Alertness Curriculum Connection – Science

Why is it that one person may notice the sound of a ticking clock and another ignore it altogether? Inside the base of the brain is the reticular formation which filters and prioritizes the signals collected by the eyes, ears, hands and other sensory organs. It identifies what deserves attention so that you are not barraged with too much sensory information. One of the ways this filter is created is based on what signals you have treated with importance in the past. The design of the human brain teaches us that alertness tomorrow will be trained by our actions today.
