Each of us use the same basic neural pathways, yet we don’t all think the same thing. Why? Because we have different content traveling along the neural pathways.
The corpus callosum connects the two cortical hemispheres 200 million times, linking the cortical mass of 15 billion neurons. With a very broad brush, we can say that there is a comparison (with the opportunity for either side to replace its current neural summary with that of the other hemisphere) every 75 neural steps.
