Acid-sensing ion channel 1a (ASIC1a) acts as the main proton sensor, is a novel synaptic receptor, and plays critical roles in learning and memory. In this issue, Song et al. demonstrate the post-synaptic targeting and strong spatiotemporal dynamics of ASIC1a in dendrites and spines using self-designed tools. The cover image is derived from the well-known Chinese fairytale called “Monkey King Thrice Defeats the White-bone Demon (孙悟空三打白骨精)”. With his piercing eyes, Monkey King was able to distinguish monsters from ordinary human beings at the first glance. The piercing eyes represent the newly-developed tools to visualize the ASIC1a channel, and the elbow joint of the white-bone demon seen by Monkey King depicts synaptic connection, which is highlighted in the circle and illustrates the location and mobility of ASIC1a channels in excitatory synapses.
