Brain scientist Jill Bolte Taylor gave this talk at TED where she showed us a real brain and how it consists of two separate halves. The right half thinks in parallel and knows the concept of “we”. The left half thinks in serial and knows that concept of “I”. One day she had a stroke on the left hemisphere and she is able to describe to us today what happened on that day as her brain functions started to shut down. She described how she lost the normal brain chatter that are always in our head, how she gained a perspective as an outsider looking at herself, and how she experienced nirvana.
