[Neurocellular index].
If in an experimental or a clinico-morphological investigation a possible destruction of neural cells is suggested, it is recommended to apply the neurocellular index which is calculated as an average ratio of neural cells with a visible nucleus and nucleolus to neural cells with an indistinguishable nucleus or nucleolus or both in the same histological section. The index can serve as an objective proof on the process of cellular destruction and given an idea of its degree, expressed in numbers, suitable for comparative statistical-probable estimation. Applying this method, it is possible to objectively prove the fact of a gradual diffuse destruction of a certain amount of neural cells in the brain of old persons.
