Between two adjacent myelin segments, there are approximately 1-μm-long gaps called nodes of Ranvier (Figure 1A and E). At the nodes, the axon is exposed to the extracellular space. How is the ...

The three best examples of ion channel/receptor clustering in the nervous system are found at the synapse, the node of Ranvier, and the axon initial segment (AIS). In the case of the synapse, the ...

a molecule specifically expressed in myelin. Nodes of Ranvier (arrows) are stained in green by an antibody to nodal molecule beta-IV spectrin.
