The right hemisphere is sustained, broad, open, vigilant, and alert. It is always on the look out for things different than our expectations. It understands implicit meaning, body language, metaphors, and context. It understands that nature is never fully graspable, never fully known, McGilchrist said.
According to psychiatrist Iain McGilchrist, the left hemisphere gives narrow, sharply-focused attention to detail, and helps us grasp language and concrete ideas. The left brain yields clarity and focus, so when we know something is important and want to be precise about it, we use our left hemisphere.
