing attention inwardly, is ready to switch to new trains of thought, and perhaps is actively silencing irrelevant thoughts. This study may eventually lead to an understanding of how to put people in the optimal "frame of mind" to deal with particular types of problems
