Detailed explanation-1: -Golgi staining was used by Spanish neuroanatomist Santiago Ramón y Cajal (1852–1934) to discover a number of novel facts about the organization of the nervous system, inspiring the birth of the neuron doctrine. Ultimately, Ramón y Cajal improved the technique by using a method he termed “double impregnation".
Detailed explanation-2: -Golgi-Cox staining is a useful method for visualizing the dendritic branching pattern and dendritic spines, which allows us to study the relationship between behavioral phenotype and morphological changes of neurons.
Detailed explanation-3: -Scientists confirmed the theory by using the Golgi staining technique to show the gaps, or synapses, between neurons. Golgi and Ramón y Cajal shared the Nobel Prize in Physiology or Medicine to in 1906.
Detailed explanation-4: -Golgi believed in a reticular view of the structure of the nervous system, whereas Cajal supported the neuron doctrine. According to the reticular theory, there is fusion among neural elements; axons cross and re-cross one another fusing and forming a large neural network.
Detailed explanation-5: -Discovery. Dendritic spines were first seen by microscopists of the late nineteenth century in brain sections stained using the Golgi method (Figure 1), named after the Italian neuroanatomist Camillo Golgi who introduced it in 1873.
