Muscarinic signaling affects attention, action selection, learning, and memory through multiple signaling cascades, which act at different timescales and which alter ion channels in cell type-specific manners. The effects of muscarinic signaling differ between cortical layers and between brain areas. Muscarinic signaling adds flexibility to the processing mode of neuronal networks, thereby supporting processing according to task demands. This review outlines possible scenarios to describe how it contributes to cellular mechanisms of attention and how it affects channeling of information in different neuronal circuits.

大脑中的毒蕈碱信号。

毒蕈碱信号通过多个信号级联影响注意力、动作选择、学习和记忆，这些级联在不同的时间尺度上起作用，并以细胞类型特异性方式改变离子通道。毒蕈碱信号的作用在皮质层和大脑区域之间是不同的。毒蕈碱信号为神经元网络的处理模式增加了灵活性，从而支持根据任务需求进行处理。这篇综述概述了可能的情景来描述它如何促进注意力的细胞机制以及它如何影响不同神经元回路中的信息通道。
