Role of the mystacial vibrissae in the control of isolation induced aggresion in the mouse

摘要: Adult male Swiss Albino mice were isolated from conspecific contact for 10 days. Removal of the mystacial vibrissae and subsequent anesthesia vibrissal pad reduced number aggressive social encounters that normally ensue upon reintroduction a conspecific. This reduction occurred under conditions in which latencies initial essentially unchanged. These results are consistent with previous reports importance integrity control attack behaviors variety other paradigms, extend observations to novel species paradigm. Recent developments study agonistic behavior have pointed highly specific sensory input elaboration responses. In particular, trigeminal mechanisms including organs located at facial lipline been shown influence occurrence terminal components such as orientation biting many models aggression. For example, Flynn his colleagues (Flynn, 1967, 1972; et al. 1971; MacDonnell Flynn, 1966a, b) factors centrally elicited cat, both through direct alteration fields central stimulation aggression producing sites, additionally disruption patterns interruption '~f afferent input. addition, implicated shock elicited, biochemicaUy induced, predatory rat via peripheral manipulations removal (Thor Ghiselli, 1973, 1974a, b, 1975).
