At the end of the 19th century, scientists generally recognized that the number of neurons in the adult brain (roughly 100 billion ) did not increase significantly with age, giving neurobiologists good reason to believe that memories were generally not the result of new neuron production. With this realization came the need to explain how memories could form in the absence of new neurons.
