Light micrograph of the human cerebellum, the hindbrain, showing (at bottom) a row of large, flask-like Purkinje cells, which are among the largest nerve cells in the body. The long dendrites from the Purkinje cells extend into all three layers of the cerebellar cortex. The cerebellum receives input from areas of the brain responsible for initiating movement, & from the body's sense receptors. The mechanisms by which its cells integrate motor & sensory information to coordinate fine movement are obscure. Magnification: x500 at 35mm size.
