Porter. This pulling together of researchers from different backgrounds was characteristic of Brady’s unitary vision of behavior analysis, neuroscience, and biology as aspects of the same scientific discipline that were separated only by their focus on different variables. During this time, Brady’s research group continued work on the conditioned emotional response in animal models using rats and primates, conducting studies on the effects of tetraethylammonium, amphetamine, reserpine, lysergic acid diethylamide (LSD), Nembutal, and Benzedrine. Brady’s paper on reserpine led to considerable interest from pharmaceutical companies concerned with exploring the behavioral effects of pharmacological compounds for commercial use. As a result, Brady consulted with several of these companies, who set up labs, often led by Walter Reed alums, that adopted test procedures developed at Walter Reed. Brady also conducted one of the first studies of subcortical electrical brain self-stimulation in animals and authored a paper on “Ulcers in ‘executive’ monkeys”, that provided evidence for the relationship between intermittent schedules of emotional stress and physical symptomology. This paper and its use of primate subjects caught the attention of Wernher von Braun, paving the way for Brady’s work with the space program. In addition to his research program at Walter Reed, in 1957, Brady joined the faculty of the Psychology Department at the University of Maryland, College Park and became the director of the Psychopharmocology Laboratory, established with the help of a grant from the National Institute of Mental Health, the first they awarded in behavioral pharmacology. Early additions to the lab at College Park were Charles R. Schuster and Travis Thompson, who would go on to co-write the first textbook in behavioral pharmacology. As detailed in a 1961 "Science" paper, Schuster, Thompson, and Brady developed a procedure with rhesus monkeys that allowed the monkeys to intravenously self-administer a saline solution through lever pressing behavior. Later they would extend the self-administration procedure to the testing of drug abuse liability which would become a major focus of Brady’s laboratory at Johns Hopkins University. Due to Brady’s experience working with primates, Wernher von Braun of the U.S. Army Ballistics Agency solicited the help of Brady in training primates to provide data for the first live organism sub-orbital spaceflights initiated by the U.S. Brady and his collaborators, mainly Murray Sidman, who developed the avoidance procedure which would eventually take his name, trained rhesus monkeys to press a lever at specific time intervals to avoid an electric shock.
