Myelin sheaths are sleeves of fatty tissue that protect your nerve cells. These cells are part of your central nervous system, which carries messages back and forth between your brain and the rest of your body.
A demyelination can result in damage to the protective covering (myelin sheath) that surrounds nerve fibers in your brain, optic nerves and spinal cord. When the myelin sheath is damaged, nerve impulses slow or even stop, causing neurological problems.
Terahertz exposure enhances neuronal synaptic transmission and oligodendrocyte differentiation
Oligodendrocytes produce the myelin sheath insulating neuronal axons (analogous to Schwann cells in the peripheral nervous system).
The myelination process is enhanced after THz exposure.
THz exposure promotes neurite outgrowth and increases the expression of synaptic-associated proteins.
Neurons rely on the action potential (AP) to deliver information from integrating the synapses and cell body, and the neurite outgrowth also needs the action potential to send growth information.
These results suggest that THz irradiation enhances neuronal activities.
THz irradiation significantly promoted myelination and long myelins were prominent in the co-cultures. These observations suggest that THz irradiation enhances the cross talk between neurons and oligodendrocytes, then accelerates the process of myelination.
