What is the word for the combined senses of an organism?

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."

If you're looking for a single noun: sensorium.

sen·so·ri·um
1. a part of the brain or the brain itself regarded as the seat of sensation.
2. the sensory apparatus of the body.
