Apparently the educated brain is functional even when we sleep. It enables us to keep from falling out of bed because it remembers that the edge of the bed exists and when we get too close to it we will fall. The infant rolls out of bed hence the need for a crib and side rails. The infant has an ii which is limited by limitations of matter so it cannot know the edge and the danger until it’s too late. Not rolling out of bed appears to be a learned response. June30, 2010
