in Seewiesen, successfully conducting a quantitative demonstration of the "law of heterogeneous summation," whose model predicted that "different features of a stimulation in a [led] to an independent behavioral stimulation in the receiver". Much of his work eventually led to the testing and production of evidence contrary to Lorenz's theory of the psychohydraulic model of motivation (specifically aggression) using male Chiclidae. Such was his willingness to venture into new neuroethological territories despite the established research at the time. His status as neuroethologist was further established when he moved to the Scripps Institution of Oceanography at the University of California, San Diego, in 1972 as a post-doctoral investigator in Theodore Holmes Bullock's laboratory. His appointment to faculty in 1973, then to the position of full professor of behavioral physiology in 1977 followed his decision to decline the position of Director at the Max Planck Institute for Behavioral Physiology in Seewiesen. His work at UCSD led him to publish widely about the neural bases of the jamming avoidance response, the first vertebrate example of an entire behavioral pattern that could be explained from sensory input to motor output. The built-in electric organ of Eigennmania that gave millivolt discharges was found to be adaptive for location of external objects and for communication (electrolocation and electrocommunication, respectively). Heiligenberg continued to study potentially more complex social behaviors, including courtship and aggressive encounters. The decades' worth of work was expressed through the book, Neural Nets in Electric Fish, in which he explains observed phenomena of the jamming avoidance response, the nature of the electrical stimulus, the neural networks triggering them, and even explains it with respect to systems for other senses and in other species. His inclination to successfully use computational methods and modeling made him a pioneer in the neuroethology community. Heiligenberg lab During Heiligenberg's time at Scripps, he directed his fellow researchers and graduate students toward exploring behavioral phenomena through neuroethological methods and interests. His openness with his graduate students was notable, as he encouraged them not only to use and learn new techniques and other interests in different fields, but was also willing to allow them independently started projects and papers published without being named as a co-author. More importantly, his personal work employed the useful aspects of both neurophysiology and ethology, whose approaches addressed the single-unit interactions and more complicated patterned processes, respectively. In his own words, his methodology was based on
