Liljencrantz et al. report the failure of observing contagious itch behavior using mice injected with histamine as the demonstrators. Analysis of their results shows that the histamine model is limited by inadequate frequency and duration of scratching bouts required for contagious itch test. To streamline the contagious itch test, the screen paradigm is highly recommended.

回应评论“小鼠传染性瘙痒行为的分子和神经基础”

Liljencrantz 等。报告使用注射组胺的小鼠作为演示者观察传染性瘙痒行为的失败。对他们的结果的分析表明，组胺模型受到传染性瘙痒测试所需的抓挠发作频率和持续时间不足的限制。为了简化传染性瘙痒测试，强烈建议使用屏幕范例。
