“…The absence of any sustained fighting in cauterized pairs of animals suggests that cautery is comparable to vibrissal anesthesia in experimentally naive animals (Thor et al, 1974). Although n o controls for stress of cautery itself were included (that is, controls cauterized in areas other than the vibrissal pads), it would seem quite remote that generalized stress of cautery would almost totally inhibit aggressive response t o footshock.…”

“…Since both shock-elicited fighting and colony intrusion fighting appear to be strongly influenced by the cautery technique, other forms of social aggression, for example, competitive fighting or schedule-elicited fighting, may also be affected. Prior investigations with perioral anesthesia (Thor et al, 1974;Thor and Ghiselli, 1975b) have demonstrated that former experience may influence subsequent aggressive responding even though vibrissal organs are anesthetized. The permanency of vibrissal cautery is still an open question and one that may have varying answers depending upon the experimental model.…”

“…Lucian0 (1 974b) has reported that anosmic intruders fail to display defensive behavior and are attacked less than blind or normal intruders. In the shockelicited fighting paradigm, local anesthesia of the vibrissal pads negates fighting in experimentally naive pairs of rats (Thor et al, 1974) but has only a temporary depressant effect upon mouse killing (Thor and Ghiselli,1 9 7 5~) .…”

Ablation of the vibrissal pads in rats causes subsequent deposition of scar tissue with little or no regrowth of the vibrissae. Cauterized and intact mature male Long Evans rats were tested for shockelicited fighting, mouse killing, and colony intrusion forms of laboratory‐induced aggression. The results revealed that only conspecific social fighting is blocked by ablation of the major vibrissal follicles. Although no significant group differences were noted in tests for mouse killing, shock‐elicited paired fighting and territorial defense against a strange intruder were minimal in cauterized groups. The results emphasize the importance of specific sensory experience in reference to distinct forms of aggressive responding and support a new experimental technique for further investigation of sensory interactions with sources of aggressive behavior.

“…In untrained rats, tactual sensory information from the snout is critical for the occurrence of shock-elicited aggression; without such information, no aggression occurs (Thor, Ghiselli, & Lambelet, 1974). Olfaction plays a lesser eliciting role than tactual information, while visual cues appear irrelevant (Ghiselli & Thor, 1975).…”

Albino rats tested for shock-elicited aggression on occasion emitted periodie ultrasonie calls. The fundamental frequency of these calls was about 24 kHz, with harmonics appearing at 72 and 120 kHz, and the calls lasted as long as 3·4 sec. These calls were emitted by rats which had adopted an upright submissive posture following attack(s). These long 22·26-kHz calls may serve to inhibit or prevent unlearned behaviors in rats.

“…Several different subhuman models of aggression have been used to investigate aggressive behavior. The shock-aggression model as originally studied by O' Kelly and Steckle (1939) and, more recently by a variety of investigators (e.g., Thor, Ghiselli, & Lambelet, 1974;Ulrich & Azrin, 1962), provides a particularly good model of defensive fighting since the eliciting stimulus can be precisely controlled. However, the latter advantage is sometimes illusory, especially where the behavior is elicited by grid shock.…”
