If you are planning on getting this article and reading it, be warned....it is incredibly technical. That being said, let me give you a quick summary. The researchers observed that there were significant differences in three critical regions of the brain:
- The thalamus (the region for sensory inputs)
- The corpus callosum (which connects the two cortical hemispheres)
- The cingulum which connects the cingulate cortex with another cortical region (the entorhinal cortex) that is is involved in the processing of memories.
- The major issue is that higher anisotropy was seen in these areas in men when compared to women. In layman's terms, the brain circuit's insulation in these regions are thicker which might indicated being more 'hardwired' or that these circuits are carrying a heavier neurological load. This is where interpretations can go in any number of directions.
It will be interesting to see how long it takes the media to get hold of this and how the research community responds to it.
