Scientists have taken another step toward understanding what makes the human brain unique.

An international team has identified a kind of brain cell that exists in people but not mice, the team reported Monday in the journal Nature Neuroscience.

“This particular type of cell had properties that had never actually been described in another species,” says Ed Lein, one of the study’s authors and an investigator at the Allen Institute for Brain Science in Seattle.
