Signal In, Signal Out

The dorsal root ganglion is a little clump of neurons near your spinal cord. These little globs transmit messages about temperature, pain, chemicals, and spatial orientation to the central nervous system. If you’re familiar with the knee reflex (when someone whacks your knee and you involuntarily kick them), then you’ll be pleased to know that the dorsal root ganglion is part of the reflex arc. Purchase this gold-plated DRG neuron necklace for yourself or for a friend. It’s also perfect for soccer players, physicians, nurses, and starry-eyed pre-med students.
