Myelinating Schwann Cell Polarity and Mechanically-Driven Myelin Sheath Elongation [PDF]
Frontiers in Cellular Neuroscience, 2018 Myelin sheath geometry, encompassing myelin sheath thickness relative to internodal length, is critical to optimize nerve conduction velocity and these parameters are carefully adjusted by the myelinating cells in mammals.

Treadmilling Model for Plasticity of the Myelin Sheath. [PDF]
Trends Neurosci, 2019 We propose a mechanism for myelin plasticity that would complement synaptic plasticity by adjusting conduction velocity for optimal spike-time arrival. In the proposed treadmilling model, myelin sheath thickness is a dynamic balance between the rates of new myelin deposited adjacent to the axon and removal of the outermost layer.

Shielding effects of myelin sheath on axolemma depolarization under transverse electric field stimulation [PDF]
PeerJ, 2018 Axonal stimulation with electric currents is an effective method for controlling neural activity. An electric field parallel to the axon is widely accepted as the predominant component in the activation of an axon.

Role of Connexin-Based Gap Junction Channels in Communication of Myelin Sheath in Schwann Cells [PDF]
Frontiers in Cellular Neuroscience, 2019 Peripheral nerves have the capacity to conduct action potentials along great distances and quickly recover following damage which is mainly due to Schwann cells (SCs), the most abundant glial cells of the peripheral nervous system (PNS).
