The Very First Synapse

This is the very first synapse in your visual system.  This is cone photoreceptor terminal showing ribbon synapses (the dark lines), making synapses onto bipolar cell and horizontal cell dendrites.  These synapses are just a few of the literally trillions of synapses in your body and have to be imaged using 80,000 electron volts passed through a section of tissue that is 70nm thick, thinner than the wavelength of light.  This is of course one of the major reasons why The Singularity proposed by Kurzweil will never happen.  The energy required just to capture the identity, position and parterships of all the synapses in your body would be astronomically big, even if you could map all their identities and locations.
