The âHuman White Balanceâ in the Brain. Human visual perception does not work like a technical measuring instrument that projects signals from the eyes on some kind of âmonitorâ in the brain. The pictures we perceive are created in the brain and after the brain has compared the signals from the eyes with known patterns and colors.
Sense of balance. Sense of balance or equilibrioception is one of the physiological senses related to balance. It helps prevent humans and animals from falling over when standing or moving. Balance is the result of a number of body systems working together: the eyes (visual system), ears (vestibular system) and the body's sense of where it is in space (proprioception) ideally need to be intact.
