It takes around eight minutes and twenty seconds for light from the sun to reach the earth. It then takes another half a second for that light to be reflected off an object, detected by the retina, trigger signals that travel along the optic nerve, pass the optic chiasm, continue down the optic tract, go through the Lateral Geniculate Nucleus, arrive at the primary visual cortex and spread to wider areas of the cortex and to finally then somehow become part of consciousness. If we decide to move in response to that light, there is a similar time lapse. Specific neurons in the brain must activate continuously for at least half a second before we make the decision to move. To some, consciousness is divine; to others consciousness is the result of the contemporaneous firing of distributed populations of neurons feeding through a dynamical core of deep brain activity.
