An electron micrograph of a quick-freeze deep-etch replica
of bovine cerebellum was taken with Hitachi H-7650 TEM at X 25,000, accelerating
voltage 120 kV and pseudo-colored by using Photoshop(R).
The replica of cerebellum was imaged with high-contrast and contained some spherical
structures, in which we found a small vesicle like an apple. This image reminded
us of an episode that the great physicist, Isaac Newton, discovered the Law of
Universal Gravitation when he saw apples drop from the tree. It is easily imaginable
that the flash across his mind might have electrically stimulated his central
nervous system and to develop the complicated structure with neurons, as shown
in this micrograph. The apple of neuron might be something new in the field of
TEM. Seeing is believing.
