I'm having difficulty recalling the word for the unique sensory space of an organism. Or it might be the word for the impression derived from those unique senses, I'm not totally sure. It would be used as follows:
The human ______ is comprised of sight, smell, taste, touch and sound, and differs from the ______ of a bat.
I believe I encountered it in Valentino Braitenberg's "Vehicles: Experiments in Synthetic Psychology."
