I am mindful of the demonstration carried out by the late R. C. Gary for his medical students at the University of Glasgow. He asked that every student in his class think up a different sensory input for a cat - any kind of odor, region of touch or pull, local temperature change, stretch or flexion, movement, sound, and the rest. Having amassed a long list, he produced a decerebrate cat with a needle electrode implanted in its anal sphincter, and started to work through the list. Every stimulus produced a burst of spikes!
