The lopsided brain: Attention bias is shared by humans and birds

...uffered injury to the brain's right hemisphere can experience a much more severe bias in their spatial attention--spatial hemineglect--in which the entire left side of the visual world seems nonexistent as the brain performs spatial tasks. In a classic example, a patient asked to draw a daisy can only manage to...
