1 Letters refer to following manipulations. A: affective defense; B: banging noise ; C: clicks; D: dropping cat; E: eating horsemeat; F: flashes; G: grasping paw; H: passive head movement; L: lifting cat; N: scraping noise; O: opening cage; P: pinching tail; R: leg retraction; S: stroking cat; T: tapping partition separating cats; U: standing up; b: baseline, spontaneous activity.

2 Mean firing rate per second of baseline data. Distribution is Poisson unless indicated as normal by letter "n".

3 Mean firing rate per second based on one-second measures only.

4 Highest firing rate during any one second of any manipulation other than affective defense. Letter symbols as above.

5 Although cell fired one spike when cat was dropped, it was included in this category because its response characteristics resembled those of other "if and only if" cells more closely than any other type.

6 Inconsistent response, present in only 4 of 11 trials. Inconsistent responses are not reported in these tables for other cells.
