though, Macleod pointed out some flaws in their experimental design and gave them advice about directions in which to work. Banting's original method of isolating insulin required performing surgery on living dogs, which was too labor-intensive to produce insulin on a large scale. Best then set about finding a biochemical extraction method, while James Bertram Collip, a chemistry professor on sabbatical from the University of Alberta, joined Macleod's team and worked in parallel with Best. The two of them succeeded within days of each other. When Banting agreed to receive the prize, he decided to give half of his prize money to Best. Macleod, in turn, split his half of the prize money with Collip. 1906 Camillo Golgi and Santiago Ramón y Cajal were jointly awarded "in recognition of their work on the structure of the nervous system". However, their interpretation of discoveries were directly in opposition. Much as Golgi made significant contributions to the techniques in the study of nervous system in terms of actual structure, he made a completely erroneous conclusion that nervous system is nothing but a single continuous network, the notion called reticular theory. On the other hand, Ramón y Cajal described nervous system as composed of interlinking nerve cells or neurons as suggested by a theory called the neuron doctrine. Golgi strongly advocated the reticular theory such that even his Nobel lecture was a direct attack on Cajal's work and the neuron doctrine, and even depicted a diagram of continuous network which he claimed was "an exact reproduction after life". Therefore, recognising a work on wrong conclusion is inappropriate. The controversy and rivalry between the two scientists lasted even after the award of the Nobel Prize. The award is even dubbed as creating the "storm centre of histological controversy". Cajal even commented that: "What a cruel irony of fate of pair, like Siamese twins united by the shoulders, scientific adversaries of such contrasting character!" The neuron doctrine turned out to be a more correct description, and Golgi was proved wrong with the development of electron microscopy in the 1950s by which it was clearly demonstrated that neurons are individual cells in the nervous system, and that they are interconnected through gaps called synapses. Recent studies suggest that there are notable exceptions. Electrical synapses are more common in the central nervous system than previously thought. Thus, rather than functioning as individual units, in some parts of
