Introduction to Broadband Sensing
Animals have three modes of being: passive, active, and broadband. Non-selective or broadband sensing evolved for the purpose of being receptive to and aware of sudden movements and changes in the immediate environment.
Animals use this mode of sensing in combination with all their focussed activities, and while passively dozing. Broadband sensing is a vital part of the oldest, original, most natural form of staying alive.
The broadband senses are seeing, listening, and smelling.
