Peter John Snow (born 25 February 1948) is an Australian neuroscientist and author.
Shortly after his birth in Jubbulpore, India, his father retired from the British Army and moved to Australia. In 1970 Snow graduated with First Class Honors in Zoology. He then enrolled in a PhD program at the University of Alberta, completing his dissertation in invertebrate neurobiology in 1974 before moving to the University Edinburgh, as a Canadian Medical Research Fellow. During this period he pioneered techniques for injecting single mammalian nerve cells with tracers and used these to extensively study the neuronal microcircuitry of the sensory systems within the spinal cord.
In 1976, Snow was awarded a Queen's Fellowship in Marine Science to study the nervous system of crustaceans at the Australian National University. In 1978, he was appointed to the faculty of the Anatomy Department, University of Queensland where, until his retirement in 1998, he supervised several large medical research programs on the plasticity of the central nervous system and the representation and control of pain. Over this period Snow also conducted extensive studies on the neurobiology of sharks and stingrays which included research on their somatosensory systems, centers of aggression and ability to withstand extreme hypoxia.
Since retiring from university Snow has devoted himself to writing 'The Human Psyche' and to delivering a number of lectures on the human psyche, including the Alberta Heritage Foundation of Medical Research Lecture.
Snow is a member of the International Brain Research Organization (IBRO) and an emeritus member of the Society for Neuroscience (USA). He was also a founding member of the Australian Neuroscience Society (retired), the Australian Physiological & Pharmacological Society (retired) and the Primate Society of America (retired)
Snow is author of numerous scientific papers, reviews and book chapters and is coauthor, with Dr. P. Wilson, of an extensive monograph on plasticity and development in the somatosensory system. In late 2009, he published the first comprehensive, neuroscientifically-based book on the human psyche.
