| 内容記述 | In order to classify emotional states of animals, common marmosets may be useful subjects. It is well known that there is strong correlation between the patterns of vocalization and the specific behavior in the common marmosets (e.g., 'chatter' call corresponds aggressive behavior). This suggests that the vocalization patterns of marmosets may be useful to classify emotional states of the animals. Here, we collected vocalization patterns of the marmoset in the isolated environment and tried to map their corresponding emotional states. Two adult common marmosets were used in this study. Each animal was isolated in the novel cage, and habituated for 5 sessions of 60 min long. The vocalization patterns in the first 30 min in each session were analyzed based on producing sonogram. The number of patterns of vocalization decreased as the session progressed, so that they vocalized mainly 'phee' call, which corresponds 'calling partners', after habituation. They often vocalized with specific pattern, 'tsikegg' call (one'tsik'call followed by a few'egg'calls) at the first habituation trial. As the sessions of habituation progressed, the number of 'tsikegg' call declined significantly. This suggests that 'tsikegg' call reflects anxiety evoked by the novel environment. We applied this vocalization pattern analysis to a methamphetamine (METH) test in the same environment. The number of 'tsikegg' calls in 30 min significantly increased with METH (2mg/kg) treatment in comparison with the saline treatment, suggesting that METH makes marmoset anxiety. Taken together, vocalization patterns of marmosets may allow us to identify their emotional states with higher validity. | |||||
