Scientists learn what's 'up' with a class of retinal cells in mice

... Most retinal neurons distribute their dendrites evenly around the cell body, but the upward motion-detecting cells arrange almost 90 percent of their dendrite tangle exclusively on one side of the cell body. "This lopsided arrangement literally directs the cell's function, orienting the dendrites downward...
