Behavioral lateralization has been documented in many vertebrates,but little has been defined for the neuronal basis of it. Here, we studied scale-eatingbehavior in cichlids in a tank through high-speed video monitoring and quantitative assessmentof behavioral laterality and kinematics. The maximum angular velocity and amplitude of bodyflexion were significantly larger during attacks on the preferred side compared to those onthe nonpreferred side. No such lateralized movement was found in acoustically evoked flexionduring the escape response, which is similar to flexion during scale eating, suggesting thatthe neuronal circuits controlling body flexion during scale eating may be functionallylateralized upstream of the common motor pathway.

许多脊椎动物都有行为偏侧化的记录，但对其神经元基础的定义却很少。在这里，我们通过高速视频监控和行为侧向性和运动学的定量评估，研究了水族箱中慈鲷的食鳞行为。与非首选侧相比，首选侧攻击期间身体弯曲的最大角速度和幅度明显更大。在逃避反应期间的声诱发屈曲中没有发现这种侧化运动，这与鳞片进食期间的屈曲相似，这表明在鳞片进食期间控制身体屈曲的神经元回路可能在共同运动通路的上游功能侧化。
