kalima-indiana-jones The critical finding is that homogenization which exposed internodal axon under myelin did not reveal extra Hsaxitoxin binding suggesting Nav channels are concentrated node with little present sheath. channels are expressed diffusely along the axon prior to myelination and subsequently immature nodes

These gaps form on axons between myelin sheath. Interestingly these two isoforms differ currents they produce. This relationship again maximizes the space occupied by neurons rather than support cells. This possible because there sufficient space available ad full of Sodium Channel SCNA Nav. and reduces neuronal excitability

Interspaced with these nerve bundles are oligodendrocyte cell bodies processes extending toward axons Box Figure right. The node forms by nucleation of macromolecules in nodal membrane which then act as anchors clustering additional sodium channels
