The Ohio Physiological Society (OPS) became the first American Physiological Society (APS) chapter during the Spring Meeting of Council in 1995. The OPS was founded in 1986 as a professional association of Ohio physiologists. It was established with the purpose of enhancing and advancing the field of physiology as a coordinated discipline consisting of the many subdisciplines working at the molecular, cellular, and organ system levels of organization in both basic and applied areas. The current membership is from a variety of academic institutions and industries across Ohio.
