Every day I search brains at high magnification at work, and once in a great while I find a neuron shaped like a letter or face. You can have a name of your choosing written in myelin in the thalamus of a brain (newer letters come from the entorhinal cortex). The dark black forming the letters is the myelin sheath surrounding an axon, elsewhere, mitochondria and synaptic vesicles can be seen.

I also frequently find faces, follow instagram.com/neuropareidolia. Below is a face formed out of mitochondria in a dendrite.
