When a electron moves from one neuron to another. If an electron moves at all it creates a wave like wake in the electromagnetic field. Electron, Neutron, abd Protons all create wave like wakes in the field they are releated to.

These fields associated with the particles are believed to cover all spacetime because if you entangled certain particles especially the electron the entangled counter part will always mirror its parent regardless of distance or even time so we are said to be connected to everything even frame of reference at any moment in the timeline.
