Reciprocal Homosexual Mounting Behavior in Paired Anosmic Male Rats
4 isolate male rats were paired after anosmia treatment with ZnSO 4 . All males engaged in repeated copulatory mounts with their partners. Reciprocal mounting continued for intervals as long as 1 hr
Exposure to Females as a Variable in Territorial Aggression of the Laboratory Rat
Four colonies of 4 male Long-Evans rats were tested for aggressive response to unfamiliar mature male isolates ( n = 16) before and after exposure to ovariectomized or intact females. The hypothesis that exposure to intact females would increase aggressive response to male intruders was rejected. Observations and physical indicators of attack and associated stress indicated minimal fighting before and after exposure to females
Intraspecific Aggression in Rats and Dimensions of Enclosure
Irritable fighting of rats exposed to noxious stimuli is negatively correlated with size of enclosure. Experimental territorial aggression, however, is independent of cage-size. Although atypically large cages have been used to investigate residents' attack upon intruders, standard pan-type plastic cages may also give comparable results. The relative influence of dimensions of enclosure emphasizes the distinction between two unique forms of consp…
Enhanced social docility in male hooded rats by dermal cautery of the vibrissal pads
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 difference…

Total Suppression of Irritable Aggression in Rats by Sensory Deprivation
Blockade of shock-elicited fighting in pairs of mature male Long Evans rats may be accomplished by combined application of lidocaine HCl to the vibrissal pads and intranasal mucosa. Nontreated males emit vigorous biting attack when paired with anosmic and facially anesthetized males; non-treated females do not engage in comparable aggressive attack upon the same target animals ( n = 4 females, 8 males)
Mouse-Killing by Devibrissaed and Facially Anesthetized Rats
18 mouse-killing Long Evans male rats were devibrissaed and facially anesthetized to determine relative importance of facial tactual sensation in detection, pursuit, and killing behavior. With vibrissae clipped plus local anesthesia of the vibrissal pads, all rats attacked and killed mice with efficiency comparable to pretest baseline measures. Results were interpreted as indicating a nonsignificant role of vibrissal sensation in maintenance of t…
Prolonged Suppression of Irritable Aggression in Rats by Facial Anesthesia
Local anesthesia of the mystacial epidermis with Lidocaine HCl reliably decreased shock-elicited fighting in 8 pairs of mature male Long-Evans rats. The decrease in aggressive responding was approximately twice as great as that reported for devibrissaed rats. Subsequent fighting, 3-hr. post-injection, did not differ from control or pre-injection baselines. Recording of intense vocalization accompanying fighting yielded objective data comparable t…
Preparation of Alcohol Solutions for Behavioral Research
Some recommendations are made on the preparation of ethanol solutions for use in behavioral research. Tap water should not be used since its nature varies from one locale to another and over time. Sterile distilled water is recommended. The concentration of the ethanol should be confirmed. A method of preparing exact volumes of ethanol—water solutions is given
