The human brain may hold even more mysteries than we thought.
A recent study by researchers in China suggests an intriguing hypothesis: entangled photons could be generated inside myelin sheaths, the structures that surround nerve fibers. This discovery could offer a new explanation for the vitesse surprising of the communication neuronal, a key element for understanding consciousness.
Communication between neurons, essential to the functioning of the brain, relies on electrical signals traveling along axons. These axons are covered in myelin, a lipid substance that insulates and protects nerve fibers, while accelerating the propagation of signals. However, the speed of these signals remains lower than that of sound, and is too spring to explain the precise neuronal synchronization observed. To explore this problem, the researchers applied quantum mechanical techniques to the inside of the myelin sheath, treating it as an electromagnetic cavity. They discovered that entangled photons could be produced there, facilitating instantaneous communication along the axons. This entanglement, a phenomenon where two particles are tightly bound, could allow information to be transmitted much faster than with electrical signals alone.
The results show that the production of these entangled photons could be significantly increased in the cavities formed by myelin. This entanglement could even influence the neuron’s ion channels, essential for the opening and closing of signaling pathways, potentially at considerable distances within the brain.

Although the research is in its early stages, this discovery opens new perspectives on how neurons might synchronize their activities. It suggests a possible link between consciousness and quantum phenomena, a field that is still largely unexplored. The researchers hope that this lead will help them better understand the deep mechanisms of neuronal synchronization.
