Neuroscience in Latin America Five Decades of Flourishing Neurochemistry in the Region

We describe the development of neurochemistry in Brazil, Argentina, Uruguay, and Chile in the XX century through Latin American scientists who pioneered the discipline in their countries. In addition, we analyze the research groups that succeeded the pioneers and the fields explored in greater depth in different countries. We examine the history of glial cell research and the efforts made despite financial constraints. We also highlight the role of the International Society of Neurochemistry (ISN) in the history of neurochemistry in Latin America. A special section is dedicated to neurochemistry in Venezuela, given its significant role in the past.
