The purpose of the research was to determine the sites of the brain which upon stimulation produce purposive movement, and the necessary parameters of stimulation and programming required to elicit any form of integrated skeletal motor activity. The objectives and general approach employed were as follows 1 squirrel and rhesus monkeys were observed and photographed with motion picture film in natural behavior in cages or living compounds. This film was analyzed with a frame-by-frame projection analyzer to determine the relative sequence of various elementary limb movements in any given behavior. 2 Acute experiments were carried out on monkeys using single electrodes to extensively map the brain in order to find those loci that upon electrical stimulation produce the elementary movements observed in the compound. 3 Electrodes were chronically implanted in the sites so identified and later tested in the awake animal. 4 Attempts were made to program the elementary movements in the awake animal in such a way as to produce purposive behavior.
