The fast rhythm linking the left and right halves of the brain has a new name: “splines,” so-called because they visually resemble mechanical splines, the interlocking teeth on mechanical gears.

Omar Ahmed, assistant professor of psychology and lead author of a new study appearing in Cell Reports, says that splines represent a pattern of rhythmic communication across the left and right brain that is different from other known brain rhythms.
