Aggressive behavior inhibition by serotonin and quipazine injected into the amygdala in the rat 总被引:1,自引:0,他引:1
The effects on aggressive behavior, open-field activity, and pain threshold of bilateral microinjections of serotonin (20 micrograms) and quipazine (20 micrograms), the direct serotonergic receptor agonist, into the cortico-medial amygdala were investigated in Wistar rats. Both drugs significantly prolonged the attack latency in isolated killer rats (predatory aggression model), and suppressed the incidence of aggressive postures/attacks in shock-induced fighting test (affective aggression). The only difference in the open-field behavior was the lower number of central square entries in drug-treated compared to saline-injected rats. None of the substances produced any significant change in jump threshold. It is concluded that stimulation of serotonin receptors within the amygdala produces inhibition of affective and muricidal behavior in isolated rats. The effect does not seem to be dependent on changes in general activity and pain sensitivity. 相似文献

The authors present a short review of the pertinent literature and report on their own neuropsychiatric findings following internal craniocerebral injuries, at the same time drawing attention to the necessity of psychological examination. Statistical comparisons with the international literature are complicated owing to the different classifications used for craniocerebral injuries. 相似文献

The total number of different responses, given by a group of subjects to a stimulus word in a single-word, free-association situation ( D ), is a primary determinant of associative response latency (Tecce & Glassco, 1965; Flekkøy, 1981). D has traditionally been assumed to reflect a word's associative potential, and the increased latency to high D words has been explained by response competition. The results of the present experiments indicate, however, that D reflects in an inverse manner semantic autonomy , high D words requiring more contextual information for their semantic specification than low D words. The process of semantic specification requires time, creating the positive D -response latency relationship. Based on a semantic interpretation of D , associative response heterogeneity may be used as an index of a word's semantic autonomy. 相似文献

This is the second of two papers dealing with symbolic-experiential treatment of marital issues. The first—Early Stages in Experiential Marital Therapy — discussed three early stages. This paper discusses regressive work with couples, including engagement with the family of origin. 相似文献
