"""Einstein's brain weighed 1230 grams. 1300 grams falls into the range of a normal brain. Therefore Einstein's brain was 90- to 95% of normal not three quarters or 75% of normal."""
Kozachka[sp] said that .... "Einstein's brain weighed 1,230 grams, which is less than the average adult male brain (about 1,400 grams)," .... which is somewhere in between your figure and mine, but I let's not squible.
The fact remains that if you took out 75% of Einstein's itsy-bitsy brain, his brain function would still probably be better than both of ours put together.
So Terri had half a brain. She was able to breathe on her own and had normal sleep patterns. She was incapable of being mean and nasty; she was better than all of us. She was a joy to her mother and she was the apple of her father's eye. And they killed her. Bottom line.
