Meta-control in pigeons individual data

In situations where the two sides of the brain process contradicting information that leads to incompatible response options, the brain requires efficient conflict-solving mechanisms. Such conflicts can arise particularly in lateralized brains, in which the hemispheres differ in coding strategies or in focus of attention and hence, consider different information for decision-making. Meta-control, in which one hemisphere constantly dominates response selection independent from its processing competence, can be a mechanism, which minimizes interhemispheric interferences and ensures fast behavioral reactions. We therefore confronted pigeons with a task in which two stimulus classes were brought into conflict. In this situation, pigeons display individual meta-control despite equal categorization performances of both brain hemispheres. Thus, hemispheric dominance arises specifically in interhemispheric conflict situations. As a signature of the underlying neuronal mechanisms, analysis of re...当大脑两侧处理相互矛盾的信息并由此产生互斥的反应选项时，大脑需要高效的冲突解决机制。此类冲突尤其容易出现在偏侧化大脑（lateralized brain）中：这类大脑的两个半球在编码策略或注意力焦点上存在差异，因此在决策时会考量不同的信息。元控制（Meta-control）指单个半球不受自身加工能力限制，持续主导反应选择的机制，该机制可最大限度减少半球间干扰并保障快速的行为反应。为此，我们让家鸽完成一项可引发两类刺激类别产生冲突的任务。在此情境下，尽管家鸽两侧大脑半球的分类表现相当，但它们仍展现出个体层面的元控制行为。由此可见，半球优势仅在半球间冲突情境中才会显现。作为潜在神经元机制的标志性特征，对……的分析
