This article focuses on the researchers John Russel Reynolds and Hughlings Jackson with their work-related to positive and negative cerebral symptoms. Reynolds is often remembered for his description of eclamptic convulsions in children, which at that time referred to various fits including febrile convulsions. Perhaps of greater import his 1861 paper espoused the concept of positive and negative neurological symptoms as being the excess or negation of vital properties. Generally regarded as a worthy, caring physician he was a popular and fluent lecturer, although shy and serious in manner. The origins of positive and negative symptoms are inextricably intertwined with the researcher Herbert Spencer's dissolution and evolution of the nervous system. Jackson extended Spencer's idea to positive and negative symptomatology.
