title: Circular countercurrent-distribution behavioral genetic maze.
abstract: An inexpensive, easily constructed apparatus for mass screening of taxes of small animals with a rapid and accurate assignment of individual behavior scores has been described that should be of utility in hastening a behavioral geneticist's chores and allow him to handle more populations with fewer mazes. Also, the apparatus is well suited for use within the constraints of the undergraduate laboratory.
