Location, location -- Cell sizes, lives influenced by host size

ns have more complex neurons than small ones. Instead of saying neurons are larger because of demands for information processing, it suggests information processing might be constrained by the fact that neurons are larger. But it doesn't answer why different neurons get bigger to different extents, so there is still a lot of room to develop answers about why neurons scale up the way they do."

More study is needed to understand the interplay between an organism and its cells, scientists say.

"Despite the progress that has been made in cell biology, we still have a relatively poor understanding about general characteristics of cells across species," Savage said. "The focus has been on how cells affect the whole organism, not on how the size of the organism and its energy requirements affect the cells."
