I remember reading an interesting article about the mitzvah of teffilin. They had a fascinating picture of what the front of the brain looks like . In the picture it shows that their appears to be two ע that are formed in the brain. Then they show that the teffilin happen to have to be placed betweem these ע(literally bein einecha)since it is the same place as the halacha requires.
I understand this question seems strange,but after seeing the picture it will make sense. Does someone happen to know where this picture is,or knows enough about the brain that they can show any picture with these ע?
