In a study published in the Cell Press journal Neuron, Jianguo Gu ... TRAAK act as the principal potassium channels in the Nodes of Ranvier of a rat myelinated nerve. More importantly, they ...

Recent work from several laboratories, including my own, have now shown that the AIS is intrinsically specified by the neuron, but node of Ranvier formation and placement is dictated by extrinsic, ...

Each neuron is connected to another 1,000 neurons ... There are small gaps in the myelin coating, called nodes of Ranvier. The action potential jumps from gap to gap, allowing the signal to ...

The myelin sheath is a protective covering that surrounds fibers called axons, which are the long thin projections that extend from the main body of a nerve cell or neuron. This sheath is composed ...

Along the axons, the myelin sheath is regularly interrupted by structures referred to as the nodes of Ranvier, and its insulating effect ensures that action potentials can be built up (i.e. signal ...
