First Day City: First Day of Issue Ceremony was held in Cleveland, Ohio, at The Great American Stamp Show.
About the Life Magnified Set: These 20 stamps were issued to showcase life undetectable by the human eye alone. All 20 stamps picture photographs taken using special techniques and the aid of a microscope. The set celebrates the beauty and complexity of microscopic organisms and parts of organisms, the study of which have had various impacts on humans.
History the stamp represents: Did you know the brain of a mouse is 90% identical to the brain of a human? Perhaps the biggest difference is that a mouse has approximately 8-14 million neurons in its cerebral cortex (the outer layer of the brain), while a human has over 10-15 billion. This has allowed scientists to study certain diseases and disorders in mice and develop solutions to the same problems in humans.
Neurons (nerve cells) are responsible for sending electrical signals to all other cells in the body. There are three different categories in most living things. Sensory neurons respond to touch, sound, or light that affects cells in the sensory organs. They also send signals to the spinal cord and brain. Motor neurons get signals from the brain and spinal cord to control muscle movement and related processes. Interneurons connect neurons within the brain and spinal cord.
When looked at under a microscope, neurons almost resemble a paint splatter. They have a thicker center (soma) plus axons and dendrites (arms extending from the soma). Dendrites branch out a few hundred micrometers while axons reach as far as a meter in humans (though most are closer to a millimeter). They are amazingly complex for such tiny structures. It is this complexity that allows them to perform one of the most important functions in the body.
