title: Differentiation of activity of three mouse strains with magnetic pickup apparatus.
abstract: An activity pickup, when used with a high-gain amplifier, permits records to be made of essentially all the activity of a mouse. The sensitivity is such that the differences in the activity patterns of strains of mice can be determined.
