The Amazing Brain: Turning Conventional Wisdom on Brain Anatomy on its Head

Silas Busch at the University of Chicago captured this slightly eerie scene, noting it reminded him of people shuffling through the dark of night. What you’re really seeing are some of the largest neurons in the mammalian brain, known as Purkinje cells. The photo won first place this year in the Brain Research through Advancing Innovative Neurotechnologies® (BRAIN) Initiative’s annual Show Us Your BRAINs! Photo and Video Contest. While humans have them, too, the Purkinje cells pictured here are in the brain of a mouse. The head-like shapes you see in the image are the so-called soma, or the neurons’ cell bodies. Extending downwards are the heavily branched dendrites, which act like large antennae, receiving thousands of inputs from the rest of the body.
