I recently learned about left and right hemisphere brain damage. Under these categories a condition called left brain neglect, which is from the result of right hemisphere brain damage.
This causes someone to completely neglect the life side of life, from not brushing the left side of their hair to not acknowledging someone in their left peripheral vision. This is just one of the side effects apart from memory, critical thinking.
This video shows the left neglect in a dog, which would be the exact thing in a human. I find this fascinating for the reason that this has nothing to do with their sight, hearing or smell. It is completely neurological.
