- The human brain is said to have 100 billion neurons, like the number of stars in our galaxy. There is indeed a principle in alchemy - as within, so without.
It seems that each hemisphere of the brain is dominant for specific behaviours:
- the right brain is dominant for spatial abilities, face recognition, visual imagery and music
- the left brain may be more dominant for calculations, math and logical abilities.
Insider Description of a Stroke Impairing Brain Functions
Neuroanatomist Jill Bolte Taylor tells from personal experience the different roles each brain hemisphere play and what happens when a stroke begins to shut down brain functions.
During a massive stroke she felt her brain functions slip away one by one, speech, movement, understanding - she studied and remembered every moment and describes it here. This is a fascinating description of experiencing a stroke, shared by a highly trained and experienced neuroanatomist.
